Torrey to Gillette Drive: Epic Utah-Wyoming Road Trip Guide

Utah State Route 24 begins in Torrey at the junction with Scenic Byway 12, a road once dubbed 'the most scenic in America' by the American Automobile Association. This 620-mile journey to Gillette, WY crosses the Colorado Plateau, the Green River Basin, and the high plains of Wyoming, ending just shy of the Powder River Basin.

You'll follow US-191 for much of the route, a two-lane highway that cuts through Flaming Gorge National Recreation Area and the Ashley National Forest. The driving time is roughly 10 hours without stops, but plan for at least two full days to absorb the landscapes.
