Montana’s Thompson Chain of Lakes Campground — 37 Sites with Electric Hookups, Salmon & Trout Fishing, Boat Launch, Swimming & Northwest Montana Lakeside Recreation
Logan State Park is a 37-site lakeside campground on the north shore of Middle Thompson Lake, part of the 3,000-acre Thompson Chain of Lakes in northwest Montana. Located just off US Highway 2 between Libby and Kalispell, the park offers camping with electric hookups, flush toilets and showers, a boat launch with reservable boat slips, fishing for salmon, trout, perch, pike, and bass, swimming, a playground, horseshoe pits, and a nature trail.
The Thompson Chain of Lakes — a series of interconnected lakes along the Thompson River — provides a quieter, less crowded alternative to Flathead Lake. Logan’s campground accommodates RVs up to 40 feet with electric hookups and a dump station. The fishing is excellent and diverse — kokanee salmon, rainbow and brown trout, yellow perch, northern pike, and largemouth bass. For visitors exploring northwest Montana’s lake country, Logan delivers full-service lakeside camping without the Flathead Lake crowds.
