Off Highway Vehicles
Dinosaurland offers great opportunities for exploring by OHV. Numerous multipurpose trails exist in Ashley National Forest and across the high deserts of the Vernal District of the Bureau of Land Management. On Diamond Mountain Plateau, and in Browns Park between Dinosaur National Monument and the Green River, four-wheel-drive enthusiasts can trace the rugged terrain where Butch Cassidy and the Sundance Kid wandered.

Utah State law requires that no one under eight years of age may operate an OHV on public roads, trails, or lands in Utah. The basic direction of Utah State OHV regulations is that all areas and routes are closed unless designated open.
