Gallatin County, Near West Yellowstone
Just outside the western boundary of Yellowstone National Park, Hebgen Lake is a large impoundment on the Madison River. Surrounded by the dense coniferous forests of the Custer Gallatin National Forest, the lake is a critical staging area for waterbirds moving through the high country.
The lake is recognized as an Important Bird Area for its population of Trumpeter Swans, which can be found here year-round, utilizing the open water near the inlet of the Madison River during the winter. In the summer, the deep waters of the lake attract breeding Common Loons and Western Grebes. The forested shorelines are excellent for observing forest birds, including Red Crossbills, Pine Grosbeaks, and the occasional Great Gray Owl hunting in the dense timber.
Visitor Access
Access to the lake and the surrounding US Forest Service land is generally free, though fees apply for the developed campgrounds like Rainbow Point. Highway 287 follows the north shore, providing excellent viewing opportunities from the road. A food storage order is in effect from March 1 onwards to ensure safe coexistence with grizzly bears. Specific temporary closures may occur for trail reconstruction or road maintenance.
