Les Mason State Park is a compact eight-acre day-use recreation area on the east shore of Whitefish Lake, roughly four miles north of Whitefish, Montana. Focused on easy access to the lake and shoreline, it features a 585-foot sand and gravel beach, short walking trails, and picnic areas. Swimming and canoeing are among its main attractions, making it a simple summer destination centered on lakeside use rather than backcountry amenities or overnight camping.
