Gros Ventre Wilderness, Nature reserve in Sublette County, United States

Gros Ventre Wilderness is a protected area in Bridger-Teton National Forest, Wyoming, covering most of the Gros Ventre Range. Under the 1964 Wilderness Act no roads or buildings are constructed and no logging or mining takes place, so the land stays as open mountain terrain.

The Gros Ventre Wilderness lies in Bridger-Teton National Forest, and most of the Gros Ventre Range falls inside it. Its name is French for "big belly". Federal protection came with the 1964 Wilderness Act, which barred roads, buildings, logging and mining and closed the area to motorized and mechanized vehicles, bicycles included.

The name comes from French: gros ventre means "big belly" or "big stomach", a name given by French-speaking trappers and traders. Today the wilderness lies in Bridger-Teton National Forest, and hunting is allowed in season, as in other national forest wilderness areas.

The area has multiple entry points and trails suited for different fitness levels and abilities, whether you want a short walk or a long trek. You should prepare for changing weather and alpine conditions, especially in the higher elevations.

The name comes from French, in which "Gros Ventre" means "big belly" or "big stomach"; the pronunciation is groh-VAHNT. The wilderness lies in Bridger-Teton National Forest, and most of the Gros Ventre Range falls inside its boundary.
