Williamson Rock is currently closed to climbing. MORE INFO >>>
Williamson Rock is under a temporary closure to all recreational uses, including climbing, pursuant to a ruling by the U.S. Fish and Wildlife Service that the area is critical habitat for the endangered yellow-legged mountain frog. Efforts by the non-profit organization Friends of Williamson Rock, in conjunction with the U.S. Forest Service, are underway to regain climbing access to Williamson. For information on the status of these efforts, and to learn how you can help, contact the Friends of Williamson Rock: http://williamsonrock.org
One of the best and most popular routes at Williamson. Starting on the right-most bolts on the Stream Wall the route heads up to a small roof and then right stepping over a cleft in between the two walls, cross over to the London Wall, following the line of bolts right to the arete. Protect the traverse to the arete w/ a long runner. The route finishes straight up the arete on open slopers and the occasional good crimp.
