This is a £3 million treetop walkway that has been created in London, at the Royal Botanical Gardens in Kew. The Xstrata Treetop Walkway is 59ft (18m) in the air and was designed by the same people behind the London Eye (Marks Barfield Architects).

Some of the spectacular views that can be seen from the walkway include an old lady being mugged on Oxford Street, Chelsea fans crying in a cafe on King's Road and bankrupt stock investors throwing themselves from the top of One Canada Square.

If you look carefully in the bushes, you can spot young men and women indulging in the popular British pastime of "dogging".
