Embark on a challenging mountain biking adventure with the Engineer Mountain and Colorado Trail Loop, a difficult 40.1 miles (64.5 km) route that demands 6648 feet (2026 metres) of elevation gain. This high-alpine journey will take you through diverse terrain, from dense aspen and spruce-fir forests to wide-open sub-alpine meadows. You will experience the thrill of reaching elevations above 11,000 feet, where panoramic views of the San Juan Mountains, including the majestic Needle and Grenadier ranges, unfold before you. Expect a full day on the saddle, with an estimated duration of 7 hours and 5 minutes to complete this demanding loop.
Planning your ride requires careful consideration, as this trail is best suited for experienced riders. While the south-facing slopes can be accessible in late spring, be aware that high-alpine sections may still hold snow into mid-summer or become muddy after rain. Many riders choose to arrange a shuttle to help manage the significant elevation changes and maximize the downhill portions of the route. Always check current trail conditions before you head out, especially if you plan to ride early or late in the season.
This loop offers a quintessential high-alpine mountain biking experience within the San Juan National Forest. As you navigate the route, keep an eye out for vibrant wildflowers, particularly in July and August, adding splashes of color to the landscape. The trail passes notable landmarks such as Molas Pass and Little Molas Lake, providing distinct points of interest along your journey. Its proximity to Durango also makes it a convenient, yet remote-feeling, option for a truly epic ride.
