there is a10ftwide by an 8ft tall boulder, you can work on at the top of the falls. there is a lot more climbing right next to the fall but the ground isn't flat so placing a crash pad is hard, and since it's near the water there is a lot of bugs and the holds get wet a lot of the time. the wall can get to 40ft ish, but I don't think top roping is allowed in the south mountain reservation, so that's annoying. I would say there is 50ft of climbable space if you can get your pad to lay flat, and don't mind it getting a little wet.

its a little hard to get to, no trail goes right to it, so its best to find a map. if following the yellow trail go to where it says maple fall, then go off trail along the little stone creek downhill and should lead you to it. if on the trail downhill from where it says maple falls, follow the stone creek uphill you find it.
