Moab, UT → St. George, UT

Your 242-mile journey from Moab to St. George takes you southwest through some of Utah's most dramatic landscape transitions, primarily following US Route 191 south and then US Route 160 west before connecting to Interstate 15 near Hurricane. The drive typically takes around four hours and fifty minutes of driving time, making it a manageable half-day adventure that connects two of Southern Utah's most popular tourist destinations. While the route is straightforward and well-maintained, the terrain changes are substantial enough to keep the drive interesting and warrant your attention to the road conditions and driving dynamics at play.

Departing Moab, you'll climb away from the Colorado River valley and cross the Colorado Plateau, experiencing the otherworldly red rock formations that make the region famous. As you travel south on US 191, you'll pass through high desert terrain characterized by juniper and pinyon forests, with the La Sal Mountains creating a dramatic backdrop to your east. The landscape gradually becomes more arid and open as you approach the town of Monticello, and you'll notice the elevation beginning its steady descent from around 4,000 feet toward lower elevations. Once you turn west on US 160, the scenery opens further into expansive desert vistas before you reach the transition zone near Hurricane, where you'll descend into the Virgin River gorge.

The final stretch on Interstate 15 into St. George represents the only true interstate portion of your drive, and you'll notice the landscape becoming increasingly developed with suburban sprawl as you approach the city. This section is also where you'll experience the most dramatic elevation change, dropping significantly as you enter the warmer, lower Mojave Desert environment that characterizes St. George.

The ideal times to make this drive are spring (March through May) and fall (September through November), when temperatures are moderate and visibility is excellent. Summer heat can be intense, particularly in the lower elevations approaching St. George, while winter occasionally brings snow to the higher elevations around Moab that can affect traction and visibility.

Seasonal Driving Considerations

Mountain passes along this corridor can be treacherous from October through May, with chain requirements, road closures, and whiteout conditions at higher elevations. Summer brings its own challenges — afternoon thunderstorms are common above 7,000 feet, and construction season narrows lanes on key highways. Always check pass conditions before departing, and carry emergency supplies during the colder months.
