1.7 miles from Potrero John Trailhead to Potrero John Camp in the Sespe Wilderness
Trailhead located on HWY-33 at Potrero John Creek
Elevation: Trailhead 3696 Camp 4152
The trail leaves HWY-33 plunging instantly into the spectacular gorge cut through the rugged and rocky pine studded terrain by Potrero John Creek. On the other side of the gorge, it opens up into a fairly wide open wash-type expanse created by the torrential runoff that drains into Potrero John Creek from the Pine Mountain watershed, which is formed by Reyes Peak (7514) to the west and Haddock Mountain (7361) to the east. Potrero John Camp is set beside the creek beneath these mountains.
The camp makes an excellent staging ground for further exploration of Potrero John Creek. Up the canyon 1.2 miles from camp is Potrero John Falls. Several other smaller falls are located along the feeder streams that drain into the creek from Reyes Peak.
Potrero John Creek watershed can be extremely dangerous during rainy weather due to flash flooding and mud and rock slides: Rescued Hikers on Potrero John January 18, 2010
