Boulder Ranger District
Mountain Biking
General Information
The Boulder Ranger District offers many opportunities for mountain biking, ranging from short, flat and easy to long, steep and technical. Many of the trails and all four-wheel drive roads on our district are "multi-use" in purpose. However, it is important to remember that not all hiking trails are open to mountain bikes. When in doubt, refer to the trail information signs posted at the trailhead and remember that bikes are prohibited in the Indian Peaks Wilderness and James Peak Wilderness.
When biking on trails in the national forest, please do your part to protect our natural resources. Do not go around, damage, or remove water-bars and other man-made structures. These structures are crucial to the protection of trails from erosion, plus they prevent excessive mud and wash-out conditions. Going around water-bars or damaging them makes them ineffective, causes severe resource damage and will ultimately lead to permanent trail closure.
