Speedboat ‘THE THAMES BEAST’ from Tower Millennium Pier – 40 mins

The Thames Beast turns a sightseeing trip into a fast, splashy run along London’s working river. In 40 minutes, you pass the Tower of London, Tower Bridge, HMS Belfast, Canary Wharf, Greenwich, the Cutty Sark, the O2, and the Thames Barrier before racing back toward the Shard.

I like the small 12-person group, which keeps the ride more personal than a large river boat. I also like the easy Tower Millennium Pier meeting point and the choice of departure times. The tradeoff is simple: this is a high-speed overview, not a slow cruise with plenty of time to study every building.

Key points to know before you book

• A fast route with a lot packed in: The 40-minute ride reaches Greenwich and the Thames Barrier before returning upriver.
• Small maximum group: The RIB carries no more than 12 people, making it easier to hear the live commentary.
• Big London sights from the water: Expect views of Tower Bridge, HMS Belfast, Canary Wharf, the O2, the Cutty Sark, and the Shard.
• Straightforward starting point: Depart from Tower Millennium Pier on Lower Thames Street, near public transport.
• Weather and health rules matter: The trip requires suitable weather, and people who are pregnant or have heart, back, or other serious medical conditions cannot ride.
• Good fun, limited time: The speed is the main attraction, but it also means quick looks rather than long photo stops.

Why The Thames Beast is different from a normal river cruise

Most Thames sightseeing boats ask you to sit back and watch London slide past at a gentle pace. The Thames Beast takes the opposite approach. It is a RIB, or rigid inflatable boat, built for speed, and the river becomes part sightseeing route, part amusement ride.

That makes the experience especially appealing if you want to cover a large stretch of the Thames without giving up a good dose of excitement. You start beside the historic center, run east toward Greenwich and the Thames Barrier, then return with a view toward the Shard. The route gives you both old London and modern London in one compact trip.

The published price is $78.15 per person. That is not cheap for 40 minutes, so I would not choose this as your only Thames experience if your main goal is a detailed look at the riverfront. The value comes from the combination of speed, a small group, live commentary, and a route that reaches well beyond the central sights.

The strongest reason to pay the price is the feeling of movement. One moment you are near the Tower of London, and soon you are looking toward Canary Wharf, the O2, and Greenwich. You get a broad sense of how London changes along the river, from medieval stronghold to modern financial district to maritime Greenwich.

Meeting at Tower Millennium Pier

The departure point is Tower Millennium Pier, Lower Thames Street, London EC3N 4DT. It is an easy location to pair with a day around the Tower of London and Tower Bridge, and it is near public transportation.

Arrive at least 15 minutes before departure. This is important because missed departures are not refunded or rescheduled. You receive confirmation when booking, and the ticket is mobile, so you can keep it on your phone rather than arrange a paper voucher.

The activity ends back at the same pier. That makes planning easier. You do not have to arrange a pickup from Greenwich or work out a second route across London after the ride.

You should also expect some waiting or schedule changes if the minimum number of passengers is not reached. If that affects your departure, the operator will contact you 24 hours before and offer another time or date. The trip can also be canceled for poor weather, with a different date or a full refund offered.

Tower of London and Tower Bridge at the start

The ride begins with two of London’s best-known river sights. The Tower of London sits close to the pier, its heavy walls and towers giving you an immediate reminder that the Thames was once London’s main defensive and commercial route.

You will not have time to tour the Tower itself, and this is not a substitute for going inside. From the water, though, you get a useful sense of its position beside the river. The view is quick, so keep your camera ready before the boat pulls away.

Tower Bridge follows, and it is one of the strongest photo moments on the route. From the river, you see the bridge in the setting it was designed for, with its two towers framing the waterway. The boat’s speed adds energy, but it also means you may need to take several quick pictures rather than wait for a perfect composed shot.

If you want quiet architectural viewing, a slower sightseeing boat will suit you better. If you like seeing a famous structure while a RIB powers beneath or near it, this is an excellent opening stretch.

HMS Belfast and London’s changing riverfront

HMS Belfast is permanently moored on the Thames and provides a striking contrast with the Tower’s stone walls and Tower Bridge’s ornate towers. The historic warship is large, dark, and unmistakable from the water.

Again, the boat does not stop for a visit. Think of this part of the trip as a fast visual introduction. You can note the ship’s location and return later if you want to explore its decks and exhibits on foot.

As the boat heads east, central London begins to give way to newer development. This is where the route becomes useful for understanding the Thames as more than a line of postcard sights. You see a river that still connects old institutions, working docks, business districts, residential areas, and entertainment venues.

Live English commentary adds context as you go. Since the group is limited to 12 people, the guide’s voice should be easier to follow than it would be on a large open-deck boat. No guide names are provided, so you should book this for the route and format rather than for a particular presenter.

Canary Wharf and the modern city

Canary Wharf gives the ride a sharp change of mood. Glass towers replace the older masonry of the Tower area, and the riverfront feels wider and more open.

This is a good section for looking beyond individual buildings. From the water, the scale of the financial district becomes clearer than it often does from street level. The boat lets you connect the central riverfront with London’s eastern business center in a matter of minutes.

The speed is useful here because you are covering a long distance in a short outing. Still, do not expect much time to read signs or identify every tower. Listen to the commentary and take in the overall view rather than trying to document each building.

For first-time visitors, Canary Wharf helps show that London is not just old churches, royal buildings, and narrow streets. The Thames links several very different versions of the city, and this route makes that contrast easy to see.

Greenwich and the Cutty Sark

Greenwich is one of the key turning points in the experience. The area is closely tied to Britain’s maritime past, and the Cutty Sark, the famous sailing ship, is a clear marker of that connection.

Seeing the Cutty Sark from the river gives you a different angle from the usual approach through Greenwich. You will not go ashore, and there is no time to visit the ship during this 40-minute ride. If Greenwich is high on your list, plan a separate visit before or after the boat trip.

The Greenwich section also shows how quickly London’s character shifts along the Thames. The ride begins near royal and military landmarks, passes through a financial district, and reaches a place known for navigation, sailing, and world timekeeping.

Because the boat turns around after reaching the area around Greenwich and the Thames Barrier, this is a useful point to watch the river traffic and banks on both sides. You get a sense of distance that a central-only river cruise cannot provide.

The O2 and the Thames Barrier

The O2 is one of the route’s most modern sights. Its huge pale dome is easy to recognize from the water, and it gives the ride another strong change in character.

The Thames Barrier comes farther east and is one of the most practical pieces of infrastructure on the river. Its purpose is to help protect London from flooding, and its large silver-colored gates create a powerful sight from a fast boat.

This is also the point that explains why the route needs speed. Reaching the O2 and Thames Barrier from Tower Millennium Pier and returning in 40 minutes would not be possible on a slow cruise. The boat ride gives you a quick look at a part of London that many short central cruises never reach.

Do not book this expecting a full engineering explanation or a long stop at the barrier. The attraction is seeing the structure in its river setting, then turning back toward central London with the city spread out behind you.

The return run and the view of the Shard

The trip ends by heading back toward Tower Millennium Pier. The return gives you another chance to see the riverfront, this time with the Shard as a major visual marker.

The Shard is especially easy to recognize from the water because of its tall, tapering shape. The view helps place the central London sights in relation to one another, particularly as you approach the Tower area again.

You may find the return run more exciting than the outward journey because you now understand the route and can focus on the speed. It is also a good time to keep your phone protected and your hands free. High-speed movement and photography do not always work well together.

The boat returns to the original pier, so you finish where you started. That is convenient if you have dinner, a museum visit, or a Tower of London booking nearby.

What the small RIB format means for you

The maximum group size is 12 people. That is one of the best practical features of this experience. You are not lost among a large crowd, and the live commentary should be easier to hear.

A small RIB also feels more immediate than a standard sightseeing boat. You are closer to the river, more aware of the turns and acceleration, and more exposed to the weather. A complimentary plastic poncho is provided if conditions require it, but you should still dress for an outdoor ride.

The format is not ideal for everyone. Pregnant passengers cannot take part, and anyone with heart problems, back problems, or another serious medical condition is prohibited from riding. These rules are firm, not minor suggestions.

Children aged 13 and under must be accompanied by an adult. Children aged 14 and over may travel without an adult at a parent or guardian’s discretion, but every child must weigh at least 15 kilograms, or 2.36 stone.

Is $78.15 good value for 40 minutes?

At $78.15 per person, this is a premium short outing. You are paying for the RIB format, the small group, the speed, live commentary, lifejackets, and a route that reaches the Thames Barrier.

I think the price is easier to justify if you already have a full sightseeing plan and want one memorable activity rather than another standard museum or walking tour. The ride covers a lot of ground and gives you views that are hard to reproduce from the street.

The value is weaker if you want detailed sightseeing time. You will see the landmarks, but you will not tour the Tower of London, enter HMS Belfast, explore the Cutty Sark, or visit the O2. Those require separate tickets and more time.

The experience is recommended by 97 percent of customers and has a 4.8 rating from 35 reviews. The strongest praise centers on fun, family enjoyment, and the chance to see a large part of London from the river at breakneck speed. That matches the tour’s purpose well: it is an energetic sightseeing ride, not a quiet history lesson.

Who should book The Thames Beast?

I would choose this for couples, families with eligible children, and anyone who enjoys a little speed with their sightseeing. It is also a smart pick if you have already seen central London and want to reach Canary Wharf, Greenwich, the O2, and the Thames Barrier in one outing.

You should think twice if you dislike fast movement, need a slow pace for photography, or have a medical condition covered by the restrictions. A standard Thames cruise will be a better match for calm viewing and longer commentary.

Book only if the timing fits your day, since changes after booking may carry a £35 administration fee. Free cancellation is available up to 24 hours before departure, but cancellations or changes inside that window are not accepted and missed trips are not refunded.

Final verdict: book it for speed and range

The Thames Beast is worth booking when you want London sightseeing with real motion. The small group, clear meeting point, live commentary, and wide route make the experience easy to fit into a busy London schedule.

I would not use it as your only Thames visit. Pair it with time on foot at the Tower, Greenwich, or HMS Belfast, and the ride becomes a lively link between those places. If you want 40 minutes of fast views, river air, and a broad sweep from the Tower to the Thames Barrier, this is a strong choice. If you want slow observation, choose a conventional cruise instead.
