Vail, Fremont, and Tennessee Pass loop

This challenging road cycling loop typically takes around 7 hours and 35 minutes to complete. However, your actual duration may vary based on your fitness level, the number of stops you make, and weather conditions.

No, the Vail, Fremont, and Tennessee Pass loop is rated as a "difficult" road ride requiring a very good level of fitness. It involves significant elevation gain (approximately 6,500 feet) and high-altitude riding, with three passes exceeding 10,000 feet. It is not recommended for beginners.

The terrain is varied, featuring dedicated paved bike paths, state highways, and sections with mixed road conditions. You'll encounter newer pavement, but also areas with potholes, fissures, gravel, and debris, especially on Fremont Pass. The Vail Pass Bike Path offers a largely secluded experience, while other sections, like Fremont Pass, may have significant traffic on Highway 91, though a wide shoulder is generally present.

The best time to cycle this high-altitude loop is typically from late spring through early fall, generally June to September, when the passes are clear of snow and weather conditions are most favorable. Be prepared for changing weather, which is common in the mountains, even in summer.

The loop offers breathtaking scenery and numerous points of interest. You'll pass through Vail, enjoy a View of the Valley, and ride the Vail Pass Bike Path. Other highlights include Vail Pass, Copper Mountain, Clinton Gulch Reservoir, Fremont Pass Summit, and the Tennessee Pass – Continental Divide & 10th Mountain Division Memorial. The route also features the historic Camp Hale and the impressive Red Cliff Bridge.

Yes, the climbs vary significantly by direction. For example, climbing Fremont Pass from Copper Mountain (south) is a substantial 1,750-foot gain over 6.5 miles with sustained grades up to 8%. In contrast, climbing Tennessee Pass from Leadville is considered shorter and easier. Be prepared for these directional differences and plan your energy accordingly. Always carry sufficient water and snacks, as services are sparse between towns.

While the loop can be started from various points, Vail is a common starting point. Parking options are available in Vail, though specific trailhead parking for this extensive loop isn't explicitly detailed. Given the length and difficulty, planning your start and end points, potentially with support, is advisable. There are no specific shuttle services mentioned for this entire loop, but local transit might connect parts of the route.

This is a demanding road cycling route that often shares roads with vehicular traffic and includes dedicated bike paths. While dogs are generally allowed on leash in many outdoor areas, the length, difficulty, and road conditions of this specific loop make it generally unsuitable for bringing dogs along, especially for their safety and comfort.

No, there are no specific permits or entrance fees required to cycle the Vail, Fremont, and Tennessee Pass loop itself, nor for passing through the Camp Hale-Continental Divide National Monument on this route. However, always respect local regulations and Leave No Trace principles when recreating in these areas.

Yes, the route intersects with and utilizes sections of several other trails. Notably, it includes portions of the Colorado Trail (segments 7, 8, and 9), the Tenmile Recpath, and the Gore Valley Trail. You'll also encounter parts of the Continental Divide Trail (CDT) and the Fremont Pass Recreational Pathway.

Given the high altitude, significant distance, and potential for changing weather, you should bring plenty of water, energy-rich snacks, and layers of clothing suitable for varying temperatures. Sunscreen, sunglasses, a helmet, a bike repair kit, and navigation tools are also essential. Services are limited between towns, so self-sufficiency is key.
