Any route or boulder problem that starts out of or near an occupied campsite may not be done without first obtaining the campsite occupant's permission.
The Wonder Bluffs is a less visited crag with a collection of variable quality cracks from 5.7-5.10b and some nice view of the surrounding area. Easterly-facing so plan on morning sun and afternoon shade.
Getting There
Start your approach from the vicinity of King Otto's Castle; there is some parking nearby. Cross the road and skirt Condor Rock on the right (west end) aiming for a boulder filled gully that leads to the base of the east-facing wall.
A little more effort is needed to reach this wall but the views from the base and lack of crowds make up for it. Plan on roughly 20-30 minutes for the approach.
