In 2009, the U.S. Congress designated nearly 19,000 acres as the Red Mountain Wilderness, which is located just north of St. George between Snow Canyon and Gunlock state parks. Here, mountain peaks sporadically poke up from the upland plateau. There are no roads and only a handful of casual trails, most of which are located on the east side. To make the most of your visit, take the Red Mountain Trail, which runs just under 10 miles from one end of the wilderness area to the other. Parts of the trail skirt the western lip above Snow Canyon, offering incredible views of the surrounding landscape.
