Lee Valley Regional Park offers hundreds of great days out, it has award winning open spaces and sports venues along the 26 mile long, 10,000 acre park. The park was created by a unique Act of Parliament as a “green lung” for London, Essex and Hertfordshire. Their approach is to be community focused and commercially driven, to work with partners to produce a unique combination of activities, sights and experiences for everyone to enjoy.

Lee Valley Leisure Trust came into operation on 1 April 2015 to run 14 of the major sports venues and other sites owned by Lee Valley Regional Park Authority. The Trust is part of the Authority's aspiration to establish Lee Valley Regional Park as a world class visitor destination and commitment to utilise public funds as efficiently and effectively as possible.
