South of Telluride, the Wasatch Horse Trail is a scenic 17 mile loop (4,550) combines dirt roads past the Bridal Veil Falls, the Wasatch Trail and a descent by the Bear Creek Canyon waterfalls. Don t underestimate this loop -- it could be the most difficult route in the US.
From town, ride east on Colorado Avenue for 2 miles up to Pandora Mill. As the road turns to dirt, climb another 2 miles (1200) to the top of Bridal Veil Falls. At the fork, stay right through the gate past the old power plant. Up ahead, look for a side trip to Silver Lake. Continue up to the junction with Blue Lake Road and again veer right (unless you want to check out Blue Lake). Through the course of ascending the next several miles, generally stay right at intersections climbing to a high of 13,000. Eventually, descend an extremely narrow, rocky singletrack into Bear Creek Canyon. Follow the dirt road back into town.
Overall, Wasatch Horse Trail is the 21st most popular horse trail of all 67 horseback rides in Colorado.
