Description
This circuit is comprised of 50+ problems located near the backside of Cyclops Rock (Manx Boulders) as well as a bit further east (Asteroid Belt) and commonly approached from the vicinity of Hidden Valley Campground.
Problems in this circuit range from V-easy to V11 with all but a handful in the V5 and under range.
Notable problems here include The Boxer Problem (V2), Out of Touch (V2), Undertow (V3), Optigrip (V3), Off Camber (V4), Peabrain (V4) and Pigpen (V4).
Getting There
Park in the large day use lot beneath the east face of Intersection Rock or along the road across from Cyclops Rock and the entrance to Hidden Valley Campground.
A good trail exists that circles around the front of the huge Cyclops Rock and leads directly to the Manx Boulders; the trail to the Asteroid Belt takes off from the Manx Boulders and follows an obvious sandy wash.
- It's about a 5-10 minute walk to the Manx Boulders and another 10-15 minutes to the Asteroid Belt.
