Walk at the Moor Green Lake Nature Reserve, the end of a series of lakes now reclaimed following 50 years of gravel extraction. The reserve is a great place to walk with easy-going accessible paths and several circular routes of various lengths. For the more adventurous, you have the option of exploring the Three Castles Path which runs as far as to Windsor in one direction and Winchester in the other, or the Blackwater Valley path which will take you on a scenic lake-filled route down the valley to Aldershot.
