Summit Rock contains some really beautiful views of the San Jose area from the tops of the climbs. It's too bad that the bottoms of the climbs and often the interemediate ledges are filled with trash and broken glass from picnicers and partyers above. So, beware sticking your hands places you haven't seen if you're climbing a route for the first time, especially if it looks like the route hasn't been climbed in a while.

At the fork, take the left fork (read the sign if you're not sure) and follow it uphill to the rock. From the top of the rock, follow the fence around to the right and downhill. Work your way around the rock following the dirt path.
Skill Saw Gourmet is a lot tougher than it looks. The move to the first bolt is challenging but is easier than what follows. After you clip it you have a myriad of flared hands and suspect feet at your disposal. Move right past the second bolt and work the arete up past the next couple bolts. Its like a good boulder problem followed by some more pumpy stuff.Finally you reach an easy slab which you basically walk up until the steeper part right at the top. For this it is wise to place a cam ...[more]Browse More Classics in CA
The Access Fund is currently trying to negotiate with Santa Clara County Parks to have a seasonal closure of Summit Rock. This would allow Peregrine falcon nesting and fledging from January through July and leave Summit available for climbing the rest of the year.
Santa Clara county parks is issuing permits to climb at Summit Rock , but only during 'non-nesting' season , which is October 1 through January 1st... So no climbing at Summit Jan 1st through September 31...
