Many street cars will be able to reach the lower trailhead off E. Fork Road. There are some rocky arroyo crossings beyond about 37.402, -106.82 that will stop low clearance cars and RVs. Look for parking or camping spots and ride on up the road to the trailhead.
Treasure Mountain is a hidden gem east of Pagosa Springs. From the lower trailhead, the trail climbs on moderate grades through scenic aspens and firs. Eventually, the trail intersects Windy Pass Trail
If you plan to do this trail as a shuttle, from the top of Wolf Creek
Pass, heed the warning above. You'll ride the CDT to the top of the ski area and look for a rock carin and a USFS sign posted on a tree. These will be your only clues that there's a trail here because there's literally not signs of an actual path. Make your way down the grassy gully and head right when you reach the flat meadow below. Use of the MTB Project mobile app
will be crucial to keeping you on track here. Head left into the trees and down the second pitch. Thr trail becomes much more apparent here, but it's still faint by most standards.
When you reach Wolf Creek
Road USFS #725, head left for about a mile with a little climb to the epic singletrack downhill section of the trail. Drop down the steep sidehill through the burn area.
After some great views and narrow sidehill, you'll come to another steep moonscape section. After a few creek crossings and real mountain downhill riding, you'll arrive to a big, open meadow that is the Windy Pass Trail
intersection. The rest of the trail has more flow and speed as it sweeps through aspen groves and meadows. Once you arrive at a cattle gate, the ride shreds down a sidehill through oakbrush and open slopes until you reach the bottom.
The ride can be done as an out-and-back from the East Fork with many hike-a-bike sections after the Windy Pass Trail
It's better done as a shuttle from the CDT at the top of Wolf Creek
Pass or riding up Wolf Creek
Road USFS #725 to avoid the top steep section. Most people leave a car at the large parking area at the start of the East Fork Road #667.
