5 Days in Koh Samui

A big island with busy beaches, quiet temples and a Gulf rainy season that ends just before January.

5 days, 26 stops

Koh Samui is Thailand's second-largest island after Phuket, about 25 km long and 21 km wide, and for most of its history nobody visited it on purpose. Fishermen from the Malay Peninsula settled here centuries ago, coconuts paid the bills, and the island had no roads until the early 1970s, when a trip across it was a day's walk through the jungle. The first backpackers arrived on coconut boats, the airport opened in 1989, and by the 1990s the boats were full. That short history explains the place: a coconut island that turned into a resort in one generation.

So be clear about what you're getting. Samui is not Thailand's most beautiful island, and the two big beaches, Chaweng and Lamai, are busy and built up. What it does well is range. Within an hour's drive you have a 12-meter golden Buddha, a temple with an eighteen-armed goddess standing in a lake, a mummified monk in a glass case, waterfalls, a Friday night market in an old fishing village, and a boat to a national park of 42 limestone islands. Five days is the right length: enough for the island, one day on the water, and a rest day, without turning the trip into a checklist.

The plan is organized by coast. Day one is the north (the Big Buddha, Wat Plai Laem, Choeng Mon and Fisherman's Village), day two the east-coast beaches from Chaweng to Lamai, day three the south and the hills (the mummy, the waterfalls, the Secret Buddha Garden), day four the boat to Ang Thong Marine Park, and day five the north-west and the old port of Nathon. Start on a Friday if you can: the big night at Fisherman's Village is Friday, and day one ends there. Koh Tao, Koh Phangan, the Full Moon Party and Khao Sok are in the "more time" section. For the country in general, see Thailand.

Day 1Bang Rak, Bophut, Choeng Mon

Day 1: Big Buddha, Plai Laem and Fisherman's Village

The north-east corner of the island is compact: everything today is within 15 minutes of everything else, near the airport. Start on a Friday, because the market at Fisherman's Village is at its biggest that evening (other nights are quieter, if they run at all). Temples are the one thing here with a dress code, so wear something that covers shoulders and knees, or carry a light shirt and a sarong.

    Big Buddha (Wat Phra Yai)

    The Big Buddha sits on a small island, Ko Fan, joined to Samui by a short causeway just north of the airport. The gold-painted figure is 12 meters high and was built in 1972, which makes it younger than the first road around the island. It shows the Buddha in the Mara posture, calm after resisting the temptations of Mara, the lord of illusion. Wat Phra Yai is the official name, but nobody uses it.

    Climb the stairway lined with naga serpents, walk around the base where the bells hang, and look back over Bang Rak and the airport. It doesn't take long, and the bazaar at the bottom sells tourist items and amulets. Go early, before the heat and the tour buses.

    Wat Plai Laem

    Less than a kilometer away is the better temple. Wat Plai Laem is a modern complex built around a lake, with Chinese and Thai elements, partly designed by the Thai artist Jarit Phumdonming. The main statue isn't the Buddha. It's the eighteen-armed Guanyin (Cundi), the bodhisattva of compassion, standing white and gold in an open pavilion on the water, with a laughing white Budai nearby and small shrines to Ganesha, Vishnu and Shiva.

    This is an active temple, so keep your voice down, don't point your feet at statues and don't climb on anything. A morning visit also gives you softer light on the water. Sources disagree on hours (opening between 06:00 and 08:00, closing between 17:00 and 18:00), so don't plan around the last half hour.

Afternoon
  1. Experience2-3 hoursFree; a beachside massage is about 300 THB an hour (9 USD)

    Choeng Mon Beach

    Choeng Mon is the quiet bay on the north-east tip, a crescent of wide white sand about 500 meters long, with a rocky end on one side and a small island at the other. It's calm and clean, and a handful of upscale resorts dominate it, so there's not much to do beyond swimming, lying down and eating. That's the point.

    Kayak out to the islets of Ko Fan Noi and Ko Fan Yai at the eastern end. At low tide you can wade across to Ko Fan Yai, but stay below the high-tide line, because most of the island belongs to a private resort. There is some coral at the west end and around the islets, but with an east wind the water gets choppy and visibility drops close to zero.

    Fisherman's Village, Bophut

    Bophut's Fisherman's Village is one of the few places on Samui that keeps some of the island's original Thai-Chinese atmosphere. A narrow lane of old Chinese shophouses runs along the beach, now converted into restaurants, spas, boutiques and small hotels. There has been a conscious effort to keep the commercial side of Thai nightlife out, so there are no go-go bars. Roughly 30 bars and restaurants line about 700 meters of street.

    Come around 17:00, before the market fills the lane, and walk down to the beach for the sunset. Bophut is known for its sunsets and for variety on the plate: French, Italian, seafood and good Thai. The water is calm but often murky, especially around December, and the beach is narrow and drops off quickly, so it's a place to sit rather than to swim.

  2. Taste2-3 hoursAbout 60-120 THB (2-3.50 USD) per street-food dish; cocktails from about 70 THB (2 USD)

    Friday Walking Street

    On Friday evenings from about 17:00 to 23:00 the village lane closes to traffic and fills with stalls: Pad Thai sizzling in woks, grilled skewers, tempura seafood, banana pancakes, and kanom krok, the small coconut rice pancakes cooked in a pan of round hollows. There's also Mango Sticky Rice for dessert, plus fabrics, jewelry and handmade goods. On Fridays a roundabout halfway down turns into a beer garden.

    Arrive by 17:30 or 18:00, before the queues build, and bring cash, because most stalls don't take cards. Prices are higher than at a mainland market, but the seafront is part of what you're paying for. Parking fills quickly, so take a taxi or songthaew instead of a scooter.

Day 2East coast

Day 2: Chaweng, Silver Beach and Lamai

This is the beach day, and the one to adjust if the weather turns. The whole east coast is one road, so it's an easy drive. The east-facing beaches catch the sunrise, not the sunset, and October to December is the wet season, so expect rain and murkier water then; January is the better bet. Chaweng and Lamai are the busy ones, so go early.

Morning
  1. Experience2-3 hoursFree; a sun lounger and drink about 100-300 THB (3-9 USD)

    Chaweng Beach

    Waves breaking on sand at Chaweng Noi, the northern end of Chaweng beach, with rocks at the shore

    Chaweng is the biggest, busiest and most commercial beach on Samui: about 7 km of powdery white sand, with a coral reef offshore where the waves break, so the bay itself is calm. Behind it is Samui's largest concentration of restaurants, shops, pubs and convenience stores. Until the early 1990s it was a sprinkle of wooden bungalows; today it's a resort strip where luxury hotels sit next to cheap guesthouses.

    The north end is quieter and the middle is crowded, and the beach is usually reached through hotels because there is no beach road. Vendors sell fruit, coconuts and satay, most small items around 50 THB (1.50 USD). Go in the morning, when the sand is empty and the sun isn't brutal. If you want nightlife, this is the place: the bars and clubs of Soi Green Mango and Soi Reggae officially close at 01:00, though in practice it's somewhere between 01:00 and 02:00 and the police are strict about it.

Afternoon
  1. Taste1 hourAbout 150-350 THB (4.50-10 USD) per person

    Southern Thai lunch in Chaweng

    When the Michelin Guide first covered Samui in 2024, it picked out a few places that cook southern Thai food, and one of them, Kapi Sator, is on Soi Had Chaweng 5, off the ring road, with listed hours of 10:00-22:00. The menu changes with the catch. Order local squid in a sweet coconut-milk soup with lemongrass, or deep-fried pomfret with a spicy southern curry on top. Both show the style: coconut, chili, fresh fish, and a lot of heat.

    If it's closed or full, look for a place where Thai families are eating, with a menu in Thai as well as English. Southern Thai food is hot. If you want less heat, ask for mai phet (not spicy). Order a Green Curry and Som Tam alongside, to compare the local style with the national classics.

    Silver Beach (Crystal Bay)

    Between Chaweng and Lamai, just before the ring road climbs a hill, is a small cove that's often called the best swimming beach on Samui. Its proper name is Hat Thongtakian, but everyone calls it Silver Beach or Crystal Bay after the two resorts at its end. The water is clearer and the beach quieter than at Chaweng or Lamai, and there are only a few places to stay and eat.

    It's a good place to do nothing for a few hours between the two big beaches. It's quiet, so bring water and snacks in case the few places there are closed. If you only swim at one beach on the island, make it this one. The sea is still the Gulf, so it's best on a calm day without wind from the east.

    Lamai Beach

    Lamai is Samui's second beach and a different place from Chaweng: smaller and a little rougher. The widest sand is in the southern third, close to the town, where loungers and jet-ski hire fill the beach; it has the best swimming but also strong waves and occasional rip currents, so watch for the flags. The northern end is quieter, with resorts and small restaurants, and a lagoon behind the sand.

    Lamai Beach Road is the nightlife strip, and it leans toward go-go bars, bikers and beach lounges rather than clubs. Pick your stretch: the south for activity, the north for calm. Old Lamai in the north has small French, German and Italian restaurants as well as Thai ones.

    At the south end of Lamai Beach are two weathered granite rocks that look exactly like what the Thais say they look like: male and female anatomy. They're called Hin Ta and Hin Yai, the Grandfather and Grandmother rocks, and they're one of the island's biggest attractions.

    The legend says an elderly couple, Ta Kreng and Yai Riem, sailed with their son to ask for a bride from a family in Prachuap Khiri Khan, but a storm sank their boat. In one version their bodies washed ashore and turned to stone; in another the gods did it. The rocks are slippery after rain, and there is a drop onto sharp stone if you climb for a photograph. Stalls along the path sell drinks and snacks. The light is better and the crowd smaller around 08:30 to 09:00, so if you're staying in Lamai, walk down first thing.

Evening
  1. Taste1.5 hoursAbout 300-500 THB (9-15 USD) per person

    Seafood dinner in Lamai

    Sabeinglae is a seafood restaurant on the ring road near Hin Ta Hin Yai, listed by Michelin in 2024 with hours of about 10:00 to 22:00, and known for local dishes such as mussels with glass noodles and ginger. It's also a simple model for how to eat seafood on Samui: choose the fish, agree how it's cooked, and ask for the weight and price before it goes on the grill.

    Seafood is priced by weight or species and it's where bills get big, so check the price first. In high season demand often exceeds local supply, which is another reason to order what's fresh that day rather than what you came for.

Day 3South and the hills

Day 3: The mummy, waterfalls and the Secret Buddha Garden

The south of Samui is where the island still looks lived in: a small fishing village at Hua Thanon, farmland, and the central hills. The roads are fine, but they climb, and the waterfalls and the Secret Buddha Garden are reached by short steep paths, so wear shoes with grip. Waterfalls are strongest after rain; in January they're lower than in November but still running.

Morning
  1. Taste1 hourAbout 30-120 THB (1-3.50 USD) per item

    Hua Thanon morning market

    Hua Thanon is a small fishing village on the south-east coast, and its market is a good place for breakfast the way locals eat it. It's a morning affair, so check the hours locally. Look for khao yam, the southern herbal rice salad with toasted coconut, and roti with curry for about 30-50 THB (1-1.50 USD).

    Southern Thai cooking is spicy and coconut-heavy, with Malay and Indian influences, and you'll find curries you won't see on a Bangkok menu. Kaeng tai pla (a curry made with fermented fish innards) isn't available every day and it's strong: order a small serving if you find it. For a milder start, try a coconut-based Green Curry and ask how spicy it is.

    Wat Khunaram and the mummy monk

    Photo: Roma Neus, CC BY 3.0

    Wat Khunaram is the island's most famous temple for one reason: the body of the monk Luang Pho Daeng, sitting upright in a glass case. He was born on the island in 1894, raised a family, ran a successful business and at 50 became a monk, known as a meditation master. When he felt death approaching he gave instructions that his body should not decompose, and he died meditating in 1973. Luang Pho Daeng hoped to self-mummify, but that didn't fully work, so others preserved the body and built the glass coffin he had asked for.

    Look closely and you'll see sunglasses on the face: the eyes rotted, and the monks covered the sockets. Some people suspect a wax figure, but researchers who X-rayed it in 2002 found the organs still in place, shrunken by dehydration. Wat Khunaram is a working temple, so dress properly, speak quietly and don't treat it as a freak show. Devotees leave flowers and incense.

    On the southern tip of the island, the pagoda at Wat Laem Sor is one of the most important shrines on Samui. The chedi (the bell-shaped Buddhist monument) is covered in yellow tiles that give off a golden glow, and it stands near the sea at the end of the south coast road.

    It's a short drive south from Wat Khunaram, so take it before heading up into the hills for the waterfalls. Dress modestly and take off your shoes before entering any hall.

    Na Muang Waterfalls

    The Na Muang Waterfall pair is the best-known on the island. Na Muang 1 drops around 18 meters into a natural pool, a five-minute walk from the car park, and you can swim in it. Na Muang 2 is further up, a steep hike of 20-35 minutes, with purple-tinted rocks around a much higher fall, listed at about 79 meters. Hin Lat Waterfall, inland from Nathon, is the quieter alternative (day five).

    Tour groups often pair the falls with the Secret Buddha Garden, so go early or late, and wear proper shoes, because the climb to Na Muang 2 is rough and wet. Flow is strongest in the wet months (sources say October to January), so in January or February expect lower water but calmer pools. Some sources mention a small fee at Na Muang 2; recent reviews say it's free, so be skeptical of anyone demanding an unofficial one on the path.

    Secret Buddha Garden

    Up a steep side road in the hills above Na Muang is the Secret Buddha Garden, also called Tarnim Magic Garden. In 1976 a local fruit farmer named Nim Thongsuk, then 77, started sculpting on his durian farm: human figures, animals and deities, Buddhist statues and little temples, scattered through the jungle. There's a pond with a bridge, shrines up the hill and a statue at the top above the canopy.

    It's an eccentric, slightly overgrown place, and that is its charm. Treat the Buddha images with respect and dress modestly. The final stretch of road is a rough dirt track and the walk up is short but steep, so ride a scooter only if you're experienced, and take a taxi or tour if you aren't. Hours are roughly 09:00 to 17:00 or 18:00.

Evening
  1. Experience1.5 hoursFree; a drink at a beach bar from about 100 THB (3 USD)

    Sunset at Taling Ngam

    Samui's east coast faces the sunrise, so the sunsets are on the west, where the beaches are still comparatively quiet. Taling Ngam, on the south-west coast, is a bay with a few resorts and restaurants and far fewer people than Chaweng. Don't plan on swimming; the sky is what you came for.

    Get there 30-45 minutes before sunset, which in January is a little after 18:00, and find a table facing west. Beachfront places cost more than a roadside restaurant, but a drink and a view are worth it once. Plan your ride home in advance: songthaews thin out in the evening and taxis charge what you agree.

Day 4Mu Ko Ang Thong National ParkDay trip

Day 4: Ang Thong Marine Park

The boat is the day. Ang Thong is open only through licensed operators, the park is closed from about 1 November to 15 December (so it's open in January), and the park fee (300 THB, about 9 USD) is paid separately in cash. Check what your tour price includes. If the sea is rough, boats are cancelled, so swap this day with day five if you need to.

    Mu Ko Ang Thong National Park was set up in 1980 and covers 42 islands, a mix of sheer limestone cliffs, beaches and lagoons 30-40 km from Samui. Ko Wua Talap is where the park headquarters are and most boats land. The main walk is the viewpoint above the headquarters: a steep, rope-assisted trail of about 500 meters, 25-30 minutes up, with a view over the island chain at the top.

    Wear shoes with grip, not flip-flops, and bring water. If your tour gives you limited time on the island, do this first, before the heat.

    Thale Nai, usually called the Emerald Lake, is a saltwater lake on Ko Mae Ko, enclosed by cliffs and connected to the sea by underwater caves. A trail of about 20 minutes leads up to a viewpoint above the lake. The color is the point.

    Boats from many operators stop here, so be patient at the viewpoint and give other people room for their photos.

    Lunch is the middle of the tour, and many operators serve a Thai buffet or a set meal, on board or at the restaurant on Ao Phi beach on Ko Wua Talap, where the park headquarters also has a small shop. Check whether lunch is included in your tour price. Some cheaper tours exclude it, and the park fee is separate in any case, so bring 300 THB per adult in cash.

    Kayaking and snorkeling

    The active part of the day is kayaking among the limestone islands and snorkeling at a reef; which island depends on the operator. Ko Sam Sao has beaches and a coral reef but no shops or restaurants. Most speedboat tours include a kayak, though some charge extra, and the snorkeling is decent rather than Maldives-quality.

    Gulf seas in January are less predictable, so visibility can be hit or miss, especially after rain. Wear a rash guard and reef-safe sunscreen. Boats return in the late afternoon.

Day 5Mae Nam, Hin Lat, Nathon

Day 5: Mae Nam, Nathon and the north-west

After a boat day, the last day is the slow one: the north-west of the island is quieter than the east and has less to see, and that's why it works as a rest day. You finish at Nathon, the island's port, where the ferries from the mainland arrive.

    Mae Nam is a quiet beach on the north coast, decent for swimming and sunbathing, and good for families with small children because the water is shallow. It's a calmer base than Chaweng, with a village behind the sand.

    There's little to do but swim, walk and eat, and that's the point of the morning. A Thursday evening walking street here may no longer run, so don't plan around it.

    Bang Por, on the north-west shore, has a row of seafood places on the sand. Bang Por Seafood Takho is one of them, in the 2024 Michelin Guide with listed hours of 10:00 to 22:00 daily, so confirm it's open. Order steamed sea bass with lime and chili, pla kapong neung manow, about 350-500 THB (10.50-15 USD).

    Wear shoes with grip, because the rocks are slippery. In January the water is lower than in the rainy season, so the cascades are smaller. Ban Lipa Yai, a village in the same area, grows rambutan, durian, mangosteen and langsat, so if there's fruit on a stall, stop.

    Nathon is Samui's port and administrative center, on the west coast, where the ferries from the mainland arrive. It's a working town, not a resort, and there isn't much to see, which is the honest verdict. What it gives you is the island without the beach industry: ordinary shops, the pier and people going about their day.

    Walk the seafront and watch the ferries come in. Hotel rooms here are the cheapest on the island (from around 400 THB, 12 USD, in older listings), which makes it a base only if budget beats beach.

    Nathon night food market

    By the ferry area in Nathon, a night food market sets up in the afternoon and evening (listings say it runs until about 22:00), serving local people rather than visitors. Expect grilled skewers, fried chicken, Som Tam, stir-fries and sausages. Vendors vary from night to night, so treat it as a place to graze rather than a fixed menu.

    This is a good last dinner: cheap, local and unpretentious. Som tam in the south is often made with fermented crab and dried shrimp, and costs around 50-70 THB (1.50-2 USD). Bring cash.

Koh Phangan and the Full Moon Party

Koh Phangan is the quieter neighbor, with its main town at Thong Sala, and it's where the Full Moon Party has run on Haad Rin beach since the 1980s. Be honest with yourself about it: it's a loud, all-night beach rave with 10,000 to 30,000 people. Entry is 200 THB (6 USD) in cash at the gate (online advance tickets are a scam), buckets of drink cost around 100-250 THB (3-7.50 USD), and drink spiking, theft from rooms, broken glass and drownings are real. Undercover police work the party and drug penalties are severe. It falls on the night of the full moon, or a night later if a Buddhist holy day lands on it; the January 2027 one falls on the full moon, Friday 22 January, but the local organizers confirm dates late, so check. Regular ferries from Samui run by day, so most people use party boats booked through an agent, and prices vary. Without the party, Phangan is a calm day trip: King Chulalongkorn visited it 14 times, and there is more to it than Haad Rin.

Getting there: 12-16 km north across the strait: about 30-50 minutes by ferry or speedboat from Bang Rak, Mae Nam or Nathon to Thong Sala

Don Sak and Surat Thani

Most visitors who arrive by ferry see Don Sak for ten minutes. It's worth a proper stop for one reason: seafood. Pa Ting is a seafood restaurant that opened in 1967 and is run by the founder's daughter, and the Michelin Guide has picked it out. Surat Thani, the nearest big city, is the mainland's transport hub, with a train station and an airport. If you leave by ferry with hours to spare, eat here before you go.

Getting there: About 40 km west across the Gulf to Don Sak on the mainland; car ferries run from Nathon and Lipa Noi, and the crossing takes about 90 minutes

Koh Tao

Ko Tao, the Turtle Island, is the diving capital of the Gulf: about 21 square km, 100,000 or more visitors a year, and dive shops everywhere. If you want to learn to dive, base yourself here rather than on Samui, where the water is silty. Many tours from Samui combine Ko Tao with Nang Yuan in one long day. Peak seasons on Tao are December to March and July to August, and rough seas can cancel boats from late October into January, so keep a spare day.

Getting there: About 60 km north-west: 1.5-2 hours by catamaran from Mae Nam or Bang Rak (Lomprayah and others), or a day tour by speedboat

Koh Nang Yuan

Koh Nang Yuan is a group of small islands joined by a sandbar, just off Ko Tao, and the postcard picture of the Gulf. The entry fee is paid in cash and reported anywhere between 100 and 250 THB (3-7.50 USD), so check on the day; there are no ATMs. The viewpoint hike takes 15-25 minutes and involves scrambling over granite. The reef by the sandbar suits beginners, and blacktip reef sharks turn up in the deeper channels. Go early, before the day-tour boats from Samui and Ko Tao arrive. Tours from Samui covering Koh Tao and Nang Yuan often leave out the island fee.

Getting there: About 70 km north-west of Samui, 10-15 minutes by longtail from Ko Tao; the Samui tour boats take around 2 hours each way

Khao Sok National Park

Khao Sok is a different Thailand: 739 square km of virgin rainforest, limestone cliffs and Cheow Lan Lake, with raft houses you reach by longtail boat. Entry is 200 THB (6 USD) for the headquarters area and 300 THB (9 USD) for the lake, paid separately. The wet season runs from late April to December, so January is among the better months. Wildlife includes elephants, tapirs and white-handed gibbons. It's too far for a day trip from Samui, so treat it as an overnight.

Getting there: About 220 km from Samui by ferry and road: the ferry to Don Sak, then a drive of roughly 3 hours; plan an overnight

Experience

Sail Rock

Sail Rock (Hin Bai) is a granite pinnacle that serious divers and freedivers travel for: a famous vertical chimney you swim through, plus the occasional whale shark, reported mostly from March to May, so don't count on one in January. It's not for beginners, and the late-October to January monsoon seas can cancel trips.

Getting there: Between Ko Tao and Ko Phangan, reached by dive boats from Samui, Phangan or Ko Tao, a half-day or full-day trip

What to Eat and Drink in Koh Samui

Samui eats southern Thai: hotter than Bangkok, heavy on coconut and seafood, with Malay and Indian influences. Here are the five national classics, then the southern dishes worth hunting for.

Pad Thai

Stir-fried rice noodles with shrimp or chicken, egg, tofu, peanuts and tamarind sauce, cooked in a big wok. It's the dish you'll see at every market, and it's best when you watch it being made. Season it at the table.

Where to try it: Street stalls at the Fisherman's Village Friday walking street and the Nathon night market, for about 60-100 THB (2-3 USD).

Green Curry

A coconut curry with Thai basil, bamboo shoots and green chilies, eaten over rice. With chicken, fish or seafood, it's on almost every menu on the island. Southern curries are hotter than the Bangkok kind, so say so if you want it milder.

Where to try it: Any local Thai restaurant at lunch, usually around 80-150 THB (2.50-4.50 USD); around Hua Thanon, look for coconut curries at the morning market.

Som Tam

Green papaya salad pounded in a clay mortar with chilies, lime, fish sauce and peanuts. It comes from Isaan, in the north-east, but you'll find it everywhere, and the southern version often uses fermented crab (pu dong) and dried shrimp. Say mai phet to tone it down.

Where to try it: Nathon night market and roadside stalls, about 50-70 THB (1.50-2 USD).

Tom Yum Goong

Hot and sour shrimp soup with lemongrass, galangal, kaffir lime and chilies. There are two styles, clear and creamy. On an island with this much seafood, order it with prawns.

Where to try it: Seafood restaurants at Bang Rak, Bang Por and Lamai, roughly 150-300 THB (4.50-9 USD).

Mango Sticky Rice

Ripe mango slices over glutinous rice sweetened with coconut milk, usually with a salty-sweet coconut cream on top. The best versions come in mango season (roughly March to May); in January it's still good.

Where to try it: Walking street stalls and night markets, around 80-120 THB (2.50-3.50 USD).

Southern curries

Gaeng som is a sharp, sour fish curry with local vegetables, massaman is the mild peanut curry with Indian-Muslim influence, and kaeng tai pla is the fermented-fish-innards curry that only the brave will love. Indian-style chicken biryani is also a southern favorite. These are the dishes locals eat for lunch.

Where to try it: Hua Thanon morning market and Nathon's local eateries; ask what the dish of the day is.

Coconut

Samui is known for its coconuts, and they're sold everywhere: a cold young coconut is the best drink on a hot afternoon, and the milk goes into curries, soups like tom kha gai (chicken with galangal in coconut milk) and desserts such as kanom krok, the coconut rice pancakes.

Where to try it: Beach vendors, markets and any street corner; the soup is on most restaurant menus at around 80-120 THB (2.50-3.50 USD).

Roti with curry

A flaky fried roti, torn and dipped in curry, is a southern breakfast with Indian roots. At Hua Thanon's morning market it costs about 30-50 THB (1-1.50 USD).

Where to try it: Hua Thanon morning market.

Khanom jeen

Thin rice noodles served with a spicy green or yellow curry and a plate of raw vegetables and herbs, eaten in the south at breakfast and lunch. Vendors cook it to order in seconds.

Where to try it: Morning markets such as Hua Thanon's, and local cafรฉs along the ring road near Lamai; ask for it by name.

Steamed fish and squid

Seafood is what Samui does for dinner. Steamed sea bass with lime and chili (pla kapong neung manow), stir-fried squid with pineapple, squid in sweet coconut-milk soup with lemongrass, and mussels with glass noodles and ginger. Prices are by weight or species, so ask first.

Where to try it: Bang Por Seafood Takho, Sabeinglae in Lamai, Kapi Sator in Chaweng; check they are open before going.

Thai beer and Samui rum

Singha, Chang, Tiger and Leo are the local beers; they cost around 90 THB (2.70 USD) in a basic bar and more in a resort. Wine is expensive on Samui (often over 2,000 THB, about 60 USD, a bottle), so drink beer. There's also a sugar-cane rum distillery on the south coast, with free samples.

Where to try it: Convenience stores sell beer between 11:00 and midnight; restaurants and bars serve it any time. Alcohol is not sold on some Buddhist holidays.

Where to Stay in Koh Samui

You'll spend nights in a beach base, and which one decides the trip. Pick by what you want from the evening, not the day: all the sights are 15-45 minutes by car.

Chaweng

Best for: Nightlife, restaurants, shops and a long beach, first-timers who want everything within reach

Sea
A coral reef offshore breaks the waves, so the bay is usually calm. About 7 km of east-coast sand; Oct-Dec is wet, January better.
Beach
Powdery white sand, crowded in the middle and quieter in the north; most of it is reached through hotels, not a beach road.
Evenings
Samui's biggest nightlife: beer bars on Soi Reggae, clubs around Soi Green Mango. Bars are supposed to close at 01:00.
Shops
Central Festival mall, Tops and Lotus's go fresh supermarkets, 7-Eleven and FamilyMart, pharmacies and ATMs along the beach road.

Chaweng is the heart of the island and the easiest base, with the biggest choice of food, shops and tour pick-ups. The catch is the noise: the best beach hotels in the north are close to the nightclub area, so book Chaweng Noi or a quieter stretch if you want to sleep.

Lamai

Best for: A cheaper, more relaxed beach town with rough edges, travelers who like a local feel

Sea
Open bay; the southern third swims best but has strong waves and occasional rip currents. Check the flags.
Beach
Widest sand in the south, full of loungers; narrower and rockier toward the northern headland, with a lagoon behind.
Evenings
Bars and go-go bars in the south on Lamai Beach Road; the northern end is calmer, with small restaurants.
Shops
Lotus's and Tops supermarkets, Big C Mini, 7-Eleven and FamilyMart, many pharmacies and ATMs on the beach road.

Lamai is Chaweng's smaller sibling: less polished, a bit cheaper and closer to the south's sights (Hin Ta Hin Yai, Wat Khunaram, Na Muang). The catch is the beach, which has stronger waves and rip currents than Chaweng, and a nightlife strip that's rough in the south. Stay in the northern half if you want calm.

Bophut

Best for: Couples and families who want good restaurants and a village feel, not a party

Sea
Calm, sheltered bay, but the water is often murky, especially around December. The beach is narrow and drops off quickly.
Beach
About 2 km of white sand fringed by palms; a place to sit and watch the sunset rather than swim.
Evenings
Fisherman's Village: about 30 bars and restaurants in 700 m, a Friday walking street and no go-go bars.
Shops
Big C and Lotus's go fresh, 7-Eleven and FamilyMart, pharmacies and ATMs on the ring road; boutiques in the village.

Bophut, around Fisherman's Village, is the best base for this plan: 15 minutes from the airport, close to the Big Buddha, ferries to Koh Phangan and Koh Tao, and the Ang Thong boats. The catch is the beach, which is narrow and often murky, and the village gets crowded on Friday evenings, so pick a room a few minutes off the main lane.

Choeng Mon

Best for: Quiet, family-friendly stays with a calm bay, travelers who don't need nightlife

Sea
A small, sheltered bay: calm and clean. With an east wind it gets choppy and snorkeling visibility drops.
Beach
A crescent of wide white sand about 500 m long, with a rocky end and the Ko Fan islets you can kayak or wade to.
Evenings
Quiet: resort restaurants and beach bars, some with Thai dance shows or live covers. Nothing like Chaweng.
Shops
A few 7-Eleven, FamilyMart and Tops Daily stores and one pharmacy on the main road; big supermarkets are in Chaweng or Bophut.

Choeng Mon is the quiet corner: a handful of upscale resorts and a family-friendly beach, 15 minutes from the airport. The catch is the cost and the isolation: cheap rooms are scarce, there's little to do outside the resorts, and songthaews are rare, so plan on Grab or a rental.

Before You Go

The practical stuff that makes the first day in Koh Samui easier.

Visa and TDAC

US citizens can enter without a visa for tourism, but from 15 September 2026 the visa-free stay is 30 days, not 60, as the Royal Thai Embassy in Washington explains. It can be extended for up to 30 days, solely at the immigration officer's discretion. Everyone must also fill in the free Thailand Digital Arrival Card at tdac.immigration.go.th within the 3 days before arrival; avoid fake paid sites. The embassy also lists a rule of 20,000 THB in cash per person, which is rarely checked, and your passport must be valid.

Money

Thailand uses the baht (THB), about 33 per US dollar in October 2026. Cards work in hotels and bigger restaurants, but cash is needed at markets, street stalls, songthaews and the national park. ATMs are everywhere and usually dispense up to 20,000 THB at a time; check the fee on screen before you accept. Tipping isn't expected: round up, and never give more than about 50 THB. Some places have two menus, one for tourists and a cheaper one for locals, so check prices before you order.

Getting around

By day, songthaews (pickup-truck buses) run fixed routes at roughly 20-80 THB (0.60-2.40 USD) a person by day; in the evening they act as taxis and the price is yours to negotiate. Taxi drivers rarely use the meter, so agree the fare first or use Grab. Scooters rent for about 120-700 THB (4-21 USD) a day, but accidents are common, the rental insurance often isn't real, and shops that ask for your passport as a deposit are a risk: don't leave it. A small car is about 1,200-1,500 THB (36-45 USD) a day. Thailand drives on the left.

Season and sea

The Gulf has its own calendar. Most of Thailand, Phuket included, has its monsoon from April to September, when Samui stays fairly dry. Samui is wet from mid-October to early December, with November the heaviest (about 445 mm). January is still damp (about 127 mm) and February is the driest month (about 64 mm). Seas can be rough in the wet months, and boats to Ang Thong, Koh Tao and Koh Phangan get cancelled when they are, so keep a spare day.

Temples and dress

Cover your shoulders and knees in any temple, take your shoes off before entering a hall, and don't point your feet at a Buddha image or climb on statues. Insulting the royal family is a serious crime in Thailand, so keep opinions to yourself. Vapes and e-cigarettes are illegal, even in your bag.

Alcohol and nights out

Supermarkets and chain convenience stores sell alcohol between 11:00 and midnight; bars and restaurants aren't affected. Sales are banned on some Buddhist holidays, which can also move the Full Moon Party (Makha Bucha, 21 February 2027, moves it by a day). Entertainment zones are supposed to close at 01:00, and the police take it seriously. Drugs carry severe penalties.

Scams and traps

At the airport, people with hotel signs may offer a free taxi if you attend a timeshare presentation. Don't drink tap water. Keep valuables out of checked bags on bus-and-ferry combinations, where thefts have been reported. Rental shops sometimes claim damage that was already there, so photograph the bike before you ride.

Phone, data and plugs

Samui Airport has SIM booths for AIS and True (DTAC is now part of True); bring your passport to register. Thailand runs on 220 V, 50 Hz and most outlets take the flat two-pin plugs used in North America, but 120 V-only appliances will overheat, so check your charger says 100-240 V. Tourist police: dial 1155.

Koh Samui Travel FAQ

Is 5 days enough for Koh Samui?

Yes. Five days covers the main sights, a day at Ang Thong Marine Park and a rest day. If you want Koh Tao, Koh Phangan or Khao Sok as well, add a day for each.

When is the best time to visit Koh Samui?

January and February, when it is dry and slightly cooler; February is the driest month (about 64 mm of rain). The Gulf's rainy season runs mainly from mid-October to early December, with November the wettest at about 445 mm. That is out of step with most of Thailand, which has its monsoon from April to September. January still gets about 127 mm and can have rough seas.

Do US citizens need a visa for Thailand?

Not for tourism: US citizens can enter visa-free. From 15 September 2026 the stay is 30 days (it was 60), with one extension of up to 30 days possible at a local immigration office. You must also complete the free Thailand Digital Arrival Card online at tdac.immigration.go.th before you arrive. Rules change, so check the Thai embassy site before you fly.

How do I get to Koh Samui?

Fly into Samui Airport (USM), which Bangkok Airways built and runs, with near-hourly flights from Bangkok. Fares are high for the distance, often roughly 75-150 USD one way. The cheaper option is to fly to Surat Thani (URT) and take a bus-and-ferry combination via Don Sak to Nathon; the Seatran crossing alone is about 1.5 hours and resellers list it from around 190 THB (6 USD). Lomprayah also sails from Ko Tao and Ko Phangan.

Is the Full Moon Party worth it?

Only if you want a huge, loud, all-night beach party. It draws roughly 10,000 to 30,000 people on Haad Rin beach on Koh Phangan, costs 200 THB (6 USD) to enter, and comes with drink spiking, theft and heavy police presence. Watch your drinks, lock valuables in the room safe and stay away from drugs.

What is the best day trip from Koh Samui?

Ang Thong Marine Park, which is day four in this plan: 42 limestone islands, the Wua Talap viewpoint, the Emerald Lake and kayaking. It's open in January (it closes from about 1 November to 15 December). For snorkeling and diving, Koh Tao and Koh Nang Yuan are the other classic trip.

Is Koh Samui expensive?

More than the mainland. Street food is 50-120 THB (1.50-3.50 USD) a dish and a seafood dinner 300-500 THB (9-15 USD), but flights, resort rooms and beachfront restaurants cost far more. Plan on roughly 75-135 USD a day on top of the room.

Where should I stay on Koh Samui?

Chaweng for nightlife and the biggest choice, Lamai for a cheaper and rougher beach town, Bophut for restaurants and a village feel, Choeng Mon for a quiet bay. For this plan, Bophut or Chaweng works best, since both are close to the airport and the northern sights.
