Echo Lake to Mount Blue Sky (Evans) Summit

This route is classified as difficult and requires very good fitness. The primary challenge comes from the sustained length of the climb and the extreme altitude. While the average grade is around 4.5%, you'll be cycling at elevations where there's significantly less oxygen, making the effort much harder. Acclimation at lower elevations before attempting this ride is highly recommended.

Please be aware that the Mount Blue Sky Highway is undergoing significant construction. It will be closed to all users, including cyclists, from September 3, 2024, through the entirety of 2025. Access to the summit during this period will only be possible via hiking trails. The highway is projected to reopen around Memorial Day weekend 2026. Always check current conditions before planning your trip.

The best time to cycle this route is typically from late spring (after Memorial Day, when the road usually opens) through early fall, before the first heavy snows. However, weather conditions at high altitudes are highly unpredictable and can change rapidly, with possibilities of wind, rain, lightning, snow, and hail at any time of year. Always check the forecast immediately before your ride.

Yes, there is a timed entry reservation system and a fee required to access the Mount Blue Sky Recreation Area, which includes the highway. You can find detailed information and make reservations on the USDA Forest Service website. It's crucial to secure your reservation in advance, especially during peak season.

Parking is available at the Echo Lake Recreation Area. This is a popular starting point for the climb. Be aware that parking can fill up quickly, especially on weekends, so arriving early is advisable. There may also be a fee for parking within the recreation area.

The entire route is paved, but the condition of the pavement can vary. Some sections, particularly in the 14 miles above Echo Lake, may have cracks and potholes. These imperfections can make the descent particularly uncomfortable, so be prepared for a potentially bumpy ride in places.

The route passes through the Mount Blue Sky Wilderness, offering excellent opportunities for wildlife viewing. It's common to spot mountain goats and Rocky Mountain bighorn sheep, especially in the higher, more exposed sections. Keep a respectful distance and do not disturb the animals.

Given the extreme altitude and unpredictable weather, you should bring layers of clothing (including a windproof/waterproof jacket), plenty of water and snacks, sunscreen, sunglasses, and a helmet. A bike in excellent working condition with appropriate gearing for climbing is also essential. Consider a light for tunnels or early/late starts.

The scenery is consistently spectacular. You'll pass by Echo Lake, climb above the tree line, and eventually reach Summit Lake. The route culminates at the Mount Blue Sky (Evans) Summit, offering panoramic views of distant peaks and glacial valleys. Wildlife sightings are also a highlight.

While dogs are generally allowed in the Mount Blue Sky Recreation Area, they must be kept on a leash at all times. Be mindful of the extreme conditions and high altitude, which can be challenging for pets. Always carry enough water for your dog and be aware of their limits.

While the primary route is a paved road for cycling, it passes through the Mount Blue Sky Wilderness, which contains several hiking trails. You'll find nearby trails such as the Chicago Lakes Trail, Mount Evans Spur Road, and the Alpine Garden Loop Trail, though these are generally not part of the cycling route itself.
