This route was planned by komoot.
The full loop is approximately 22.3 km (13.6-14 miles) and komoot estimates a duration of around 2 hours and 40 minutes for mountain biking. However, due to the strenuous climbing, high altitude, and technical sections, many riders find it takes longer, often 3-4 hours or more, depending on fitness and skill level.
The trail offers a diverse riding experience. It begins with a significant and steep climb up a gravel road, followed by an even steeper singletrack ascent through dense trees. While much of the singletrack is smooth and fast, you'll also encounter chunky, rutted, or technically demanding sections, especially in the latter half. Expect narrow trails, switchbacks, occasional rocky sections, and potential stream crossings. Even in mid-August, snowfields can be present at higher elevations.
The 401 Trail Loop is famous for its breathtaking alpine views. You'll be treated to sweeping vistas of Colorado's Elk Range, high-alpine lakes, and the majestic Mount Crested Butte. During mid-summer, the meadows are vibrant with wildflowers, and in the fall, the trail winds through stunning golden aspen groves.
No, the 401 Trail Loop is generally rated as intermediate to advanced, or 'intermediate plus.' This is primarily due to the strenuous climbing, high altitude, and technical features on the descent. Beginners may find the sustained climbs and some exposed or rocky sections challenging. E-bikes are also not permitted on this trail.
The best time to ride is typically mid-summer through early fall. Mid-summer offers incredible wildflower displays, while fall brings vibrant golden aspen colors. Be aware that snowfields can persist at higher elevations even into August, and the trail is usually only clear of snow from late June or early July until the first significant snowfalls in the autumn.
The 401 Trail Loop is located near Crested Butte, Colorado. The primary access point is often from the area around Schofield Pass Road. Parking is available, but it can fill up quickly, especially on peak summer weekends. Arriving early is highly recommended.
