Covering 1,000 acres (400 ha) on either side of the River Lee Navigation between Waltham Abbey and Broxbourne, it is an area of lakes, watercourses, open spaces and three Sites of Special Scientific Interest (SSSI) linked by footpaths and cycle tracks.
The site straddles the Hertfordshire/Essex boundary.
