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 trail crosses the road and continues gently climbing along the ridge above Horse Ranch for a further 1.5 miles and from there it is 2 miles downhill to the Horse Ranch Road.
To return to the start you can either retrace your steps (7.5 miles) or follow the paved Brush Creek Trail (2.5 miles) along the east side of Brush Creek Road back up to the start
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.
Directions from Snowmass Village Mall: Follow Brush Creek Road 0.4 miles to Divide Road; turn left onto Divide Road and immediatly right onto Deerfield Drive. You will see the signed Rim Trail sign going uphill on your left. The middle of the trail can be accessed by taking Brush Creek Road then Sinclair Road to the trail crossing point.The northern end of the trail can be accessed further down Brush Creek Road to Horse Ranch Drive opposite the golf course.
