About Williamson Rock:


The US Forest Service has closed Williamson to all climbing due to a ruling by the US Fish and Wildlife Service that the area is critical habitat for the Yellow Legged Mountain Frog, an endangered species. The Friends of Williamson Rock has incorporated as a non-profit organization under IRS Code Section 501(c) to regain climbing access to Williamson. The organization needs your help. To find out more, go to our website:

Williamson Rock offers over 300 routes in the mountains above Los Angeles with no dirt roads to drive and minimal hiking to access. Mostly sport climbing, this area is hugely popular which means this area gets crowded on the weekends, although typically the further uphill one hikes the fewer the crowds and sense of serenity. The majority of routes are well-protected and thought-out with convenient anchors and clipping stances and are played out on steep, featured granite. Located at an elevation of 6700' the season runs from March through October depending upon weather and road conditions. No facilities exist at the crag so pack your trash out and walk away from the stream and routes to bury your waste.

Nearest town or city: Wrightwood
Directions: Located along Highway 2 between Kratka Ridge Ski Area and Windy Gap Campground just west of some tunnels. Drive time is about 45 minutes from La Canada in the west and 30 minutes from Wrightwood in the east. Parking is available in either the main parking area (with signs) or another 200 yards to the east. The approach from the main parking lot will take about 15 minutes while the longer and more scenic approach from the other lot can take up to 40 minutes. Hiking times may be longer returning to your vehicle as it's mostly uphill on the way back.
