7:15 PM LOCAL TIMEThe San Rafael Swell is a large mountainous anticline and desert basin in south-central Utah, formed by tectonic uplift and relentless erosion by rivers and wind. At about 3,500 square kilometers, it offers a dramatic landscape of slot canyons, natural arches, hoodoos, and layered rock formations, linked by a network of dirt roads and trails. While not as frequented as nearby national parks, the Swell rewards exploration by high-clearance vehicles, mountain bikers, and hikers seeking solitude and raw geology. Key access points include the Little Grand Canyon and the surrounding trailheads; popular activities range from canal hikes and driveable routes to off-road camping and backcountry navigation. Despite its scale and beauty, the Swell remains a remote place where visitors should prepare for changing weather, limited services, and a wilderness ethos.
