Starts at Nott Creek trail head, off Crawford Gulch Road. The longest trail in the park, Mountain Lion takes you through undulating hills, open meadow, aspen groves, and dense evergreen forests. At mile .6 a service road provides access to the Burro trail. At mile 1.3, follow a steep spur trail for half a mile to the old quarts quarry. Mountain Lion also passes through the Deer Creek backcountry camping area. Take a detour at the Windy Peak (mile 3.6) or City Lights Ridge (mile 5.4) spur trails for 360-degree views of the surrounding mountains. Buffalo trail intersects Mountain Lion at mile 4.7, providing access to the Forgotten Valley backcountry camping area. A challenging ride or hike, with great pay-offs.
