London hop-on hop-off bus tour: routes, stops and tickets explained

What is a London hop-on hop-off bus tour?

A London hop-on hop-off bus tour is a sightseeing service that runs a fixed loop past the city’s main landmarks in an open-top double-decker bus. One ticket lets you board at any stop, ride as far as you like, get off to explore, and rejoin the next bus that arrives at the same stop. Big Bus London is the official operator of the route covered in this guide and runs services across central London every day of the year except 25 December.

Buses depart at high frequency — typically every 15 to 20 minutes during the day — so you almost never wait long. Recorded multilingual commentary plays on board so you understand what you are looking at as the bus moves. You can plug in your own headphones at the seat to follow along in your language.

The Big Bus London route at a glance

The Big Bus London route loops through central London and stops at most of the postcards you came for: Westminster, Big Ben and the Houses of Parliament, Buckingham Palace, Trafalgar Square, Piccadilly Circus, Marble Arch, the Tower of London and Tower Bridge, St Paul’s Cathedral and the South Bank. A full loop without hopping off takes about two hours, but most visitors stretch the day out by hopping off four or five times.

Where to start

You can board at any stop. If you want a memorable upper-deck photo on day one, most visitors start near Trafalgar Square, Marble Arch or Victoria. Your ticket activates the first time you scan it on board, so it does not matter where you join.

How it compares to other ways of seeing London

Compared to walking, the bus covers far more ground per hour and lets older travellers, families with small children and travellers with mobility limitations keep up with the city. Compared to the Underground, you actually see London above ground while you move between stops.
