Rated Intermediate due to the length of trail which is approx 13miles. You can add the Mayhem Gulch climb up to Centennial which adds approx 4 miles. This is some nice, flowy singletrack which takes you high up on the ridges above Clear Creek and offers incredible views. The singletrack is smooth, the switchbacks are rideable. The climbs are relatively easy. We like to do this trail clockwise so that you get the doubletrack done first and the rest of the ride is total singletrack. Watch out for the blind switchbacks however!
Directions: From West U.S. Hwy. 6 and State Hwy. 93 west of Golden, travel west on Hwy. 6 about 11 miles. Turn right at Hwy. 119, and travel about 1/2 mile. Turn right onto Douglas Mountain Road and travel about one mile to Centennial Cone Road. Turn right and travel and go about a mile to Centennial Cone Rd., the west entry to the park. http://mapq.st/y0vPuo
OR, about a mile before you get to Hwy 119, you will see a parking lot on the right. This is Mayhem Gulch trailhead. Park here and to a nice climb up to Centennial Cone (which gives you a wonderful downhill back to your vehicle at ride’s end!)
