Smuggler Mountain Road This ride begins with a hard climb and leads to an awesome gateway of multiple loops in the Hunter Creek Valley.
Sky Mountain Park This recently acquired open space property lies on the ridge between Brush Creek and Owl Creek, above the airport. Many different routes sprawl on perfectly-graded modern trails. Views of Aspen, Independence Pass, Snowmass and the rugged Elk Mountains abound. Really awesome and totally worthwhile.
Snowmass ski area has extensive lift-served downhill and cross country mountain biking trails. Downhill bikes are available for rent.
Road Bike Castle Creek Road to Ashcroft and Maroon Creek Road to the Maroon Bells are a pleasure to climb with little auto traffic. Each trek is about 10 miles, one way. There is a reason many professional riders live in Aspen.
INSIDER TIP Park at Snowmass Recreation Center. Ride uphill on the East Rim Trail 3 miles. Turn right at 7 Star Trail for 5 miles of perfect downhill rolling.
