Embark on the Government Trail and Buttermilk Mountain Loop, a moderate mountain biking adventure spanning 13.8 miles (22.1 km). This route challenges you with a significant 2304 feet (702 metres) of elevation gain, typically completed in about 2 hours and 20 minutes. You will ride through vibrant aspen groves and open, flower-filled meadows, experiencing a mix of smooth trail and technical singletrack sections, including rocky gardens and root-laden paths. As you climb Buttermilk Mountain, you are treated to sweeping vistas of the Maroon Creek valley and the majestic Pyramid Peak.
Before you go, be aware that a section of the Government Trail closes seasonally for elk calving, usually from mid-May through late June, so check local conditions. While you can ride the loop in either direction, many riders prefer starting from Snowmass and heading towards Buttermilk or Aspen to maximize the downhill segments. This approach makes for a more exhilarating ride, especially if you are an intermediate to advanced mountain biker looking for a rewarding experience.
This loop is celebrated for its dynamic terrain and the stunning natural beauty of the White River National Forest. It offers a true taste of high-country riding, combining physical challenge with breathtaking scenery. The trail's design ensures a varied experience, from steady climbs that test your endurance to technical descents that hone your skills, all set against the backdrop of the iconic Roaring Fork Valley.
