Marshall Mesa - Doudy Draw Loops Mountain Biking Trail

The Doudy Draw Loops are configured like a two-leaf clover at the base of the iconic Boulder Flatirons. From the trailhead, a simple gravel trail climbs to a junction between Spring Brook Loop North and Flatirons Vista South.

We like to start on Spring Brook Loop North. It steadily climbs to a level section of trail with breathtaking views of the Flatirons and Eldorado Canyon. The second half of the loop is a fast and fun downhill back to the trail junction.

There is a steep and unexpected hill climb to the start of Flatirons Vista South, so be ready to power through the short but rocky climb. Once on top of the Flatirons Vista Trail, the riding is easy with panoramic views of Boulder and the Front Range. Cruise around the loop and then bomb down the steep hill you previously climbed, for an enjoyable and flowy ride all the way back to the trailhead.
