A big city like London offers different ways of transportation to visit the attractions and monuments: on foot, by public transportation, by car, by bike...
We strongly recommend you to purchase a Visitor Oyster Card
, the best way to have access to public transportation in London. These cards can be bought and reloaded once you arrive at the city. Then, you can start using the bus, the underground, etc. You can also move comfortably by bike or on foot along London, without having to use a different option.
