This staircase, obviously now in a state of disrepair, use to allow visitors to Hamilton Pool, near Dripping Springs, Texas, to walk all the way around the pool under the overhanging rock formations. My memory of it is that it has always been a little shaky and was always slippery from being constantly soaked by the falling water.
