Sand Hollow

Sand Hollow State Park's Sand Mountain OHV Area sits approximately 15 miles east of St. George in Washington County, Utah, at an elevation of 3,000 feet on the edge of the Colorado Plateau's Navajo Sandstone formation, one of the closest major OHV destinations to Las Vegas (approximately 120 miles northeast via I-15) in a region that serves the combined St. George, Mesquite, and Las Vegas riding market year-round. The OHV area encompasses 15,000 acres of red sand dune and slickrock terrain within the 20,000-acre state park boundary, creating a landscape that combines the open dune riding character of sand dunes with the technical slickrock navigation challenges that define the Moab-country terrain to the north. The red sand color is derived from the iron-rich Navajo Sandstone that underlies the Colorado Plateau throughout this region: the same geological formation that colors the Zion cliffs and the Bryce hoodoos gives Sand Mountain its distinctive warm-red sand. ATVs, side-by-sides, dirt bikes, and dune buggies are permitted on the OHV area; a Utah state parks day-use pass and Utah OHV permit are required. Sand Hollow Reservoir, within the same state park boundary, provides an adjacent water recreation option. Camping with hookups is available at the park's developed campground. Washington County's mild climate makes year-round riding practical; peak season runs October through April when the St. George area experiences optimal temperatures.
