7 Biggest Carnivals in the World - Attendance and 2027 Dates

There's something about a carnival that turns an entire city inside out. Streets that are normally gridlocked with commuters become stages for dancers in feathered costumes. Public squares where people usually rush past each other with headphones in suddenly fill with drums, brass bands, and strangers dancing together like they've known each other for years. Carnivals are one of those rare things that pretty much every culture on Earth has some version of - a moment where the rules relax, the music gets loud, and everyone collectively agrees to have a good time.

Some of these events have been running for centuries. Others are relatively new but have exploded in scale. What they all share is the ability to completely transform a city for days or even weeks. Here are seven of the biggest and most iconic carnivals on the planet.

So which carnival is the biggest? Rio de Janeiro. Its Carnival is the one most lists crown, with about two million people a day on the streets, and the city expected 6.8 million people at its street parties alone in 2026. The one to argue about is Salvador, also in Brazil: the state security department counted about 12 million people over six days in 2026, and it's often called the world's largest street party (we couldn't find that title on Guinness's own site, only in second-hand sources). Those counts aren't comparable, because each city measures crowds its own way, so the honest ranking is Rio and Salvador at the top in either order, then everyone else a clear step down.

Salvador isn't one of the seven below, but it belongs in any ranking by headcount. Here's how the seven compare, with the latest crowd figure we could source and the 2027 dates as published so far (checked October 19, 2026). The pre-Lent carnivals all end by Ash Wednesday, which falls on February 10, 2027.

We found no official 2027 dates for Salvador yet, and the Rio dates come from the samba schools' league (Liesa) as reported by Brazilian media, so check before you book.

Rio de Janeiro Carnival - Brazil

You can't talk about carnivals without starting here. Rio's Carnival is the one most people mean by "the biggest" - around 2 million people per day hit the streets during the five-day event, and the city expected 6.8 million people at its street parties alone in 2026. It happens every year in the days leading up to Lent, usually in February or March.

The heart of it is the Sambadrome - a purpose-built parade ground designed by Oscar Niemeyer where the top samba schools compete against each other. Each school spends the entire year preparing a themed performance with thousands of dancers, massive floats, and original music. The competition is intense and taken very seriously. Schools move up and down between divisions, and the champion of the second tier goes straight up. Winning the championship is a source of enormous neighborhood pride, and losing can be genuinely devastating.

But the Sambadrome parades are just the official part. The real soul of Rio Carnival is in the "blocos" - street parties organized by local communities that pop up all over the city. There are hundreds of them (462 were authorized in 2026), from tiny neighborhood gatherings to massive ones that draw hundreds of thousands of people. Some are themed (the Sargento Pimenta bloco plays Beatles songs in samba and marchinha rhythms), and joining any of them costs nothing. You just show up and follow the music. If you're going in 2027, our Rio Carnival 2027 planner has the parade order night by night, Sambadrome ticket prices and the bloco calendar.

Venice Carnival - Italy

If Rio is raw energy and sweat, Venice is its elegant opposite. The Venice Carnival is all about mystery, masks, and a city that already feels like it exists outside of normal time. It goes back to the Middle Ages, was outlawed in 1797 when the Republic of Venice fell, and was revived in 1979 as part of a push to restore the city's history and culture. It worked - about 3 million visitors now show up every year.

The masks are the thing. Venetian masks have a history that goes way beyond costume parties. In the old Republic of Venice, masks could be worn for months at a time - from December 26 to Shrove Tuesday, and on other occasions too - and a nobleman and a commoner looked alike behind one. The tradition gave birth to an entire artisan craft, and the mask shops scattered around Venice today still sell handmade works.

The modern carnival runs for roughly two and a half weeks (2027: January 23 to February 9) and people gather around Piazza San Marco. There's no parade route or formal competition like Rio. Instead, people in elaborate costumes simply appear in the squares and along the canals, posing for photos and creating scenes that look like something from an 18th-century painting. The best costume wins a prize, but honestly, the real spectacle is just walking through the city and turning a corner to find someone in a full baroque gown standing next to a gondola.

Trinidad and Tobago Carnival

If you ask Caribbean people which carnival is the best, a lot of them won't say Rio - they'll say Trinidad. And they have a point. Trinidad is where calypso developed, where the steelpan (built from oil drums) appeared in the 1930s, and where soca was created in the 1970s. The musical innovation that comes out of this tiny two-island nation is honestly kind of insane relative to its size.

The street parade runs on the Monday and Tuesday before Ash Wednesday (February 8 and 9 in 2027). It starts with "J'ouvert" (from the French for "break of day") in the early hours of Monday, where crowds covered in paint, mud, chocolate, or oil dance through the streets in the dark. It's deliberately messy and chaotic - the opposite of the polished costumes that come later. By Tuesday, the "pretty mas" takes over with massive costume bands parading through Port of Spain in elaborate, brightly colored outfits.

What makes Trinidad special is that everyone participates. This isn't a spectator event where you watch from the sidewalk. You join a band, you get a costume, you're in the parade. The roots go back to the 1780s, when French planters held masquerade balls before Lent and the enslaved Africans they excluded staged their own mocking versions. After emancipation, freed people made the festival their own, and the authorities spent the 1880s trying to police it.

Notting Hill Carnival - London, England

The Notting Hill Carnival is Europe's biggest street festival - around 2 million people over the August bank holiday weekend - and it exists because of one of London's darker chapters. In the 1950s, Caribbean immigrants in the Notting Hill area faced violent racism, including the 1958 race riots. Trinidadian activist Claudia Jones organized the first indoor Caribbean carnival in 1959 as a response - a way to celebrate Caribbean culture and build community in a hostile environment.

The first outdoor event in Notting Hill was in 1966, and it grew from there. Today the parade takes over more than three miles of streets in West London, with sound systems, steel bands, calypso floats, and food stalls selling jerk chicken, curry goat, and fried plantain. The sound system culture is a big deal - operators set up massive speaker stacks on street corners and essentially run their own mini-festivals within the carnival, each playing different genres from dancehall to drum and bass to soca.

There's a quiet political undercurrent that never fully goes away. Notting Hill Carnival started as an act of cultural resistance, and for a lot of attendees - especially from the Caribbean community - it still carries that meaning. It's celebration and defiance in equal measure, which gives it an emotional weight that purely festive events don't always have.

Mardi Gras - New Orleans, USA

New Orleans' Mardi Gras is technically the entire season from Epiphany (January 6th) to Fat Tuesday, which means the city is in some state of carnival celebration for over a month (in 2027, January 6 to February 9). But the real intensity builds in the final two weeks, when parades roll along St. Charles Avenue and Canal Street almost daily.

The parades are organized by "krewes" - social clubs with names like Rex, Zulu, Endymion, and Bacchus. Each krewe builds its own floats and riders throw "throws" to the crowd - beads, doubloons, stuffed animals, cups. Catching a good throw is weirdly competitive. People bring ladders, build scaffolding, and shout themselves hoarse trying to get the attention of float riders. The Zulu club, a historically Black krewe, has thrown hand-painted coconuts since the late 1940s, and they're one of the most sought-after catches of the season.

What makes New Orleans Mardi Gras unique is its deep connection to the city's musical identity. Brass bands march through neighborhoods playing jazz and funk. Second line parades - where a band leads and everyone else follows, dancing with umbrellas and handkerchiefs - are part of the city's year-round music culture. The food is a whole event in itself: king cake (a cinnamon pastry with a tiny plastic baby hidden inside) is everywhere, and whoever finds the baby has to buy the next cake or host the next party. It's the kind of tradition that sounds absurd until you're three slices deep and genuinely nervous about biting into plastic.

Cologne Carnival - Germany

Germans don't have a reputation for being wild party people, which makes the Cologne Carnival all the more surprising. The "fifth season" (as locals call it) officially starts on November 11th at 11:11 AM and builds through the winter until the main events in the days before Lent. On Rose Monday alone, more than a million spectators line the parade route (organizers say around 1.4 million), and the entire Rhineland region essentially goes on holiday.

The key day is Weiberfastnacht (Women's Carnival Thursday), when women symbolically take over the city. The tradition involves women cutting men's ties with scissors - so if you're a guy wearing a tie in Cologne on that day, you're basically volunteering to lose it. The Rose Monday parade is the grand finale, an 8.5-kilometer route with about 12,000 participants and floats that are often sharply political. German carnival floats are famous for their satirical commentary - giant papier-mache caricatures of politicians doing embarrassing things are a staple, and nothing is off limits.

Beer consumption during Cologne Carnival is staggering. The local Kolsch beer - served in tiny 200ml glasses that waiters carry around on circular trays - flows nonstop for days. The carnival greeting is "Kolle Alaaf!" (roughly "Cologne above all!"), and you'll hear it approximately ten thousand times per hour. There's a real warmth to it though. Strangers buy each other drinks, everyone is in costume, and the usual German reserve completely disappears.

Barranquilla Carnival - Colombia

The Barranquilla Carnival is one of the biggest in Latin America, and arguably more culturally significant than its crowd numbers suggest. UNESCO declared it a Masterpiece of the Oral and Intangible Heritage of Humanity in 2003, recognizing it as one of the most important expressions of Colombian cultural identity. Organizers reported more than 6 million "spectators" in 2026, but that count includes broadcasts, so it can't be set next to Rio's street numbers.

The carnival is a collision of Indigenous, African, and European traditions that's uniquely Colombian. The cumbia music and dance that define it trace back to the meeting of enslaved Africans and Indigenous peoples on the Caribbean coast. The "Battle of the Flowers" parade opens the festival with floats covered in flowers, and the "Gran Parada" features traditional dances and costumes that have been passed down through generations - the Marimonda (a hooded figure with a long nose and floppy ears), the Congo dancers, and the Garabato (a dance that stages a battle between life and death).

The whole thing ends with the symbolic funeral of Joselito Carnaval - a figure who represents the spirit of the carnival itself. On the last day, people carry a "body" through the streets while mourners weep theatrically. It's funny and moving at the same time, and when Joselito is finally "buried," it means carnival is over and normal life resumes. Until next year, when he'll be resurrected and the whole thing starts again.

Why Carnivals Matter

Carnivals aren't just parties. They're pressure valves. Throughout history, they've served as the one time of year when social hierarchies get flipped, when the powerless get to mock the powerful, and when communities that are normally marginalized get to take center stage. That's why so many carnivals have roots in resistance - Trinidad's grew out of the masquerades of enslaved Africans and then of freed people, and Notting Hill's started a year after the 1958 race riots. Cologne's floats still carry on the tradition of mocking the powerful.

They're also incredible displays of what humans can create when they collaborate. The samba schools in Rio involve thousands of people working together for months. The steelpan orchestras in Trinidad turn literal garbage into music. The mask makers in Venice keep alive a craft that's been refined over centuries. There's a kind of collective creativity at work in carnivals that you don't see anywhere else.
