Montana's stunning freshwater lake situated just south of Glacier National Park

Flathead Lake is the largest natural freshwater lake in the western United States, located south of Glacier National Park in northwest Montana. Renowned for its remarkably clear waters, the lake is a popular destination for swimming, boating, fishing, and lakeside camping. Although frequently included on regional travel itineraries, it is situated outside Glacier National Park's official boundaries.

Quick tip: Explore state park units along the shore like Wayfarers or West Shore for public boat launches and scenic beaches.
