It is a huffer puffer trail! Trail surface is mainly rocky with short sections of hard packed earth. Hiking sticks and plenty of water is recommended. Some go up Old Baldy and then go back down on the Super Trail, making a loop. The track for this route is in and back on Old Baldy.
There is a memorial on the saddle for Boy Scouts that got caught in a freak snow storm on the mountain. Trailhead
