The open area north of Cap Rock is home to the Planet X Area which contains a number of quality routes as well as the popular Planet X bouldering.
Notable areas here include the sunny The Love Nest which is home to a handful of quality sport routes in the 5.11 range, the free-standing Planet X Pinnacle which has a great 5.8 crack/face route as well as some other face routes in the 5.9-5.11+ range and The Crypt, a more recently developed area with routes in the 5.7-5.11 range.
Getting There
Look for a dirt pullout about 1.4 miles from Hidden Valley Campground and 0.3 miles before Cap Rock that's on the left (east) side of the road if coming from Hidden Vally CG.
A well-defined and marked trail leads across the desert to The Love Nest which is visible from the car and on the approach. Hiking east a bit further will get you to Planet X Pinnacle as well as the Planet X Bouldering area. The Crypt lies a bit further east still, although it can also approached from the vicinity of the Hall of Horrors.
Approach times vary from 5-20 minutes depending upon the area.
