Mid Colne Valley, Protected valley and natural reserve in Harefield and Denham, United Kingdom
The Mid Colne Valley extends over 132 hectares, featuring four lakes bordered by the River Colne and the Grand Union Canal.
The lakes within the valley originated from sand and gravel extraction operations conducted between 1960 and 1980, transforming the landscape.
The Broadwater Lake Nature Reserve serves as a center for ecological research and bird observation, managed by the Hertfordshire and Middlesex Wildlife Trust.
Visitors can access the valley from Moorhall Road near the Colne River bridge, with walking paths along the Grand Union Canal towpath.
The site contains Coppermill Down, one of Greater London's last remaining unimproved chalk grasslands, where pyramidal and bee orchids grow naturally.
