About Custer-Gallatin National Forest

Custer-Gallatin National Forest is a vast expanse of wilderness in Montana and Wyoming, known for its diverse landscapes and abundant outdoor recreation opportunities.

Wilderness Landscape & Natural Heritage

Custer-Gallatin National Forest, sprawling over approximately 3 million acres across Montana and Wyoming, is a haven for outdoor enthusiasts. The forest encompasses a wide range of landscapes, from the majestic peaks of the Absaroka-Beartooth Wilderness to the rolling prairies and dense forests, providing a patchwork of ecosystems supporting diverse wildlife, including grizzly bears, wolves, and elk. Historically, the area has been significant for Native American tribes and played a role in the expansion of the American frontier. Recreational opportunities abound with hundreds of miles of trails catering to hikers, mountain bikers, and horseback riders. In winter, the snowy landscapes transform into a playground for skiing and snowshoeing. Noteworthy landmarks such as the iconic Beartooth Highway offer breathtaking scenic drives, while the site of the Battle of the Little Bighorn offers a window into the region's rich history.
