Blackhawk Pass, also known as Segment 26 of the Colorado Trail, is a beautiful section of trail running through the rugged San Juan Mountains. This trail is a highly rated 10.9 mile black diamond singletrack trail beginning at Forest Road 578 (Hermosa Park Road) and ending at Forest Road 550 (Hotel Draw Road).
This trail is open to Mountain Bikers, Hikers, Backpackers and Bikepackers, and can be enjoyed in both directions.
Mountain Bike Route: Most mountain bikers when seeking an epic high country ride will park at the Upper Hermosa Creek parking lot and ride up the road to Bolam Pass. Continue 10 miles on Bolam Pass, past the Greysil Mine, until you reach Celebration Lake. Head west and you will find the singletrack. After descending from Blackhawk Pass, the trail drops onto Hotel Draw Road. Many turn right (heading uphill for 0.5 miles) and turn left onto West Cross Creek Trail, also known as Stagecoach, which will bring you back to the Upper Hermosa Creek parking lot.
Leave early and expect storms. Be Colorado prepared!
