(S/E) The start is the small car park above Cow Green Reservoir (grid ref. NY810309) where you immediately get a feeling of the wild country forming this part of the North Pennines. From the car park walk back up the road and take the first path on the right (grid ref. NY812307) heading roughly south east. Reaching a cross track, turn left and continue to a tarmac track.
(1) Turn right and follow this access road to the dam to join the Pennine Way. Do not cross the bridge but bear left onto the Pennine Way heading south to Middleton-in-Teesdale.
(2) The waterfall is a short distance downstream below the bridge. If you wish to visit Falcon Flints, then continue along the Pennine Way as far you wish. The return route follows the outward path.
