Logan to Big Sky Road Trip: Ultimate Guide to Scenic Drives

This route traces the western edge of the Rocky Mountains, crossing the Bear River Range and the Caribou-Targhee National Forest. The drive covers approximately 280 miles via US-89 and US-191, taking about 5 hours without stops.

One unusual fact: near Montpelier, Idaho, you'll cross the Bear River, which is the largest tributary of the Great Salt Lake. The river's unique chemistry makes it a prime spot for migratory birds, but also creates occasional fog patches in early mornings.
