Lake Koocanusa scenic byway is located in northwestern Montana, northeast of Libby. The byway forms a loop drive around Lake Koocanusa between Libby and Eureka. It is 88 miles long and follows MT 37 and FSR 228, which are two-lane paved roads suitable for all vehicles. Temporary closure is possible during winter, otherwise the byway remains open year-round.

The Lake Koocanusa scenic byway travels across Kootenai National Forest through ponderosa pine, lodgepole pine, and Douglas fir. The lake for which the byway is named is a 90-mile long reservoir reaching into Canada. It was created by the construction of Libby Dam. Many scenic turnouts provide excellent views of the lake and surrounding mountains. A visitor center at the dam provides information and guided tours of the 370-foot high structure.

Excellent fishing in the lake has given the area a reputation as one of the best salmon fisheries. The lake and Kootenai River below the dam provide excellent opportunities for catching rainbow, westslope, cutthroat, bull trout, kokanee salmon, and brook trout.

Several recreation areas are located along the byway. Rocky Gorge has 120 campsites suitable for tents and recreational vehicles. A boat ramp gives access to the lake. Peck Gulch has restrooms, a boat ramp, and plenty of sites for picnicking or camping. The Barron Creek Recreation Site has a boat ramp and dispersed camping areas. McGillivray Recreation Site is a campground and day use area with group picnic shelters. Overnight camping, ball fields, a swimming beach, and a boat ramp are available. A short boat ride from this recreation area will take you to Yarnell Islands, which have camping and picnicking facilities.

Numerous side roads invite further exploration of Kootenai National Forest. The forest offers a total of 35 camping areas with over 600 campsites. Dispersed camping is also permitted nearly anywhere on public lands. Five national recreation trails are within the national forest for those interested in hiking or backpacking. Little North Fork Trail is near the byway and guides you to a scenic waterfall.
