Land OwnerPitkin County Open Space & Trails
This trail was constructed in 2013 to provide access to Sky Mountain Park from the Brush Creek Park & Ride (aka Intercept Lot) area and Brush Creek Bike Path. The trail connects with Skyline Ridge trail at its upper end, and intersects with Airline Trail about 3/4 of the way up.
The trail was built by a combination of volunteers, youth corps, and a contractor using a small min-excavator. As such, the character changes a few times along its length. Long gently graded climbs on the up equal fast brake-free flowing sections on the descent. This one is a must-ride for both locals and visitors
