Yellow Bay State Park, State park on Flathead Lake shore, Montana

Yellow Bay State Park is located on the eastern shore of Flathead Lake with a wide gravelly beach and direct water access for swimming and boating. The grounds include open grass areas, scattered trees for shade, and a creek running through the property.

The area was established in 1941 by Montana Fish, Wildlife & Parks as part of the larger Flathead Lake State Park system. Its creation provided public access to this shoreline location.

The park lies twelve miles south of Bigfork in Lake County, on the eastern shore of Flathead Lake. Its name comes from the yellow bay, a reference to the yellow hues along this stretch of shoreline. The surrounding hillsides are covered in coniferous forest, and the valley holds very few year-round residents.

The park offers five tent camping sites operating from May through September with restrooms, drinking water, and grilling facilities on site. Plan your visit during these months since the area closes during winter.

The park covers fifteen acres on the eastern shore of Flathead Lake, twelve miles south of Bigfork. The surrounding terrain rises to 1,517 metres within about two kilometres, while the park itself sits at 884 metres.
