With 791 acres of ponds, woodlands and grasslands, Hampstead Heath is one of the largest urban parks in the world. Here you can swim, fish, hike, fly a kite, or simply enjoy unspoiled nature and wildlife. Open-air concerts are a regular feature on the grounds of Kenwood House, located on the northern part of the Heath. Don’t miss the marvellous view of London from the top of Parliament Hill.
