The Denton Reservoir
Edit: Park at Bridge 65 (there is no public right of way along the track to the reservoir ‘point A’). Take your time when negotiating the rough track leading from the road to the bridge.
Good news is, there is now a permissive path from Bridge 65 directly to the reservoir – avoiding walking on the short road section near the letter ‘A’ on the map. Entrance to the permissive path is unmarked, but otherwise well trodden and easy to follow. Look for the gap in the hedge as you begin to climb the track over the bridge.
