London is a city defined by its river, and while there are many bridges and tunnels, few crossings are as stylish—or as swift—as the RB4 River Bus. Operated by Uber Boat by Thames Clippers, this dedicated ferry service bridges the gap between the historic charm of Rotherhithe and the gleaming towers of Canary Wharf.
But this isn’t just any boat ride. As of late 2025, the RB4 route has become a pioneer in green travel, hosting the UK’s first fully electric cross-river passenger ferry. Whether you are a cyclist looking for a shortcut, a commuter dodging the tube crush, or a visitor wanting a unique view of the capital, the RB4 offers a travel experience that is as efficient as it is scenic.
What Makes This Route Special
The RB4 is unique in the Transport for London (TfL) river network. Unlike the longer commuter routes that meander from Putney to Greenwich, the RB4 is a dedicated “shuttle” service. It does one thing, and it does it brilliantly: it gets you from the south bank to the north bank in under four minutes.
The real headline, however, is the vessel itself. If you are lucky enough to catch the newly launched Orbit Clipper, you are riding on the future of London transport. This fully electric boat is whisper-quiet, meaning you can hear the lapping of the Thames against the hull rather than the roar of a diesel engine. It’s a zero-emission journey that feels thoroughly modern.
For cyclists, this route is a game-changer. The new vessels are designed with a “roll-on, roll-off” capability and can hold up to 100 bicycles. No more awkwardly lifting your bike over ledges; you simply glide on and glide off, making it the most cycle-friendly river crossing in London.
A Route Breakdown: Old Docklands To New Heights
The journey may be short, but the contrast between the two stops is striking. It’s a tale of two Londons, separated by just a few hundred metres of water.
Rotherhithe (DoubleTree Docklands)
Your journey begins (or ends) at the Rotherhithe Pier, situated right next to the DoubleTree by Hilton London Docklands Riverside. This area feels like a village within the city. It is steeped in maritime history, with converted warehouses and cobbled streets nearby. The pier here has been recently upgraded to be fully accessible, ensuring everyone can enjoy the river.
Before you board, take a moment to enjoy the peace of Rotherhithe. It is a fantastic spot for a quiet riverside walk along the Thames Path, offering uninterrupted views of the city skyline without the crowds.
The Crossing
The journey itself is a quick burst of excitement. As the boat pulls away, you get a panoramic view of the river bend. To your west, the City of London’s skyline peeks through; to your east, the river winds towards Greenwich. The electric propulsion of the new vessels makes for an incredibly smooth ride, allowing you to snap a stable photo of the skyscrapers looming ahead.
Canary Wharf Pier
In less time than it takes to listen to your favourite song, you arrive at Canary Wharf. Stepping off the boat, you are immediately immersed in the energy of London’s financial district. The pier drops you right into the action, minutes away from world-class shopping, diverse dining options, and the immaculate Jubilee Park.
Service Frequency And Connections
One of the best things about the RB4 is its reliability. You don’t need to study a timetable intensely because the boats are remarkably frequent.
- Weekdays: Service typically runs every 10 minutes during peak times and throughout the day.
- Weekends: Expect a service every 15 minutes.
The service runs from early morning (around 6:30 am on weekdays) until late at night, making it perfect for both the morning commute and a post-dinner return trip.
Connections are excellent on both sides:
- At Canary Wharf: You are a short walk from the Elizabeth Line, Jubilee Line, and the DLR, opening up the rest of London.
- At Rotherhithe: You can connect to the C10 bus route or enjoy a scenic walk to the Rotherhithe Overground station.
Tickets And Value For Money
Travel on the RB4 is seamlessly integrated with London’s transport system, though it has its own fare structure. You can use your Oyster card or contactless payment card to touch in and out at the pier readers—just like on the Tube.
While the fare is higher than a standard bus ride (expect to pay around £5.90 for a single adult journey using contactless), you are paying for speed and convenience. It saves you a lengthy detour via the Tower Bridge or the Greenwich Foot Tunnel.
Top Tip: If you are staying at the DoubleTree by Hilton Docklands, ask at the reception! Guests often get complimentary usage of the ferry, which is a fantastic perk.
Top Tips For The Journey
- Go Electric: Try to spot if you are boarding the Orbit Clipper. The silence of the electric motor is a unique experience on the busy Thames.
- The Night View: Travel after dark. Canary Wharf is dazzling when lit up at night, and seeing the reflections in the water from the open back deck of the ferry is magical.
- Bring Your Bike: If you are exploring London on two wheels, this is your best friend. It bridges the gap between the cycling paths of South East London and the cycle superhighways north of the river.
- Wrap Up: If you choose to stand on the outdoor deck (which you definitely should for the views), it can get breezy on the river, even in summer.
Planning A Day Out On This Route
The RB4 is the perfect connector for a “Best of Both Worlds” day out.
Start your morning in Rotherhithe. Visit the Brunel Museum to learn about the tunnel that changed the world, or take a wander through the Russia Dock Woodland for some greenery. It is quiet, atmospheric, and historically rich.
When you are ready for a change of pace, hop on the RB4. In minutes, you’ll be in Canary Wharf for lunch. The area has transformed from a sterile business district into a leisure destination. You can visit the Crossrail Place Roof Garden (which is free!), grab a bite at one of the many waterside restaurants, or even try your hand at fairground games in one of the new entertainment bars.
Year-Round Appeal
The river is beautiful in all seasons. On a crisp winter morning, the mist over the water is atmospheric and moody. In the height of summer, the breeze off the Thames provides a welcome break from the urban heat. With the comfortable indoor cabins of the Uber Boat fleet, you are protected from the elements, ensuring the RB4 is a viable option rain or shine.
Whether you are a local cutting your commute time in half or a tourist looking for a unique vantage point, the RB4 ferry offers a quick, clean, and cool way to cross the capital’s iconic river.
