An in-depth guide to London’s sightseeing bus routes. Discover the difference between the Red, Blue, and Green lines and plan your perfect itinerary.


Navigating London is easier when you understand the color-coded Hop-On Hop-Off bus network. Each line serves a different purpose—from ticking off the big bucket-list icons to exploring deeper into royal parks and museums.
Here is your detailed guide to the paths, stops, and monuments along each route.
Most major operators (Big Bus, Tootbus, City Sightseeing) follow a similar logic, though route names might vary slightly.
This is the route you see on postcards. It hugs the River Thames and circles the absolute center of London. If you only have one day, this is the line to ride.
Tip: The section along the Thames Embankment offers uninterrupted views of the skyline. Sit on the left side of the upper deck when traveling towards the Tower for the best river views.
Head West! This route is leafier, grander, and perfect for a more relaxed pace. It often overlaps with the Red Route at key hubs (like Victoria or Marble Arch) allowing you to switch easily.
These shorter routes are designed to shuttle people from major transport hubs into the main sightseeing loops. They are functional but still pass interesting spots.
To maximize your ticket, you'll want to switch routes ("hop") at these major hubs where lines intersect:
| Hub | Connections | Nearby |
|---|---|---|
| Victoria Station | Red ↔ Blue | Buckingham Palace, Theatres |
| Marble Arch | Red ↔ Blue | Oxford Street, Hyde Park |
| Green Park | Red ↔ Blue | The Ritz, Luxury Mayfair |
| Trafalgar Square | Red ↔ Green | National Gallery, Soho |
Pro Strategy: Start your day on the Red Route to see the big sights before crowds peak. Around lunchtime, switch to the Blue Route as crowds thin out in the west, and spend your afternoon in a museum or Hyde Park.
