Description Suggest change

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

Getting There Suggest change

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 frequent, so keep valuables out of sight.
