A photo of the south side of the area. Kind of far...
This climbing area is situated on the cliffs that are right on the beach at the end of the Tennessee Valley trail. The only climbing I have seen there has been bouldering on the lower ends of the cliffs and overhangs, but for anyone looking to do some roped climbing you could give it a shot. Living in the area and having worked specifically on that beach for 4 months with the NPS, I can say that it may be sunny everywhere else in the county, but chances are its going to be 15 degrees colder on the beach and likely some fog. The rock can be slippery on wetter days so bring some chalk and a towel. You don't even need a bouldering pad because you are cushioned by the sand or water. Usually this beach has a small amount of people on it.
Best to go when tide is low or around neutral. Requires a small hike of about 1.5 miles.
From San Francisco take 101 south. Take the Stinson beach exit before heading onto the Richardson Bay overpass. There should be some sea planes on your right. Take a left on Marin Ave. and continue until you take a left onto Tennessee Valley road. Follow the road for about 1.5 miles until you come to the parking lot. From there it is a 1.5 mile hike to the beach. Look for the cliffs on both the north and south sides of the beach.
