Battersea Park is one of the nicest parks in London. There is so much to see and do whether on foot, bike or skates. History is plentiful and all around the park. The Cache location is a fine example of the history - take the time to have a read through the history and background when you get here. (www.batterseapark.org).
Please exercise stealth in the area as there are lots of Muggles.
