Two established traverses on pretty good quality sandstone, both about fifty feet in length. One is in the sun most of the day and the other is in a cave and may get some sun in the morning. Both have top outs. The traverse inside of the cave seems to have chiseled holds :(
Go up Santa Maria Rd from Topanga Cyn Blvd. Access the trailhead via the first dirt turnout on the right. Walk to the second intersection on the trail, turn right. The first traverse is on the steep side of the most prominent sandstone slab, the second is just below that in a cave. Approach time: about five minutes.
