SaveAZTEC’S MOUNTAIN BIKING TRAILS RANKED AMONG THE FOUR CORNERS’ BEST
For the truly adventurous, there is no greater thrill than mountain biking in Aztec’s high desert terrain. These landscapes offer technical slickrock, rocky elevation climbs and tumbling downhills, some of the finest single-track trails in the Southwest.
Aztec offers a wonderful variety of mountain bike trails, but the two stand apart.
At the forefront is the Alien Run, a BLM-protected pro-level bike park of one-direction, 5-, 12- and 19-mile loops set amongst piñon- and juniper-punctuated canyons and massive sandstone outcroppings.
The other must-try is the Mountain View Trails, a 12-mile trail park engineered especially for beginner-to-intermediate skill levels.
