This route was planned by komoot.
This route is considered difficult and requires very good fitness. It involves significant elevation gain, with grades of 7% or more in some sections, especially on the climb to Coal Bank Pass. While primarily paved, be prepared for some unpaved or difficult segments.
The best time to cycle this route is typically from late spring through early fall, once the high mountain passes are clear of snow and before winter conditions set in. Always check local weather conditions, especially for high-alpine environments, as they can change rapidly.
Generally, no specific permits or entrance fees are required for day-use cycling on the paved roads like the Million Dollar Highway within the San Juan National Forest. However, always check the official USDA Forest Service website for any specific regulations or alerts, especially if you plan to venture onto designated trails or camp.
Starting from Hermosa, you would typically find parking within or near the town. Specific trailhead parking for this touring route would depend on your exact starting point within Hermosa. Consider public parking areas in Hermosa or Durango, which is a short distance away, and plan your ride accordingly.
While dogs are generally allowed in the San Juan National Forest, this specific touring bicycle route is primarily on paved roads (US 550, the Million Dollar Highway). Cycling with dogs on busy highways can be unsafe for both the dog and the cyclist. If you plan to bring a dog, ensure they are securely leashed and consider alternative, less trafficked routes or trails where it is safer and more appropriate for them.
The scenery along this route is consistently described as unsurpassed, often referred to as the "American Alps." You can expect spectacular vistas of rugged peaks and stunning landscapes, with breathtaking views at every turn. The route is part of the famous Million Dollar Highway, renowned for its natural beauty. While Coal Bank Pass itself might be surrounded by trees, the overall ride offers magnificent mountain panoramas.
Yes, while primarily a road cycling route, it does pass near or briefly intersect with several other trails within the San Juan National Forest. These include sections of the Tamarron, Meadow Trail, Engineer Mountain Trail, Aspen Loop Trail, Mitchell Lakes Road, Cascade Creek Road, Elbert Creek Trail (512), Bears Ranch, and Goulding Creek Trail.
Given the difficulty and high-alpine environment, it's crucial to be well-prepared. Bring plenty of water and snacks, appropriate cycling gear, layers of clothing for varying temperatures, sun protection, a bike repair kit, and a first-aid kit. A fully charged phone and a navigation device are also highly recommended.
The route itself, particularly the climb to Coal Bank Pass, is in a remote mountain area with limited services. It's best to carry all necessary food and water for the duration of your ride. Hermosa and Durango will have amenities, cafes, and pubs for cyclists before or after your ride.
Coal Bank Pass sits at an elevation of 10,610 feet (3,234 meters).
No, this route is not suitable for beginner touring cyclists. It is rated as "difficult" and requires "very good fitness" due to significant elevation gain and steep grades. Beginners should look for less challenging routes within the San Juan National Forest.
