Located in the Cucamonga Wilderness, and managed by the Angeles and San Bernardino National Forest. The less traveled Chapman trail take off from the more traveled Icehouse Canyon Trail, a mile up from the Icehouse Canyon trailhead. On Chapman trail, Ceder Glen Campground another 1.5 miles. The camp sit in a wonderful small bowl with Incense-Cedars, Jeffrey pines and Douglas-firs, it is a dry camp when I was there. Parking for the trail heads can fill up on weekends before sunrise.
