The Spring Brook Loop is a great introduction to mountain biking in Colorado’s Front Range, offering a mix of technical challenges and awesome views. The trail features a series of rocky step-ups, rolling singletrack, and winding paths through forests. The ride is mostly sun-exposed, so pacing water is important, and the trail is shared and popular with hikers, runners, and other bikers. Highlights include the descent through Doudy Draw and the twisty, wooded sections of the Spring Brook Loop. The trail loops back, offering expansive views of the Flatirons before returning to the starting point.
