Land OwnerUSFS
Good trail in both directions. Connections to Aspen Alley and the main West Mag parking area. Rolling easy to moderate singletrack trail recently rerouted by Boulder Mountainbike Alliance per the Magnolia Trails Plan recently approved by the USFS. The view from the top of this trail is amazing and a worthy point to stop and and take in the surrounding area including Eldora Ski Area and the Continental Divide beyond. Nothing technical but a little bit of exposure in the middle section. Keep your eyes up while climbing as downhill speeds can be fast.
