There are thousands of things to see and do in London, and the fastest way to explore all of them is by metro or as it is known by Londoners "the Tube" - the first and the largest underground railway in the world (maybe on a par with Moscow metro only). Just avoid rush hours: 07.00-09.00 and 17.00-19.00. As famous as the Tube are London's red buses, especially nr. 11 as it traveling via some most famous landmarks (length is about 7 miles).
