Big Arm, MT

Located on the "big arm" of Flathead Lake, the aptly named community of Big Arm provides incredible lake views and close proximity to Wild Horse Island. Big Arm State Park offers camping, hiking, biking, wildlife watching and a long pebble beach that's popular with swimmers and sun soakers. Lake life on the Big Arm Bay means sailing, scuba diving, water-skiing and lake-trout fishing are all right outside your door.

Insider Tip

Wild Horse Island is open for day-use—only reachable by boat—and is a wonderful place to have a picnic and spend the day hiking.
