Walking is a popular recreational activity in London, despite traffic congestion. There are many streets that provide interesting walks, especially within historic central London, In addition there are attractive commons, parks, canals, and disused railway tracks that provide space for walks. This includes Wimbledon Common, Epping Forest, Hampstead Heath, and the eight Royal Parks: Hyde Park, Regent's Park, Richmond Park, etc. In recent years access to canals and rivers, including the Regent's Canal, and the River Thames has been greatly improved, and as well a number of long-distance walking routes have been created that link green spaces.

Ramblers is the trading name of the Ramblers Association Great Britain's walking charity. The Ramblers is also a membership organisation with around 100,000 members and a network of volunteers who maintain and protect the path network. The organisation was founded in 1935 and campaigns to keep the British countryside open to all.
