*Colne Valley Regional Park

'The Colne Valley Park covers 43 square miles of varied scenery ranging from semi-urban to unspoilt countryside. The area to the north of the M40 is a distinct valley with rolling chalk hills forming the valley sides. The wide valley bottom has a wetland landscape created by the River Colne, Grand Union Canal and a succession of lakes ... Ancient sunken lanes often link the settlements.

'Between the M40 and the M4, the valley becomes less pronounced as the chalk slopes become more gentle. This part of the Park has large woodland blocks and many historical parkland trees.

'The southern section of the Park consists of a flat plain created by the convergence of the flood plain of the River Colne and River Thames. This area is dominated by five large water reservoirs with steep grassland slopes.'
