The London Travelcard is a paper ticket that is valid on all London public transport.
Online exclusive: you can not buy a paper 7 Day Travelcard from Underground stations in London — it can only be bought in advance.
Unlimited travel: the Travelcard gives you unlimited travel on London’s public transport
network.
No queuing: while other visitors wait in line at the train station with their heavy bags, you’ll be ready to travel as soon as you arrive in London.
Low prices: a Travelcard is of great value, and you get a discount on the Tames Riverboats and Emirates Air Line cable car.
Should I buy an Anytime Travelcard or an Off Peak Travelcard?
