Need to Know
Little to no shade is available on the trail, so be prepared for sun and heat. Follow all trail signs to avoid ending up on bandit trails or private property.
If running on the higher portions of the trail, be aware that it becomes fairly technical with multiple outcroppings of rocks jutting onto the trail.
The Sunnyside trailhead is directly off of McLain Flats Road, with a 10± vehicle parking lot on the opposite side of the road.
Starting with a relatively low grade, the trail grows steeper soon after beginning and is then a long, steady zig-zag climb to the finish, with the exception of a flat traverse of about a quarter mile. Obvious directional signage is present along the entire trail. The beginning of the trail has slight Aspen tree coverage, transitioning into low brush. Most people run only as far as the small radio tower, which is a natural stopping point in a quiet Aspen grove, before returning to the trailhead.
From the trail, there are sweeping views from Independence Pass to all four of the Aspen/Snowmass ski mountains and the high peaks in between. Be sure to bring your camera along so that you can make all of your friends jealous.
