Mount Blue Sky (Evans) to Juniper and Mestaa'Ėhehe Passes loop — Gravel

This route is specifically designed for gravel cycling. While some sections are paved, significant portions are unpaved or compacted gravel. A standard road bike with narrow tires would struggle. We highly recommend a gravel bike with wider tires and a robust frame for the varied terrain.

No, this loop is considered challenging due to its significant elevation gain (over 2,400 meters) and mixed terrain. It traverses high-altitude passes and requires good to very good fitness. Some segments may even require you to push your bike. It's best suited for experienced gravel cyclists.

The route features a combination of asphalt, compacted gravel, and unpaved sections. You'll encounter open ponderosa and juniper hills, sprawling meadows, deep spruce forests, and magnificent alpine environments. The mixed surfaces require a versatile bike and good handling skills.

The best time to cycle this high-altitude loop is typically from late spring through early fall, once the snow has melted and before winter conditions set in. However, weather can be volatile at high altitudes any day of the year, so always check forecasts and be prepared for wind, rain, lightning, or even snow.

While the route passes through the Arapaho National Forest, general cycling on the roads and trails typically does not require a specific permit. However, if you plan to access areas that usually require timed entry or reservations (like the Mount Blue Sky Scenic Byway when it's open), be sure to check current regulations. Always consult official sources like usda.gov for the latest information.

Yes, the Mount Blue Sky Scenic Byway (Colorado Highway 5) from Echo Lake to the summit is closed to all travel, including biking, for improvements. This closure began in September 2024 and is expected to last through all of 2025, with a scheduled reopening on Memorial Day weekend 2026. While the Juniper and Mestaa'Ėhehe Passes portion of the loop may still be accessible, a full ascent to the Mount Blue Sky summit via the byway is not possible during this period.

This loop offers spectacular vistas. You'll pass by Echo Lake and Summit Lake, traverse Juniper Pass and Mestaa'Ėhehe Pass Summit, and get views towards the Mount Blue Sky (Evans) Summit. The route also includes sections of Little Bear Creek Road (Gravel), offering panoramic views of the Continental Divide and alpine landscapes.

The area is rich in wildlife. Cyclists might spot mountain goats, bighorn sheep, marmots, and various alpine wildflowers. Keep an eye out for these creatures, especially in the higher alpine environments.

Specific parking details for this exact loop can vary. Given its proximity to Idaho Springs and Echo Lake, these areas are common starting points with available parking. Always check local signage for parking regulations and fees, especially near popular trailheads or scenic byway access points.

Generally, dogs are allowed on trails within the Arapaho National Forest, but they must be kept on a leash. Always practice Leave No Trace principles, including packing out all pet waste. Be aware that high-altitude environments can be strenuous for pets, and wildlife encounters are possible.

This challenging loop typically takes around 6 hours to complete, depending on your fitness level, pace, and how often you stop to enjoy the views. The total distance is approximately 94 kilometers with over 2,400 meters of elevation gain.
