This a good trail for a challenging snowshoe in the winter and hiking and biking in the summer with fine views across Snowmass Village, the ski areas and surrounding mountains. The easiest direction to travel this trail is from south to north as described here.
From Deerfield Drive the trail climbs steeply for just over a mile to the ridge via a number of switch backs. It then follows the fence line keeping generally along the ridge with great views off each side and a number of steep ups and downs along the way. There are two choices down to the midpoint at Sinclair Road the easier contouring down round the side of the hill the harder following a steep narrow ridge down. It is 3 miles from the start to this point.
The section north of the Sinclair Road is closed from 9/15 to 6/21 as the trail crosses a wildlife sensitive area. From Sinclair Road to return to the start you can retrace your steps if you enjoyed the ridge (3 miles) or alternatively walk down Sinclair Road to Brush Creek Road and turn right to join the paved Brush Creek trail (2.5 miles) which will take you back up to the mall through Snowmass Village.
