An unusual view in the heart of the desert, Faux Falls, when flowing, is very impressive.
Faux Falls is located near the Ken's Lake campground off Route 191, 20 minutes south of Moab. When I was there it was during several days of thunderstorms. The waterfall was really gushing. Not sure how much water is running when there hasn't been rain in a while.
The falls can be seen from the campground. Follow a dirt road that leads right the base of the falls but you cannot drive this section. Just walk down the road. It is an easy walk. There is a trail on the right side of the falls. You can ascend over several shelves and fall the stream to a tunnel where the water exits the mountain. This is a man-made waterfall created when water was diverted from Mill Creek to form Kens Lake.
