Single and double track, loop, variable terrain, cliff conditions so you need to dismount in one spot. Fast changing weather. Occasional joggers + horses. Average Ride under 2 hours. Is a great ride in either direction.
In Boulder, use Flagstaff Rd. @ Chatauqua park go about 6 or 7 miles. Has A small dirt road on left (south) side to reach trailhead. Watch for cyclists climbing Flagstaff Rd. <br /><br /><br />From Golden, go north on Hwy 93 to Coal Creek Canyon dr. (Hwy 72) take a left and go approx 8mi to Gross Dam rd on the right, road may not be marked but it is ~.5mi past the Boulder County sign. Take a very sharp right onto this dirt rd (nearly 180deg) and go 2.7mi to the Crescent Meadow parking lot on the right, just past the railroad tracks.
