The area acts as a crucial flood management zone for the Colne Valley river system. Landscapes vary between wetlands, grasslands, and woodland patches, supporting a high concentration of local wildlife. The park features a dense web of public footpaths, including sections of the Colne Valley Trail. It is physically defined by the confluence of the River Colne and the Grand Union Canal.
