Golden to Mt. Evans via Juniper Pass

It is crucial to note that the Mount Blue Sky Scenic Byway (CO 5) is closed for all of the 2025 season due to roadway construction. Both motorized and non-motorized travel, including biking, are prohibited from September 2024 until Memorial Day weekend 2026. Cyclists planning this route should confirm current road status before attempting the ride.

This route is considered one of the most difficult road cycling climbs in Colorado, and even in North America. The primary challenge comes from the sustained climbing and, most significantly, the extreme altitude. As you ascend above 12,000 feet, the air becomes considerably thinner, making breathing and exertion much harder. It's rated as 'difficult' and is best suited for experienced cyclists.

When the Mount Blue Sky Scenic Byway is open, the best time to cycle is typically from late spring (after Memorial Day weekend) through early fall, before the first significant snows. However, weather conditions can change rapidly at high altitudes, even in summer. Early starts are recommended to avoid afternoon thunderstorms, and you should always be prepared for wind, rain, hail, or even snow.

While there are no specific cycling permits for the Arapaho National Forest itself, when the Mount Blue Sky Scenic Byway is open, there may be fees associated with accessing the upper portions of the road, particularly for vehicles. Cyclists should check the latest regulations for the Mount Blue Sky Scenic Byway (formerly Mount Evans Scenic Byway) regarding any potential entrance fees for non-motorized users, especially for the 2026 season and beyond.

To start this challenging ride from Golden, you can typically find parking in various public lots or on-street parking areas within the city. Many cyclists choose to park near the base of Lookout Mountain to begin their ascent. Always check local parking regulations and signage.

The ride is characterized by relentless climbing on generally paved roads. While some sections are smooth, others, especially at higher elevations on Mount Blue Sky, can be rough with expansion ruts. You'll experience diverse ecosystems, from open ponderosa and juniper hills to thick spruce forests, and eventually a stunning alpine environment above the timberline.

This route offers incredible scenery and several notable landmarks. You'll pass through Juniper Pass, enjoy views of alpine lakes like Echo Lake, and eventually reach Summit Lake. The ultimate highlight is reaching the Mount Blue Sky (Evans) Summit, which is the highest paved road in North America.

While the Arapaho National Forest generally allows dogs on trails, this specific road cycling route is not typically considered dog-friendly due to the nature of road cycling, high speeds, and traffic (when the road is open). It's best to leave your furry friends at home for this particular adventure.

Given the extreme altitude and remote nature of parts of this route, it's essential to be self-sufficient. You should bring ample water and food, as services are limited past Echo Lake. Layers of clothing are crucial for rapidly changing weather, including a windbreaker and rain gear. A repair kit, spare tubes, and a first-aid kit are also highly recommended. Don't forget sun protection and a fully charged phone.

Yes, the route intersects with or runs alongside several other paths. Notably, it covers a significant portion of the ADT - Colorado C - Q - Seg 4 and also passes through sections of the Gennessee Bike Trail, Mestaa' Ehehe Pass Central Road, and the Pioneer Trail, among others within the Arapaho National Forest.

This route is renowned for several reasons: it leads to the highest paved road in North America, offering an extreme high-altitude cycling experience. The journey provides spectacular alpine scenery, transitioning from lush forests to rugged tundra with abundant wildlife. Despite its immense difficulty, the stunning vistas and the sense of achievement make it a highly rewarding and memorable ride, often cited as a 'must-do' climb for serious cyclists in Colorado.
