As the largest freshwater lake west of the Mississippi, Flathead Lake is a true inland sea. Spanning roughly 28 miles long and 14 miles wide, these waters offer a world-class fishery against the backdrop of the Mission Mountains.
Flathead is home to a diverse ecosystem, including:
Lake Trout (Mackinaw), Bull Trout, and Northern Pike.
Cutthroat Trout, Small & Largemouth Bass, Yellow Perch, and Lake Superior Whitefish.
We specialize in trolling and jigging specifically for trophy Lake Trout. However, the lake is your playground—we are more than happy to chase the species of your choice!
From trophy Lake Trout to scenic fly fishing rivers, we’ll guide you to Montana’s best fishing experiences.
