Key Points:

  • Bridger-Teton National Forest is Wyoming’s largest forest, covering 3.4 million acres.
  • The forest houses three substantial United States Wilderness Areas: Gros Ventre, Bridger, and Teton Wilderness Areas.
  • The combined area of these wilderness areas amounts to 1.2 million acres within the Bridger-Teton National Forest.

Wyoming is in the Mountain West subregion of the United States. It shares a border with Colorado to the south, Utah to the southwest, Idaho to the west, Nebraska and South Dakota to the east, and Montana to the north. Although Wyoming is the 10th largest state by area, it is the least populated. With so much land and so few people, Wyoming is a great place for those seeking backcountry experiences. What’s more, 53.6% of the land in Wyoming is public.

The state contains 27,860 square miles of Bureau of Land Management (BLM) land, 14,460 square miles of United States Forest Service (USFS) land, and 5,500 square miles of state land.

That’s over 30 million acres of public land! Wyoming has some large and incredible forests, especially within its iconic national parks like Yellowstone and Grand Teton. But what is the largest forest in Wyoming?

The Largest Forest in Wyoming: Bridger-Teton National Forest

At 3.4 million acres, the Bridger-Teton National Forest is the largest forest in Wyoming. Bridger-Teton National Forest contains three large United States Wilderness Areas. These are the Gros Ventre, Bridger, and Teton Wilderness Areas, and together they total 1.2 million acres. United States Wilderness Areas do not allow logging, mining, motorized vehicles, or development. People can access these areas to hike, camp, backpack, hunt, fish, or ride horses. However, it is important that people follow “leave no trace” principles when visiting.

Bridger-Teton National Forest has Wyoming’s tallest mountain, Gannett Peak. It also has over 40 other mountains over 13,000 feet tall. Since the forest contains a lot of high-elevation land, it receives a lot of snow. In fact, some places in Bridger-Teton National Forest get over 600 inches of snow per year!

The Wind River Mountain Range, much of which is in Bridger-Teton National Forest, has 25 glaciers. Bridger-Teton National Forest also contains the headwaters of the Yellowstone, Green, and Snake Rivers.

History of Bridger-Teton National Forest

Bridger-Teton National Forest has many lakes, rivers, and creeks due to heavy snowfall.


Bridger-Teton Forest has a long natural and human history. There is evidence that humans have inhabited the area now called Bridger-Teton Forest for over 10,000 years. The early humans who lived in this area were nomadic hunters and gatherers. The Bridger-Teton National Forest is a part of the ancestral lands of the Eastern Shoshone and Shoshone-Bannock tribes. European fur trappers first arrived in the area in 1807. Several rivers, creeks, and forks in the forest were later named by settlers after men who were early fur trappers. Settlers began setting up permanent residences in the area in the late 1800s.

The Bridger-Teton National Forest exists with its current boundaries and name because of a history of renaming and combining forest lands in Wyoming. First, both the Teton and Wyoming National Forests were created in 1908. Then, the Wyoming National Forest was renamed Bridger National Forest in 1941. Lastly, in 1973, the Bridger and Teton National Forests were combined to create the largest forest in Wyoming: Bridger-Teton National Forest.

Wolves in Yellowstone National Park are still protected, but those outside the park are designated as predators and can be shot on sight, even without a hunting license. There are around 300 wolves in Wyoming.

Moose (Alces alces)

The yellow-bellied marmot is a species of ground squirrel in the genus Marmota. Marmots are sometimes called “whistle pigs” because they produce a high-pitched whistle noise to alert each other to nearby predators.

Trumpeter Swan (Cygnus buccinator)

The trumpeter swan is the largest species of waterfowl existing today. They are also the heaviest extant bird in North America. Trumpeter swans were almost extinct by the early 1930s, but the population has since been restored to over 46,000 in North America.

Sandhill cranes have the longest fossil record of any extant bird. There is a 2.5 million-year-old sandhill crane fossil and a 10 million years old possible sandhill crane fossil. It is unknown if the 10 million-year-old fossil is a sandhill crane or a prehistoric ancestor.
