Access Issue: Rebolting Complete! Details

CA State Parks officially reopened Big Rock to public access April 28th, 2018. After months of effort 53 anchors and 232 bolts have been upgraded to 1/2" X 2.75" stainless steel Powers 5-piece bolts and rings.

Description

This is the creatively named 200 foot high, west-facing granite slab which is the focal point of the area. Almost all of the routes here are easy to moderate slabs with the odd crack thrown in for variety.

Despite the easier ratings the climbs here tend to have an "old school" feel to them and may seem run-out to those unaccustomed to such routes - caveat emptor.

Getting There

Park in the fee parking area and hike in along a paved service road to reach the obvious west-facing "big rock". Plan on a 10-15 minute approach from the parking area.
