“One of Aspen's premier classic trails, offering big views and challenging riding.”— Mike Pritchard
On the upper reaches of the trail, look out for the Shadyside Trail for optional routes and additional mileage.
The trail is adopted by the Aspen Cycling Club, which conducts annual maintenance work to keep the trail in shape.
Sunnyside is popular with hikers, especially on the lower slopes. Please yield and be polite whenever possible. Given the steep technical nature of the trail, it's recommended for downhill bike travel only.
Just before the final lowest segment of trail, you'll cross over the paved McLain Flats Rd. (parking available here). Watch out for fast vehicles before crossing over to the final segment, which links to the Rio Grande trail. Make a left to go towards Aspen.
