San Lorenzo Canyon is jointly managed by the U.S. Fish and Wildlife Service and the Bureau of Land Management as a primitive recreation area. This scenic east-west canyon offers ample outdoor opportunities for hiking and primitive camping. Not only a destination for hikers, the Canyon offers outstanding opportunities for photographers. Millions of years of Earth’s history unfold in San Lorenzo Canyon, a picturesque area of sandstone cliffs, arches, and hoodoos. The cottonwoods indicate there may have been a reliable water source at one time in the area. The area has remnants of old ranches and homesteads; springs and tiny creeks are hidden in the canyon bottoms and washes. High clearance and/or 4-wheel drive vehicles are recommended. There are no restrooms or drinking water.
Rather hard to find the road onto the correct road to get to the right road! Once headed to the west look for the sign taking you to the right into a dry wash. Follow the arroyo past a giant "bread loaf" that is a geological unconformity. Drive into an abrupt canyon with straight walls and side slots. Eventually you run into a rock wall that can be traversed by scrambling around it and continue 1/2 mile to a short pour-off. Camping is allowed but be aware of flash floods. It's a narrow canyon with only one way out. A parallel road just to the south of San Lorenzo Canyon is all on BLM land (dispersed camping). Pack it in, pack it out.
