Alien Run Trail
Alien Run Trail
Part of the Alien Run Trails System.
Alien Run is a 9.2-mile moderate loop within the Alien Run Trail System and is a popular mountain bike ride in the Four Corners area. This loop is also the first loop of Alien Run’s optional longer routes.
The three stacked loops of Alien Run offer a variety of riding for everyone. Trails flow through smooth dirt arroyos, traverse along slickrock cliffs, and session through natural technical features. The further one rides from the trailhead, the more difficult the trail; the one-way Outer Limits trail is characterized by sections of rocky climbing, plunging downhill sections, and meandering through dune-like terrain.

Ice, mud, snow, and hard sand are the tread conditions. I don’t think it is in good condition. We rode the 5 and 10 mile loops.
