The Colne Valley Regional Park was established in 1965 and is the first large area of countryside to the west of London.

The landscape of the north of the Colne Valley Park is dominated by a pronounced valley with many attractive viewpoints over the string of flooded gravel workings that now form attractive lakes from Rickmansworth Aquadrome to Uxbridge that are used by wildlife, anglers and water sports clubs .  The Grand Union Canal, the Colne, Colne Brook and Frays running through the valley are joined by the Chess,  Pinn, Misbourne and Alderbourne  as well as many smaller streams.

The proposals for High Speed 2 will have a huge impact on this attractive landscape with a 18m high x 3km long viaduct, the Chilterns and Northholt tunnel entrances, many construction sites and materials stockpiles.
