If you're riding the Camp Tamarancho Loop, this is where the riding starts to become more difficult. The first 3/4 of a mile along this trail is a consistent climb - not too challenging or steep, but steady. Then, the trail adds in some big features, including one known quite simply as "the rock," a big rideable boulder (with an optional bypass) that adds a nice challenge for more experienced riders.
The last 1/4 mile includes a bunch of climbing switchbacks, and the trail eventually ends at another obvious dirt road. Cross this road, and you'll be on Wagon Wheel Trail.
