The Thompson Chain of Lakes, nestled in Montana’s picturesque Glacier Country region, offers nature enthusiasts and vacationers a serene retreat. Stretching for 20 miles along US Highway 2, about 45 miles south of Libby, this chain of glacial kettle lakes includes notable bodies of water such as Loon Lake, Horseshoe Lake, Crystal Lake, Upper Thompson Lake, Middle Thompson Lake, Lower Thompson Lake, and McGregor Lake. These lakes, primarily fed by springs and ground seepage, serve as the Fisher River’s headwaters, a tributary of the Kootenai River system.
This area, named after land surveyor David Thompson, who first documented it in 1811, has long been a coveted spot for those seeking a tranquil escape. The lakes are surrounded by a mix of wetlands, marshes, and forests, making the region rich in biodiversity. Wildlife like loons, whitetail deer, mule deer, and elk, along with various songbirds, are frequently seen. The lakes provide excellent fishing opportunities, with species such as cutthroat trout, brown trout, rainbow trout, brook trout, yellow perch, kokanee, largemouth bass, smallmouth bass, northern pike, mountain whitefish, and pumpkinseed. The trout are stocked annually, and fishing enthusiasts can enjoy summer and winter activities, including an ice fishing tournament on Lower Thompson Lake.
Recreational activities abound in the Thompson Chain of Lakes. While Middle Thompson and Upper Thompson Lakes are no-wake zones, McGregor Lake is open for water sports like skiing. The area boasts several campgrounds, including Logan State Park on Middle Thompson Lake, which offers 83 campsites, picnic tables, fire rings, vault toilets, drinking water, a swimming area, and a boat launch ramp. There are nine state’ fishing access’ boat launch sites, and primitive campsites are scattered along Lower, Middle, and Upper Thompson Lakes and Horseshoe and Loon Lakes.
Hiking and nature walks are popular, with a designated 2.9-mile trail at McGregor Lake. The area is also known for its excellent huckleberry picking. While the roads in the area are rough and unsuitable for motor homes or low-clearance vehicles, walking or bicycling on gravel roads can lead to most lakes. The area’s beauty is complemented by the surrounding Cabinet Mountains to the south and the Salish Mountains to the north, offering additional hiking trails and lookout points.
For those seeking more substantial lodging, there are resorts on Crystal Lake, McGregor Lake, and some of the other lakes. These are often geared towards fishing, with guides and supplies available. Despite the remote and serene setting, basic amenities such as small convenience-style stores can be found in the area, while more comprehensive services are available in Libby and Kalispell. This region, with its mix of serene lakes, abundant wildlife, and recreational opportunities, is an ideal destination for a relaxing getaway.
