Blanding to Big Sky Road Trip: Epic Utah to Montana Drive

The route from Blanding, Utah to Big Sky, Montana traverses nearly 700 miles of some of the most iconic landscapes in the United States. The stretch from US-191 to I-15 and then I-90 covers four states and a dramatic shift from red rock desert to alpine peaks.

A local driving quirk: on US-191 between Blanding and Moab, you'll encounter the "Valley of the Gods"—a 17-mile gravel loop that offers stunning views but is impassable after rain. This road trip is not just a drive; it's a journey through geological epochs.
