The London Underground (also known as the Tube or The Underground) is a fantastic way to get around London, it's easy and quick to use and stops near to all of the main London tourist attractions.
There are a total of 12 tube lines with trains running every few minutes between 05:30-03:30 Monday to Saturday, and 07:30-11:30 on Sundays. Free tube maps are available at any underground station office and you can access free tube maps online before you go, and you'll also find tube maps posted generously on station walls.
