Overview/ApproachThe Grotto is narrow canyon tucked away several hundred feet above the sandy floors of Diablo Canyon. To get to The Grotto, continue past Winter Wall along floor of the canyon. On the right hand side of the was there will be a cluster of Pinon trees with a visibly worn path. Go left here and continue up the talus slope, there are multiple paths up this area so feel free to find your own way. Occasionally there will be cairns marking the trail up to the canyon, but I am yet to be able to find them all the way up.The Grotto has 35+ routes ranging from 5.8 to 5.12d
East Wall - as you climb into the Grotto from the floor of Diablo Canyon, this will be the wall on the left.

A 200' rope, quickdraws, and a helmet is all that is needeed for sport climbing in The Grotto. The hike up the slopes into The Grotto from the wash of Diablo Canyon doesnt require anything more then sneakers, but I would advise against sandals.
