Killpecker Dunes Open Play Area

The Killpecker Sand Dunes are the largest living dune system in the United States. “Living” refers to the fact that the dunes are ever changing. Winds and shifting sands are constantly exerting their forces on the dunes creating new and varied terrains.

This Wyoming Sand Dunes Area comprises 10,500 acres, with a portion of those dunes open to the public free of charge for ATV use.

The part of dunes that are open to OHV use is a small portion of the larger dune area with the rest of the dunes under various environmental protections.

The Killpecker Dunes are 100 miles long and 40 miles wide in places. Some regions of this dune are part of the Greater Sand Dunes Area of Critical Environmental Concern (ACEC) and Wilderness Study Areas (WSA).

These designations require the BLM to manage the land here so that no irreprable damage is done, this means that no motorized traffic is allowed in the WSA. This is to protect the sensitive environment as well as the animals native to this region.

There is a large herd of rare Desert Elk, the only Desert Elk in North America, that breed in the adjacent Steamboat Mountain and live throughout the dunes. In addition, there are also pronghorn, wild horses and deer.

The Steamboat Mountain area is closed from May 1st to June 30th to protect the birthing elk and deer.

Be Aware:
The OHV open area is a multi-use area that is rich in natural gas. There are pipelines, valves and holding tanks which may get covered or exposed due to shifting sands. Stay attentive and do not tamper with these facilities.
