Located in the northern foothills of the Angeles National Forest, Big John Flat, also labeled as Ball Flat on some maps, is an out-and-back road across the transition from hills to the Mojave Desert basin, providing beautiful desert scenery.
The trail is easy, with only a single location that is rutted, requiring straddling the rut, but it remains an easy trail for new offroaders.
Dispersed camping is allowed when following the Angeles National Forest Dispersed Camping Restrictions. There are a few small campsites suitable for 1 or 2 vehicles and a large staging area size camping location near the end of the trail.
Open fires are prohibited in this area.
