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: williamsonrock.org
This information is a public crowdsourcing effort between the Access Fund,
and Mountain Project. You should confirm closures, restrictions, and/or related dates.
This, the last crag developed at Williamson Rock, is guarded by one of the longest approaches at Williamson Rock, the other being Straits of Magellan, making this is a crag to seek out if you want to get far from the maddening crowd.
Those who make the long hike to this crag will be rewarded with long routes in a beautiful wilderness setting far removed from the din and confusion of the lower areas.
The best routes here include Kiton (5.10c), Valkyrie (5.11b) and All Guns Blazing (5.11b).
Approach as for the The Pyramid, passing along it's east face and then slog uphill along the southern aspect of the Pyramid aiming for the top of the ridge where the Summit Block will be visible off to the left. Once at the top, turn around and enjoy the view before heading down and right for several hundred meters where the crag will come into view. The approach takes 15 minutes or so from the Pyramid and about 45-60 minutes from the closest parking area.
