Part of the Alien Run Trail System.
The Black Hole Loop is a 0.2-mile difficult loop within the Alien Run Trail System and is a popular mountain bike ride in the Four Corners area. This loop is accessed from the main Alien Run loop and is slightly more difficult terrain. This loop is primarily used as a biking route.
From the Black Hole Loop, you can re-access the main Alien Run loop and eventually meet back with the parking area.
The three stacked loops of the Alien Run Trail System offer a variety of riding for everyone. Trails flow through smooth dirt arroyos, traverse along slickrock cliffs, and session through natural technical features.
