Parks and open spaces

A 2013 report by the City of London Corporation said that London is the "greenest city" in Europe with 35,000 acres (14,164 hectares) of public parks, woodlands and gardens. The largest parks in the central area of London are three of the eight Royal Parks, namely Hyde Park and its neighbour Kensington Gardens in the west, and Regent's Park to the north. Hyde Park in particular is popular for sports and sometimes hosts open-air concerts. Regent's Park contains London Zoo, the world's oldest scientific zoo, and is near Madame Tussauds wax museum. Primrose Hill is a popular spot from which to view the city skyline.

Close to Hyde Park are smaller Royal Parks, Green Park and St. James's Park. A number of large parks lie outside the city centre, including Hampstead Heath and the remaining Royal Parks of Greenwich Park to the southeast, and Bushy Park and Richmond Park (the largest) to the southwest. Hampton Court Park is also a royal park, but, because it contains a palace, it is administered by the Historic Royal Palaces, unlike the eight Royal Parks.

Close to Richmond Park is Kew Gardens, which has the world's largest collection of living plants. In 2003, the gardens were put on the UNESCO list of World Heritage Sites. There are also parks administered by London's borough Councils, including Victoria Park in the East End and Battersea Park in the centre. Some more informal, semi-natural open spaces also exist, including Hampstead Heath and Epping Forest, both controlled by the City of London Corporation. Hampstead Heath incorporates Kenwood House, a former stately home and a popular location in the summer months when classical musical concerts are held by the lake. Epping Forest is a popular venue for various outdoor activities, including mountain biking, walking, horse riding, golf, angling, and orienteering. Three of the UK's most-visited theme parks, Thorpe Park near Staines-upon-Thames, Chessington World of Adventures in Chessington and Legoland Windsor, are located within 20 miles (32 km) of London.
