Moab to Big Sky Road Trip: Ultimate Guide to Scenic Stops

The drive from Moab, UT to Big Sky, MT covers approximately 600 miles via US-191, I-70, US-40, US-191, and US-287. What many don't realize is that this route crosses the Continental Divide twice—once near Rawlins, WY and again near West Yellowstone. The elevation gain from Moab's 4,000 feet to Big Sky's 8,000 feet is a steady climb that transforms desert air into crisp mountain pine.
