The Colne Valley Regional Park is the first substantial taste of countryside to the west of London. The Park, founded in 1965, stretches from Rickmansworth in the north to Staines and the Thames in the south, and from Uxbridge and Heathrow in the east, to Slough and Chalfont St Peter in the west.

A mosaic of farmland, woodland & water with 200 km of rivers, canals and over 60 lakes

The Colne Valley Regional Park, formed in 1965 , stretches from Rickmansworth in the north, to Staines and the Thames in the south, Uxbridge and Heathrow in the east, to Slough and Chalfont in the west. Covering 43 square miles the landscape is a mix of bustling towns, green spaces and waterways which are the first taste of countryside immediately west of London.

The Colne Valley Park Trust aims to highlight this fantastic and varied area, its history, rich landscape and biodiversity. Many people live, work and visit the Colne Valley, but too few realise it forms part of a vibrant regional park.

Your Countryside in Crisis – a call for action!

The Colne Valley Regional Park is amongst the most pressurised parts of the Green Belt.  The Green Belt is seen by the market as a good development opportunity as there is a vacuum of policy addressing development pressures/‘needs’.

We have been advocating solutions over the last few years and are grateful to those in positions of power who have listened, understood and acted. But unfortunately our efforts to promote proper political understanding and buy-in are still not cutting through with key decision-makers. Therefore we have launched a campaign.

About the Regional Park

Students at Brunel University London and West London Film and Media CIC created this informative video.

It explores some of the many attractions in the Colne Valley Regional Park, highlighting the practical uses of the land, farming, angling, its many circular walks, and how to support it. The video also deals with the many threats and pressures facing the regional park due to its close proximity to the urban areas of west London, including giant infrastructure projects such as the High Speed 2 railway line.
