I've never run into another climbing party there in 6 trips to this falls over 5 years.
At the South end of Canandaigua Lake @ the Hi Tor Wildlife area. Parking area south of Parish Hill Rd on 245. Approach time to the top 15-20 minutes. 30 minutes if you walk up the creek to the base (be on the lookout for the falls on the right about 1/2 mile up the creek - it's easy to walk past)
In the same gully (Conklin Gully) there is another great climb in the main amphitheater. As far as I know it doesn't have another name. These are both very close together and a short (but steep) walk from the trailhead.
