Aspen Fat Bike Loop

About

The Aspen Fat Bike Loop is a winter-focused riding route in Aspen, Colorado, designed specifically for fat bikes. The trail system combines snowmobile-groomed singletrack on the Aspen Golf Course and Maroon Creek Trail with groomed nordic trails and paved or plowed bike paths that link the segments together. While some sources list the loop as 6.1 miles and others as 4.5 miles, the route consistently utilizes the Aspen Recreation Center, Maroon Creek Trail, Aspen Golf Course Trails, Marolt Trails, and Aspen High School paths as key components. The recommended direction is clockwise, which allows riders to ascend on paved or plowed surfaces and descend on snow-covered terrain. The loop starts and ends at the Aspen Golf Course parking lot, with the low point located just south of Highway 82. Parking is available near the trailhead, and pets are permitted. The trail is generally accessible from April through October, though it is primarily a winter ride requiring cold temperatures and packed snow conditions. Riders should check for specific trail closures, as portions of the Aspen Snowmass winter Nordic Trail System are closed to fat bikes, and must ride only where signs indicate bikes are allowed. The difficulty is rated as moderate.
