The large eastern face of Castle Rock covers the area from the edge of the North Wall to the edge of the South Face. It has a mix of sport, trad, and mixed, bolt and gear routes. Shade in the afternoon. Less crowded than the west side of Castle Rock.
Getting There
The fastest approach is to take the south road/trail from the trailhead, and head north on the trail that goes along the east front of the rock. Look for a flagged sign for Crimson Arete and follow the trail uphill to the left. The majority of the routes are in the "notch" on the east face and are reached by the Crimson Arete trail.
