About

Killpecker Sand Dunes OHV Area is a BLM open-riding zone within one of the largest active dune fields in North America, located in Sweetwater County near Rock Springs, Wyoming, accessed via Tri-Territory Road (County Road 4-17) off US-191 approximately 12 miles north of Rock Springs. The Killpecker Dunes extend over 100 miles in length: the OHV-open area covers roughly 11,000 acres of the central dune complex, with dunes reaching 100 feet in height and providing the kind of large-scale dune riding terrain more commonly associated with Oregon's Oregon Dunes or California's Glamis. Novice riders explore the flatter interdune areas and smaller dune faces; experienced riders tackle the large dune crests and steep face descents. All OHV types are permitted at no charge; Wyoming OHV registration is required. All OHVs must display a 8-foot safety flag whip for visibility over dune crests, this rule is non-negotiable and enforced. No permanent facilities on site; Rock Springs (12 miles) provides fuel, food, and camping supplies. Dispersed camping is allowed within the BLM area. High winds are frequent and can create blowing sand conditions; check weather forecasts before extended trips. Contact the BLM Rock Springs Field Office (307-352-0256) for current conditions.
