Vauxhall
From Free Running Wiki
Vauxhall is a hotspot in London, known for it's crazy maze of walls which have difficult routes through to easy routes (making it popular with Urban Freeflow). It also has a lot of catleaps and such.
It is quite a walk from the other popular spots on South Bank, making it not as popular as it should be, however The Oval is nearby for the cricket fans among us.
