Williamson Rock is currently closed to climbing. MORE INFO >>>


Williamson Rock was Southern California's premier sport climbing area until its closure in December 2005. The area features nearly 300 quality routes of all grades from beginner to expert level on highly featured granite. Located in the Angeles National Forest in the San Gabriel Mountains, an hours drive from the city of La Canada, north of Los Angeles, on Highway 2, or 1/2 hour from Wrightwood, if driving from the east.

Prior to its closure in December 2005, in order to protect the dwindling population of the Mountain Yellow Legged Frog (MYLF), Williamson Rock was Southern California's most popular sport crag, and there is a new USFS proposal to reopen the crag in August 2016, from August 1st through November 15, under a Visitor Use Permit system. Williamson Rock is a summer climbing destination, offering quality routes from 5.6 - 5.13, in a beautiful mountain setting, located at 7,000 feet elevation.

The climbing at Williamson Rock can be characterized by technical, often strenuous movements requiring good core strength, body english, creative technique, and endurance to succeed. One should be a competent leader, as there are few opportunities to setup top-ropes without leading. As evidenced by the occasional old rusted bolt and hanger, climbing took place at Williamson Rock in the 1960s, but the development of modern sport climbing began in 1987, and Williamson Rock realized its true potential in the mid-90s with route development by Troy Mayr, Sam Owings, Kevin Mokracek, Jack Marshall, and others. For most routes 8 - 12 quickdraws is sufficient to enjoy the often steep, exciting, and exposed climbing at Williamson Rock.

Getting There 

Follow the climber's trail from the Williamson Rock parking lot, located about 1/4 mi. east of the Eagles Roost picnic area on SR 2 (Angeles Crest Highway). The approach takes about 15 minutes.

Originally bolted in 1990 an extension with a second seperate set of anchors was added in 2002. Long, sustained and powerful this route requires good core strength and the ability to pull down hard with good technique. Starting on a short slabby ramp to steep overhanging terrain on good flakes, crimpers and jugs to a short rest at the first set of anchors. Continue on for three more bolts on scary flakes to the second anchor....[more]   Browse More Classics in CA

Went out there a few days ago. Just went off a guide book and didn't know about the closure. Only one small sign near trailhead mentioned it being closed. We called the forest department and spoke with them. When asked when it might reopen they told us no time soon.

2 more years. I would like to hope the climbing community can band together to put up a legitimate fight this time around.

I wonder if the luminaries who closed this area understood that other crags hereabouts (SoCal) would be adversely impacted? Scientists tend to wear blinkers.

Holcomb Valley Pinnacles comes to mind.
