Hi Sue, The waterfall can be found if you walk the foot path between Blakeley Reservoir and Wesseden Reservoir with Wessenden Reservoir further up the footpath, The spot where it can be seen quite clearly is very near Wessenden lodge. it can be reached by taking the A635 Greenfield road,over Saddleworth moor then taking the Wessenden head road for 150 yards or so parking in a lay-by on the right close to the footpath,or near Marsden on the Wessenden road parking at the side of Butterley Reservoir.
