2. Doctor Park, Almont, Colorado
Distance: 9.6 miles
Technical Difficulty: Intermediate to Advanced
Endurance: 7 out of 10
Though the epic riding in Crested Butte, 20 miles up the road, often overshadows this outlier, Doctor Park holds its own against classics such as the 401, 403, and Teocali Ridge. After a grunt of a two-track climb to 10,900 feet, on the flank of Manganese Mountain, the ride turns to blessedly narrow, ingeniously constructed single track that slams 2,600 feet down to the Taylor River. It comes in three distinct parts: a top section through thick pines and sharp root drops, a flowing middle on buffed-out smooth, and a rugged bottom that picks through fangs of rock.
Logistics: You can shuttle up Forest Road 744, but full value is to park at Taylor Canyon Campground, on the road east of Almont, and make a 19-mile loop of it. For maps and support, Rock ‘N’ Roll Sports is 10 miles south in Gunnison.
