Things to Do in London: Outdoor Adventures

While it's true that London boasts more museums, historic sights and galleries than you can visit in a lifetime, it's also a city where you can ride the waves like an Olympian at Lee Valley White Water Centre and swing through the trees like Tarzan at Go Ape! London's parks are famous – it has the greatest area of city centre greenery – but you can also swim at 6am at Hyde Park's pool or take the plunge in the natural ponds at Hampstead Heath.
