Rugged, mountainous, and breathtakingly beautiful, northwest Montana is an underrated treasure. While Glacier National Park offers unparalleled access to outdoor recreation and stunning scenery, it’s far from the only gem in that corner of the Treasure State.

The Lake Koocanusa Scenic Byway is a short, sweet road trip that takes you from Libby to Eureka (or vice versa). This is one of northwest Montana’s best-kept secrets, and it’s definitely worth the drive.
