Access Issue: Falcon Nesting Closure at Castle Rock
Details
Castle Rock in Pine Canyon and the Wanna Get Away areas are closed for peregrine falcon nesting season, from February 1 through July 31st every year. All other Mount Diablo area crags are open to climbing. The news release is linked here parks.ca.gov/NewsRelease/493.
Description
Along with Toast to the left, Gruntle is another well-protected 5.10. It's a decent warm up, and is suitable for newer leaders who are ready for the grade.
Clamber up appealing step-like features, clipping two bolts slightly to the left of the most natural climbing line. Then start high-stepping, mantling, and generally gruntling your way to the anchors. The crux is up high and feels similar to the start of Amazing Face.
