The instant you hit Flathead National Forest, you're surrounded by wilderness. This 2.3-million-acre chunk of wilderness, tucked into the northwest corner of Montana, near Kalispell, is bordered by Glacier National Park and three other national forests. That means you can visit snowcapped peaks, alpine meadows, and high-altitude lakes without intrusion from noisy, motorized vehicles. Also tucked in this vast expanse of untrammeled land are 250 species of wildlife, including 22 varieties of fish and 50 birds.
