Buy an Oyster card to save on transportation in London

Purchase an electronic Oyster card at a Tube station for £5, charge it with a cash value, and use it on the Tube or on buses around the city. You reload it with money as needed. Another option is a Travelcard, sold for a specific number of days (even one day) of travel and good for buses and for specific zones in the Tube system. Buses are a good way to see the town, particularly if you plan to hop on and off to cover many sights—but don’t take a bus if you are in a hurry. See more travel tips in our London Travel Guide.
