I took the circle trail counter-clockwise. Starts with the Phippen Recon Trail, to the North 40 Trail to the Lost Wall Trail, the Rock Wall Trail, Ranch Road Shortcut and then finish on the Phippen Recon Trail again. Elevation gain is minimal - only 200 feet but the view you get from the highest part of the trail are pretty good. The trail is well marked with maps that show "YOU ARE HERE".
I give this hike 4 boots!
