There are actually 15-25 rock routes ascending the face of this cliff. Difficulty ratings range from 5.4 to 5.14R. First completed by Gerry Brindel, Larry Koehler, Buzz Jenks, William Miller, and several others. If you seek further info on the face climbs, feel free to contact me.
Took the ski trail up King Mountain, don't see a reason to go back as I was disappointed by the view to effort ratio. Robertson Lake Cliffs as I've explored them numerous times, for good reason.
