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

Covers all of the ground level routes on the expansive Main Slab.

Getting There

Park in the fee parking area ($10/day) and hike west along a paved service road to reach the obvious west-facing Big Rock.

Plan on a 10-15 minute approach from the parking area.
Break ins are not uncommon, so keep valuables out of sight!
