Piru Creek Bouldering

To access the Piru Creek boulders, you must get onto the I-5 freeway. If heading north on the five from the LA area, you'll get off the first exit north of Castaic at Templin Highway. Turn left and drive under the freeway, then turn right onto the California Golden State Highway which basically runs parallel with the freeway. It's an asphalt road the entire time, but the road has quite a few potholes. After turning onto the Golden State Highway drive for about 5-10 minutes until you reach a big gate and can't drive any farther. There is parking all along the sides of the road. The parking is for "Frenchman's Flat," a campground which Piru Creek runs through. If interested in the sandstone blocks, pull over on the side of the road about 200 meters before you reach the parking lot. In the gully are two radical boulders, with some great problems. The conglomerate boulders are found downstream in the canyon. Follow the trail which runs parallel on the southern side of the creek. It's about a 1 mile hike in, which will take about 10-20 minutes, and you know you're pretty much there when the trail forces you to do a short class four scamper down 15 feet or so of rock.
