London’s Big Bus Tour company runs 3 different routes around and through the city, offering single or multi day tours, and optional attraction packages. The bus also runs some night tours.
The open-topped, double-decker buses take in almost all the sights and attractions London has to offer with a “Hop-on/Hop-off” system so you can visit any or all of them as often as you like and stay at each place as long as you like!
With over 50 well placed stops and buses arriving every 10-15 minutes, it couldn’t be easier to see all of London and enjoy the recorded commentary in 12 different languages.
Check out their video for a sample of one of the tours.
