There's a moment at the top of a good viewpoint where the place you've been walking around for three days suddenly makes sense. The streets connect. The mountain you kept seeing between buildings turns out to be the edge of a whole range. Geography stops being an abstraction and becomes something you can point at.
Some of these views you earn with your legs, some you buy with a cable car ticket, and one of them requires getting up at four in the morning and being fine with a queue. They're spread across six continents, and I've tried to be specific about how you actually get to each one, because "go to Santorini" is not useful advice when 15,000 other people had the same thought that afternoon.
Table Mountain, South Africa

Cape Town is one of the few big cities with a 1,086 meter mountain in the middle of it, and the flat summit of Table Mountain gives you the entire peninsula at once: the city bowl, Robben Island out in the bay, the Twelve Apostles running south, and two oceans worth of weather arriving from different directions. The cable car cabins rotate as they climb, so you get the full panorama without fighting anyone for a window.
If you'd rather walk, Platteklip Gorge takes most people between 90 minutes and two and a half hours, straight up a rocky staircase with no shade. Check the webcam before committing to either option. When the "tablecloth" cloud pours over the rim, which happens constantly in summer, you'll pay for a view of the inside of a cloud. Lion's Head at sunset is the local answer on those days, and honestly it might be the better photograph anyway. More on South Africa if you're planning the rest of the trip.
Preikestolen, Norway

Pulpit Rock is a flat slab of granite hanging 604 meters above the Lysefjord with nothing between you and the water. No railing, no barrier, no attendant telling you to step back. It's about four kilometers each way from the car park, roughly two hours up, and the path is rocky rather than technical. Thousands of people do it every summer day in trainers.
Which is the problem. Go at seven in the morning or start at five in the evening, and you'll have something close to the experience the photos promise. Go at noon in July and you'll queue to stand on the edge. If you want the harder, emptier version, Kjeragbolten is a few fjords south: longer, steeper, and it ends with a boulder wedged in a crevasse that people insist on standing on.
Victoria Peak, Hong Kong

No other city stacks itself quite like Hong Kong, and the only way to understand the density is to get above it. The Peak Tram has been hauling people up the slope since 1888 at an angle steep enough that the buildings outside the window look like they're falling over.
Here's the tip that matters: skip the paid viewing terrace at the top and walk the Lugard Road loop instead. It's flat, it takes about half an hour, it's free, and the view is the one you've seen on postcards. Arrive around 45 minutes before sunset so you get the skyline in daylight, at dusk, and then lit up. The harbour light show runs at eight every evening if you want an excuse to stay.
Oia, Santorini

The reason Santorini looks the way it does is that most of the island exploded. The Minoan eruption around 1600 BC blew the center of the volcano into the sea and left a crescent of cliff standing 300 meters above a flooded crater. The white villages sit right on the lip of it, which is why every single photo of Greece that isn't a beach seems to be taken here.
And it is genuinely mobbed. Oia castle at sunset is a crush of people holding phones over each other's heads, with tour buses arriving 90 minutes beforehand. Two fixes: walk fifteen minutes along the caldera path away from the castle, where the same sun sets over the same water with a tenth of the crowd, or base yourself in Imerovigli and watch from Skaros Rock. Greece has plenty of islands with better beaches, but none of them look like this.
The Grand Canyon, United States

Nothing prepares you for the scale. The canyon runs 446 kilometers, drops more than 1,600 meters, and is wide enough that the far rim looks like a different landscape with different weather. Photographs flatten it completely. You need to stand there and watch a raven disappear into the gap to get any sense of the distance.
The South Rim is open all year and takes the overwhelming majority of the six million annual visitors. The North Rim gets about a tenth of them, is a thousand feet higher, and only opens from mid May until the snow closes it in October. For the version almost nobody sees, Toroweap has a 900 meter vertical drop straight to the river, reached by roughly 100 kilometers of dirt road that will eat a normal rental car.
Sugarloaf Mountain, Brazil

Rio's geography is the most theatrical of any big city on earth: granite domes shoved up between beaches, forest growing on vertical rock, and a bay full of islands. Sugarloaf is a 396 meter lump of granite at the mouth of Guanabara Bay, and the cable car has been running since 1912, which makes it one of the oldest in the world.
It goes in two stages, and the trick most people miss is that the first stop, Morro da Urca, is where you want to be at sunset. You get Copacabana on one side, the bay and Christ the Redeemer on the other, and the lights coming on across the whole city. Corcovado gives you the more famous statue, but Sugarloaf gives you the better view, partly because Corcovado is in it.
Gornergrat, Switzerland

Some viewpoints require suffering. This one requires a train ticket. A cog railway has been climbing from Zermatt to Gornergrat at 3,089 meters since 1898, and at the top you're looking at the Matterhorn, the Gorner glacier, and something like twenty peaks over 4,000 meters, all without getting out of breath.
Sit on the right hand side going up. Then walk down one stop to the Riffelsee, a small lake that reflects the Matterhorn perfectly on a calm morning, which is the photo everyone thinks requires a drone. Zermatt itself is car-free, so the whole thing runs on trains, electric buggies and your own legs. Switzerland has done this sort of infrastructure better than anyone.
Chureito Pagoda, Japan

This is the view of Japan that ends up on every poster: a red five storey pagoda in the foreground, the town of Fujiyoshida below, and Mount Fuji rising behind it as a nearly perfect cone. It costs 398 steps from the car park, which is a bargain by viewpoint standards.
The thing nobody mentions is that Fuji spends much of the summer hidden in haze. Clear views are far more likely between November and February, when the air is dry and the snow cap is at its best. Cherry blossom in mid April adds pink to the frame and adds a crowd to match. Early morning, any season, is the honest answer. Japan rewards being awake at six.
Roys Peak, New Zealand

The South Island is full of viewpoints you can drive to. This one you have to earn: 16 kilometers return, about 1,200 meters of ascent, five to six hours of zigzagging up a grassy face with sheep watching you. What you get at the top is Lake Wanaka spread out below with Mount Aspiring and the Southern Alps behind it.
Two practical notes. The famous photo spot on the ridge is not the summit, it's about 20 minutes below it, and in summer there's a queue of people waiting their turn to stand on it. The track also closes for lambing from the start of October to around the tenth of November, which catches out a lot of visitors to New Zealand arriving in spring.
The Sun Gate, Machu Picchu, Peru

Most people see Machu Picchu from the classic terrace viewpoint inside the site, which is excellent. The better version is Inti Punku, the Sun Gate, about an hour's walk up the old Inca Trail from the ruins. It's the notch in the ridge that trekkers come through after four days of walking, and it was built so that the sun lines up with it at the June solstice.
From up there the whole site sits below you with Huayna Picchu behind it and cloud forest dropping away on both sides. Go early, before the mist burns off, because watching the ruins appear and disappear is better than seeing them in flat midday light. Entry to the site is by timed ticket on fixed circuits now, so check which circuit includes the Sun Gate when you book rather than showing up and hoping. Peru does not make this easy to improvise.
How Not to Waste a Good Viewpoint
A few things I've learned the expensive way. Go at the edges of the day, because midday light is flat and midday crowds are the worst of it. Check a webcam or a mountain forecast before you commit to a cable car ticket, since summits make their own weather and the valley below tells you nothing. Build a spare day into the plan for anything weather dependent, because one look at the inside of a cloud is a story and two is a wasted trip.
And put the phone away for the first five minutes. Your eyes handle the contrast between a dark valley and a bright sky far better than any camera, and the photo will still be there once you've actually looked at the thing.
Find Them on a Map First
Half the pleasure of a view like this is knowing what you're looking at: which range, which ocean, which country starts on the other side of that ridge. That's a skill you can build in a few minutes a day.
Pinpoint drops you on a blank map and asks you to click the country, which is harder and more useful than it sounds. Memory Map works region by region if you'd rather build it up slowly, and Geo Quiz covers the mountains, rivers and landmarks behind most of these views.
