London is one of those cities that never really runs out of things to do. You can spend a weekend doing nothing but the classic tourist trail and have an amazing time. Or you can skip most of it and find something entirely unexpected, a neon-lit wonderland in East London, an immersive art space with no straight walls, or a climb across the roof of an arena.
This guide covers seven of the best fun attractions in London, split by type so you can plan around your interests and how much you want to spend. From iconic landmarks to off-the-radar picks, there's something here for first-timers and repeat visitors alike.
1. The London Eye
The London Eye towers above the Palace of Westminster and Big Ben in London
There's a reason the London Eye shows up in every photo of the city's skyline. This 135-meter observation wheel on the South Bank gives you a slow, 360-degree view of central London from a glass capsule, and on a clear day, you can see as far as Windsor Castle. It's one of those fun things to do in London that earns its reputation.
Each rotation takes about 30 minutes, which is a lot of time to spot Big Ben, the Houses of Parliament, St. Paul's Cathedral, and the Shard all at once. Book a London Eye ticket in advance to skip the line; it fills up fast, especially on weekends and school holidays.
Klook Tip: Visit at sunset for the best light and a memorable view over the Thames.
2. Warner Bros. Studio Tour London — The Making of Harry Potter
The iconic Hogwarts Castle model is illuminated inside Warner Bros. Studio Tour London
If you grew up reading books or watching movies, this is one of the most fun attractions to do in London. The Warner Bros. Studio Tour London takes you behind the scenes of the Harry Potter movies, with original sets, costumes, and props spread across a massive purpose-built complex just outside the city.
You'll walk through the actual Great Hall, step onto Platform 9¾, and see creatures from the Forbidden Forest up close. It's easily one of the most detailed and well-produced studio experiences in the world.
Klook Tip: The tour is self-guided and takes around 3–4 hours, so arrive early and give yourself plenty of time to explore.
3. Madame Tussauds London
Interactive wax hand-making experience at Madame Tussauds London
Madame Tussauds is one of those places that works for almost everyone, great with kids, perfectly enjoyable as adults, and consistently entertaining in ways that sneak up on you. The wax figures are impressive up close, and the themed zones (Marvel, movies and TV, sports, royals, and music) give the whole place a good flow.
It's one of the most popular fun attractions in London for families, but it doesn't feel overwhelming if you visit on a weekday. Beyond the wax figures, there are interactive experiences and rides inside, so it's not just a walk-through. Expect to spend a couple of hours here!
Klook Tip: Book your tickets online before visiting, it's cheaper and you'll skip the entrance line.
4. Thames River
A Thames Rockets speedboat races past the Old Royal Naval College in Greenwich, London
If you want something with a bit more energy on the Thames, a speedboat tour is one of the most fun things to do in London. The Ultimate London Speedboat Adventure blasts you along the river past Tower Bridge, the Shard, the Tate Modern, and the City, all narrated, often with a sense of humor.
It's different from the quieter pace of a standard river cruise, but it's exciting. The ride lasts around 50 minutes and covers a lot of the central riverside quickly. Try this if it’s your first time visiting London and want to see the city from the water without spending hours doing it.
Klook Tip: You’ll get wet, especially at the front. Wear layers and leave anything valuable in a bag.
5. Borough Market
Colorful drink displays and market stalls at Borough Market in London
Borough Market is one of the oldest and most-visited food markets in the United Kingdom, and it more than holds up to the reputation. Located just south of London Bridge, it's full of traders selling everything from fresh produce and aged cheese to hot food from around the world.
Klook Tip: Go on a Thursday or Friday when the full market is open and it's slightly less packed than Saturday.
It works well as a casual morning or lunchtime visit, but if you'd rather do a structured food tour of the area, a Borough Market food tour is a solid way to get the most out of it, you'll try more in two hours than you would explore alone. A great pick for anyone looking for fun things to do in London with real local flavor.
6. Phantom of the Opera show
Phantom of the Opera in His Majesty's Theatre
London’s West End is famous for its theatre shows, and Phantom of the Opera is one of its biggest classics. It's been running at His Majesty's Theatre since 1986, the longest-running musical in West End history, and the staging, chandelier drop included, is as theatrical as it gets.
Even if you've seen movie versions or know the story well, seeing it live in that theater is a different experience. The acoustics are excellent, the sets are extraordinary, and it moves fast enough that it doesn't drag. A great option to do on an evening, especially if you're traveling with someone who loves musical theater or someone you're trying to convert.
Klook Tip: Dress is smart casual at most West End theaters. Book seats in the dress circle for a great view of the full stage.
7. The O2
Visitors celebrate during the Up at The O2 rooftop climb experience in London
Climbing over the roof of the O2 Arena is one of those fun things to do in London that sounds a little crazy until you're doing it, then it just feels awesome. The Up at The O2 Experience takes you up a steep fabric walkway to a viewing platform at the top of the dome, 52 meters above the Thames, with views stretching across the river to Canary Wharf, Greenwich, and beyond.
It's more of an activity than a sightseeing stop; you're in a harness, walking in a group with a guide. The climb itself takes around 90 minutes round trip. It's a great choice if you want to feel a bit more active, and the views at the top are worth it.
Klook Tip: Sunset slots book up quickly, if the timing works, that's the one to go for.
