Thames River Cruise London to Greenwich: What to Expect

Thames river cruises are one of the more popular things to do in London—but they’re not all the same, even though they tend to get lumped together like they are. Some stay in central London and hit the main sights, others run out to Greenwich, and some go all the way to Hampton Court.

We took the Thames River cruise from central London to Greenwich—the longer route that gets you out of the tourist core. It's a narrated tour, so there's lots to learn about the city.

👉🏼 Short on time? The London to Greenwich Thames River cruise gets you on the river without turning it into half your day. You can check prices here.

What you see on a Thames River cruise (London to Greenwich route)

The most famous landmarks are near the beginning and end of the cruise, while the middle is a quieter stretch of river. That makes it more of a scenic ride than a nonstop landmark parade.

Tower Bridge

Tower Bridge comes up as soon as the cruise begins.

We’d already crossed it the day before on a hop-on hop-off bus, so we weren’t expecting it to feel much different. Wrong—it looks a lot better when you’re under it instead of stuck in traffic on top of it.

Once you’re underneath it, you realize just how big it actually is—those people overhead look tiny against the base of the towers.

The bridge is named for the nearby Tower of London, which the guide points out as you cruise by. This is where Anne Boleyn was held before Henry VIII had her executed—one of several wives who didn’t have a long run

Look for the gate in the wall facing the river—all royal prisoners came in this way, straight off the Thames—and that was the point. No way out.

Continuing along this stretch of the river, you start to notice the mix of architecture—older buildings with columns and domes alongside newer glass-heavy structures.

You get a clear view of the London Eye from the water, where you’re close enough to see how it’s put together, instead of just this big circle on the skyline.

HMS Belfast

One of the first sights is the HMS Belfast, a battleship launched in 1938 that served in World War II and the Korean War. it’s now permanently docked as a naval museum, and you can go onboard and walk through the ship if you want a closer look.

You can't miss it from the river. It just sits there, heavy and out of place compared to everything around it—a holdover from when Britain still ran much of the world.

The sun never set on the British Empire because God didn’t trust the Brits in the dark.

Docklands

Next the cruise passes through the Docklands area, which used to be the center of London’s shipping for hundreds of years. This is where goods were loaded and unloaded when the river was still the city’s lifeline.

At low tide, you start to see what that actually looks like—river stairs, worn edges, bits of infrastructure that only show when the water drops. It’s not all glass buildings and redevelopment.

That said, you’ll also pass places like the ExCeL convention center and a stretch of hotels and restaurants built for conference crowds, so it’s a mix of old and new.

It’s not the prettiest stretch, but it’s where you start to see the more functional, everyday side of London.

Financial District

After that, the skyline shifts and London’s modern skyline takes over—glass towers, sharp lines—nothing like the older parts of the route.

On a gray day like ours, the clouds sat low enough that it looked like the buildings were pulling them down around them.

It even looked like there was a tornado forming over one of the buildings—just to complete the whole gray, miserable London weather experience.

Greenwich

The cruise ends about five miles downriver at Greenwich Pier—and it’s Gren-itch, not Green-witch. Worth knowing so you don’t embarrass yourself in front of the locals.

Greenwich is where Greenwich Mean Time—GMT—comes from. And yes, there is an actual line that divides the eastern and western hemispheres—it’s not just in Bugs Bunny cartoons.

You can walk up into Greenwich Park to the Royal Observatory, where the Prime Meridian runs. It’s a bit of a climb, but that’s the price of getting your “stood in two hemispheres” photo. Just know they charge admission if you want the official “standing on the line” spot inside the Observatory grounds.

If you don’t feel like hiking up the hill, the Cutty Sark is right there when you get off the boat. It’s a paid museum, not something you just wander onto.

A lot of people get off here—but you don’t have to. We stayed on because London Eye was calling—and we had tickets.

The return trip may be the same stretch of river, but it doesn’t feel like a repeat. You notice different things on the way back.

Is the Thames River Cruise to Greenwich Worth It?

If you’re expecting nonstop major sights the whole way, this isn’t it. The first stretch is strong, the middle gets quieter, and then it picks up again toward Greenwich.

If you want an easy way to see a wide stretch of London without walking all over the city, it works. You get a mix of landmarks, skyline, and parts of London most people never see.

You also don’t have to treat Greenwich like a required stop. A lot of people get off and turn it into part of their day. We didn’t. We stayed on and rode it back, and it still felt worth doing.

That’s really the key difference with this route—it works either way. You can turn it into a half-day stop or just use it as a round-trip cruise and be done.

If you’re tight on time, that flexibility matters more than anything else.

Bottom line: a cruise on the Thames River may not be the most exciting thing you’ll do in London, but it does exactly what it’s supposed to do.
