Frequently Asked Questions

How challenging is the touring bicycle route from Hermosa to Coal Bank Pass?

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.

What is the best time of year to cycle this route?

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.

Are there any permits or entrance fees required to cycle in the San Juan National Forest?

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.

Where can I park to start this cycling route?

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.

Is the route dog-friendly?

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.

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.
