Hartman Camp is located along the Sespe River Trail about 9.5 miles downstream from Piedra Blanca Trailhead. This site has long been in use, first as a USFS Guard Station in the 1920s and later as a car campground in the 60s and 70s. Now what remains is a pleasant stand of mature live oaks in a large grassy flat on the bank above Sespe Creek.
