Honestly, Greenwich tends to get bumped down the to-do list when exploring London.
Not because it isn’t worth it, but because it sits just far enough outside the usual circuit to feel like a project rather than a plan.
UNESCO-listed, completely walkable, and with a food and drink scene that’s quietly got very good, it earns a full day out in a way that most London neighbourhoods simply don’t. Here’s what to actually do when you get there.
1. Stand on the Prime Meridian at the Royal Observatory
It’s one of those things that sounds slightly naff until you’re actually standing there with one foot in the eastern hemisphere and one in the western, and you realise it’s genuinely one of the more surreal moments London has to offer.
The Royal Observatory was built in 1675 by Christopher Wren, sits at the top of Greenwich Park with views over the Thames and the city, and houses a planetarium, historical navigational tools, and one of the UK’s largest telescopes.
The Astronomy Photographer of the Year exhibition runs until August 2026 and is worth the visit alone. Allow at least an hour, more if you get pulled into the galleries, which most people do.
2. Explore the Old Royal Naval College
One of the most architecturally spectacular buildings in London that most people walk past without going inside.
The Old Royal Naval College is a UNESCO World Heritage Site, designed by Christopher Wren (he had a busy few decades), and its Painted Hall has been compared to the Sistine Chapel. It’s genuinely not an exaggeration.
Entry to the grounds is free, and the Painted Hall has a small admission charge. The baroque interiors are extraordinary, and the building itself makes for some of the most dramatic photography in the whole of southeast London.
3. Visit the Cutty Sark
The last surviving tea clipper in the world, dry-docked right in the heart of Greenwich since 1954.
The Cutty Sark is one of those landmarks that looks impressive from the outside and reveals something genuinely fascinating once you’re inside—there’s a café in the dry dock underneath the hull that gives you a real sense of the scale of the ship.
Worth the ticket price, particularly if you’re visiting with people who like their history served with a bit of drama.
4. Wander Greenwich Market
Dating back to 1737, Greenwich Market is the only market in London located within a UNESCO World Heritage Site, which gives it a rather good backstory before you’ve even had a look at what’s on offer.
Arts and crafts, antiques, London designer-makers, and a food court with enough variety to keep any group happy.
It’s open Thursday to Sunday, and the covered Victorian arcade makes it a solid option regardless of weather. One of the better markets in London if you prefer browsing to buying.

5. Walk up to the top of Greenwich Park
Free, and one of the best views in the city.
Greenwich Park is one of London’s largest Royal Parks, and the hilltop near the Royal Observatory gives you a panoramic view across the Thames, the Isle of Dogs, Canary Wharf, and the city beyond that most Londoners would pay good money for.
The walk up from the town centre takes around 10 to 15 minutes and is worth every step. In summer it fills up with picnickers; in autumn it’s all golden leaves and dog walkers. Both versions are excellent.
6. Take a Thames Clipper into Greenwich
The DLR works perfectly well, but arriving into Greenwich by river is categorically the better experience.
The Thames Clipper runs from central London directly to Greenwich Pier, and the journey itself is half the point—passing under bridges, watching the city open out into something wider and older, arriving at a neighbourhood that still feels like a proper village despite being very much part of London.
Worth doing at least one leg of the journey by boat if you can.
7. Go Up at The O2
One of London’s better-kept secrets, considering how many people walk past the O2 without realising you can climb it.
The Up at The O2 rooftop walkway takes you up and over the dome of what is consistently rated the world’s most popular entertainment venue, with views across the Thames, Greenwich, Canary Wharf, and beyond.
It’s weather dependent, and you’ll need to book ahead, but it’s one of those experiences that delivers significantly more than you expect.
8. Explore the National Maritime Museum
Free entry to the permanent collection, which covers everything from Britain’s naval history to Admiral Nelson’s coat (the one he was wearing at Trafalgar—with the bullet hole, which is exactly as sobering as it sounds).
The museum caters well for all ages, with the AHOY! Children’s Gallery at one end and serious maritime scholarship at the other.
The building itself, set in what was once the Royal Hospital School, is worth seeing. Allow a couple of hours.

9. Take a ride on the Emirates Air Line
Technically it’s a cable car rather than a ride, but it’s one of the more underused and genuinely fun things to do in the area.
The Emirates Air Line runs between Greenwich Peninsula and the Royal Docks, offers aerial views of the Thames, the O2, and the Thames Barrier, and takes about 10 minutes each way.
It runs on the Oyster card system, so you can fold it into a day out without any additional faff. Good for kids, good for photos, and good as a slightly unexpected way to get from A to B.
10. Have lunch at the Trafalgar Tavern
A proper Thames-side pub with one of the better riverside settings in London, sitting right on the waterfront next to the Old Royal Naval College.
The Trafalgar Tavern has been here since 1837, has served Dickens and Gladstone, among others, and still does traditional British food alongside a good selection of ales.
Worth booking a table if you want to sit by the window with a view of the river. The kind of pub that makes Greenwich feel properly, unhurriedly special.
11. Visit the Queen’s House
An often-overlooked gem sitting between the National Maritime Museum and Greenwich Park.
The Queen’s House was the first classical building in England, designed by Inigo Jones in the 17th century, and houses a substantial art collection, including works by Hogarth and Gainsborough.
Entry is free, it’s rarely crowded, and the Great Hall is quietly breathtaking. The spiral Tulip Staircase was the first geometric self-supporting spiral staircase built in Britain, and it photographs beautifully.
12. Catch the Greenwich and Docklands International Festival
Running annually across outdoor spaces in Greenwich, this is one of London’s most ambitious free arts festivals and one of the most underattended given the quality of what it puts on.
Large-scale outdoor performances, aerial shows, and site-specific theatre across the borough, with most performances free to attend.
It typically runs late August into early September, making it a strong reason to time a Greenwich visit around that window if you can.
