The area closes when muddy, and the trailhead has a parking lot with 25 spaces and one ADA space with a fee required. Bicycles, including Class 1 and Class 2 e-bikes, are allowed on designated trails, so be aware while running. Dogs must be leashed seasonally to protect ground-nesting birds, and horses are permitted on most trails too.

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.

Really an old dirt road, this trail makes a great connector between the other trails in the area of Marshall Lake. Watch out for fast-moving mountain bikers!

These great plains are representative of the large natural areas surrounding Boulder. Within the Open Space and Mountain Parks, these areas are protected from the excesses of intensive agriculture. They are home to many wild species, both plant and animal, some of which are endangered.
