Land OwnerPitkin County Open Space & Trails
This bike optimized flow and jump trail was constructed in 2014, and has been refreshed every 5-6 years since then. It is managed as a downhill directional only trail given the many jumps along the trail. Access the trail from the top of the Viewline trail at western end of Skyline Ridge trail. With the opening of Deadline, Viewline trail is now recommended for uphill bike travel
This trail is another first of its kind for the Aspen / Snowmass area. It's a bike optimized directional flow trail that features large, generous in-sloped berm turns, rollers, table top jumps, drop offs, and a couple doubles that can be easily gapped at speed. The width of the trail and ability to roll over just about every one of the jumps (if you slow down enough) gives this trail an intermediate rating. At full speed, the trail is definitely in the expert/difficult category. While the views towards Snowmass and the forests of the Government Trail are excellent, your eyes will mostly be focused on the trail
Use this trail as part of a tour of Sky Mountain Park, or part of a longer ride linking Airline Trail to Skyline Ridge trail to Deadline trail to Highline trail to Tom Blake trail to Powerline to Government Trail. Or, park at the Rodeo Lot or smaller parking lot along Owl Creek Road and take multiple laps on Viewline trail - Deadline Trail - Highline trail.
