Description Suggest change

The Naked Boulder has a nice selection of easy to moderate climbs. The northwest face is a big slab, the southeast is vert, and the northeast face is slightly overhanging problems.

This boulder doesn't appear in "Bay Area Rock".

Getting There Suggest change

As you walk northwest from Nature N**i area along the Skyline trail for a few hundred feet, this will be the largest boulder you see to your left. There's also a Skyline Trail connection to the road just across from the Castle Rock main entrance which is perhaps the easiest approach.
