What's here?

Big Rock is located in southern part of Lake Perris State Recreation Area. While other small developed slabs surround Big Rock, most of the routes are found on the main wall, containing about thirty routes. Of these, less than 5 are cracks, with the balance being bolted face routes. The rock quality is very good, and with the routes facing northwest it gets lots of afternoon sun.

The routes are low-angled, with generally more than ample bolted protection. It is a great place for beginners and novices. Most all belays are three-bolt set-ups, many of which have been recently replaced. While most of the routes can be done in one pitch, some have bolted anchors midway, allowing one to practice belay switch-overs. There is some bouldering around the base of the rock, with more still on the surrounding hillsides.
A great historical link about Big Rock can be read here courtesy of Don Chambers,. Comments by some legends of the sport that many would not have guessed climbed at Big Rock.

Getting There

Access to Big Rock is via Hwy 215 exiting on the Ramona Expressway, heading east towards Lake Perris. About 7 miles down the road on the left is an unmarked park entrance road, called Bernasconi Rd. Left here leads to a self-pay station. Parking in the park is steep at $10.00 per vehicle, or one can park about 1/2 mile out of the park on Bernasconi and walk in for free. Once in the park, hike left through the picnic area on a paved service road for about 1/3 mile until Big Rock becomes apparent on the left hillside.
