Kimball Canyon Crag Rock Climbing

Kimball Canyon Crag is a 100'ft tall steep-sided plug of Volcanic Rhyolite with multiple fine quality sport routes of varying difficulty, length, and architecture. There is no route here rated less than 5.10 so it is not really an area for moderates. A great resource is Jim Thornburg's Bay Area Rock guidebook which features a section on Kimball Canyon Crag and the routes here (starting on pg.66)

There are routes in the shade and sun depending on season and the time of day. Many of the North facing routes are in the shade most or all of the day which is very desirable on the hottest days of the year. The hike in might be blazing, but you know before you arrive that the shaded exposure of the North Face will be up to 20 degrees cooler. You can generally climb here any month of the year, though occasionally it can be cold and windy.  

Many of the routes can be top-roped by ascending the access trail to the summit which continues past the North Facing routes for 100 feet before terminating at the base of a 3rd class scramble. Once there scramble up past a small tree and pass through a 15 ft' tall natural archway. From there once sorted, locate the accessible anchors above each climb. An obvious landmark on the top is the easily accessible anchor of Black Sheep Squadron 5.10d about midway across the North facing cliff
