Boreas Pass and Gold Dust Loop

The terrain is quite varied. The Boreas Pass Road section is primarily a well-maintained dirt and gravel road with a gradual incline. As you ascend, it can become rougher with embedded rocks. The Gold Dust Trail, however, is predominantly singletrack, featuring sections with roots, large rock boulders, log bridges, and flume trails. Expect both smooth, flowy parts and more technical areas, including rocky descents and challenging rock gardens.

The overall loop is rated as difficult due to its length, elevation gain, and the technical sections of the Gold Dust Trail. While the Boreas Pass Road portion is generally considered beginner-friendly with a gradual climb, the Gold Dust Trail singletrack is rated intermediate to hard, with steep climbs and technical descents. Beginners might find the full loop challenging, especially at altitude.

The route offers stunning views of the Colorado Rockies, including the Tenmile Range, Quandary Peak, and the Blue River Valley. You'll pass through aspen groves and pine forests. Historical elements are also prominent, with vestiges of the mining era such as an historic water tank, a roundhouse, the renovated Section House (now a backcountry hut), and a railroad boxcar at the Boreas Pass Summit.

You can typically access the loop from either Breckenridge or Como. In Breckenridge, parking is often available near the start of the Boreas Pass Road. If starting from Como, there are usually parking options within the town or near trailheads.

The best time to ride is typically from late spring through early fall, generally June to September. During this period, the snow has usually melted, and the weather is most favorable. Fall offers spectacular views with vibrant aspen foliage. Always check current trail conditions and weather forecasts before heading out, as high-altitude sections can retain snow longer.

Yes, the loop is generally dog-friendly. However, dogs must be kept on a leash at all times to protect wildlife and ensure the safety of other trail users. Please remember to pack out all pet waste.

No, there are typically no specific permits or fees required for mountain biking the Boreas Pass and Gold Dust Loop itself. However, as parts of the route are within the Camp Hale-Continental Divide National Monument, it's always good practice to be aware of any specific regulations or closures that might apply to the monument area.

While there are no specific permits required for mountain biking this loop within the monument, riders should always adhere to Leave No Trace principles. Stay on designated trails, respect wildlife, and be aware of any seasonal closures or specific rules posted by the U.S. Forest Service that manage the monument lands.

Yes, the route also passes through sections of the Great Divide Mountain Bike Route, the Gold Dust Trail, and the Baker's Tank Trail. You may also encounter smaller segments of the Black Powder Pass Trail and Forest Road 50.

For a slightly easier experience, consider riding the loop in a clockwise direction. This allows for a more gradual climb up Boreas Pass Road and a more technical descent on the Gold Dust Trail, which some riders prefer. Also, starting early in the morning can help you avoid afternoon thunderstorms, which are common in the Colorado mountains.

Given the length and altitude, it's essential to be prepared. Bring plenty of water, high-energy snacks, a bike repair kit (including a spare tube and pump), sun protection (sunscreen, hat, sunglasses), layers of clothing for changing weather, and a first-aid kit. A GPS device or a downloaded map is also highly recommended, as cell service can be spotty.
