Corner Mountain is a very simple ride and can connect to numerous other trails in the area. The USFS parking at the trailhead is well marked on Wyoming SH 130 about 1.5 miles west of the Centennial Visitor Center.
Head up the little hill by the potty shack and choose either direction at the first fork. This route shows counter-clockwise, but it is actually an easier ride when done clockwise due to one technical rocky section that is tough to clean going up, but fun to go down...
To extend the ride, connect to the Camp Loops.
