Description

Sunnyside connects the trails of Hunter Creek and 4 Corners areas down to the paved Rio Grande bike path. The trail offers challenging riding on narrow trails, traversing and descending steep terrain while distracting you with big mountain views. Many rocky sections will test your expert level riding skills.

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.

View from Red Mountain, traversing it's face on the Sunnyside trail.

This is pretty mush the start of the huge descent down Sunnyside Trail.  In the distance, you can imagine where the trail traverses along the face of Red Mt. in the aspen groves, and where Shadyside Trail might be in the dark timber area.

Sunnyside Trail, always a worthy destination when the aspen leaves change color!
