This trail was designed for hiking and mountain bicycling. To avoid user conflict, it is closed to horseback riding and motorized vehicles. Stay on the trail and avoid the temptation to make your own shortcuts. The black rubber bars set across the trail are water bars, designed to carry runoff away from the trail and prevent erosion. They are safe to ride over on a mountain bike. It is recommended that you begin the Indian Springs loop on the south side of the road, by the register. This will greatly reduce possible conflict with other users and will eliminate a climb between Spillman and Indian Springs. All roads to the trailhead are suitable for passenger vehicles.
