The White Wash Sand Dunes are located 48 miles northwest of Moab, and 25 miles southeast of Green River. The Sand Dunes themselves are delineated and fenced for open OHV play; cross country travel is allowed only in the open area. Outside this area, there are hundreds of miles of designated roads and trails to be enjoyed. All motorized travel outside the open area must stay on the designated routes. Staying on the designated routes helps keep these routes open for your enjoyment. Damage to adjoining private property has occurred, and is a threat to your continued enjoyment of this area. Staying on designated routes assures that you will not trespass on private property. Please avoid the oil production facilities and the adjoining ranch, and never chase or harass livestock. When going through gates, leave them open or closed as you found them. You must stay on designated roads and trails when riding outside the dune area. These routes are marked with white arrows and/or white paint. Bighorn sheep inhabit this area; riders should avoid stressing these animals by giving them the space they need. The cottonwood trees growing in the White Wash area are quite unique. Please avoid damaging these trees -- give them wide berth to reduce potential for soil compaction.
