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.

Made of sandstone, the slopey vertical and slab climbs that made up the summit rock are nearly all enjoyable. Some of the rock will crumble, and this isn't an area that should be climbed after a recent rain storm.

Nearly all routes are sport, though there are also few trad routes available.

Summit Rock does see some sun in the afternoon, though the lower belay areas are often in the shade.

Getting There

From the main Castle rock gate: Travel north in your car on Skyline Boulevard about a half mile. After passing the Los Altos gun club on the left (the have a large banner-like sign) you will see a large driveway on the right approximately a 1/4 mile later. There is a parking area 100 yards in.

From Skyline Boulevard and Big Basin: Travel south 1.5 miles until you see a large driveway on the left side. Pull in, and park 100 yards later. If you pass the Los Altos gun club on the right, you've gone too far.

From the Summit Rock parking lot: Approach time: 10 - 15 minutes. Follow the trail out of the end of the parking lot which will wind it's way gently uphill. 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.

Summit Rock is technically inside Sanborn-Skyline County Park. Doesn't change anything, really, but it might explain all the broken glass. Jul 12, 2002

Someone please add "Farewell to Arms". That is a fun route! I would add it but I can't remember any details. Jun 16, 2004

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. May 24, 2011

Hey All - Matt here from the Bay Area Climbers Coalition. We have been working with the land manager that oversees this crag to do stewardship events and trail work at this crag.

The land managers have asked that we stay off the climbs that go through the nest of the peregrine falcons - we have put tags on the anchors and the first bolts of the climbs.

Thanks for being awesome and respecting the natural habitat of these birds - the nest seems to move every year so we will move the tags each season to accommodate. Oct 28, 2015
According to…: The seasonal closure of Summit Rock is Feb 1 - Aug 31, 2017. May 8, 2017
