You're standing on the Strip. It's 110 degrees, the neon is flickering, and your ears are ringing from the slot machines. Then it hits you. You want out. You want red rocks, silence, and the kind of stars you can only see when you're 200 miles from a literal light-pollution factory. Driving from Las Vegas to Moab Utah is a rite of passage for desert rats, but if you just plug it into Google Maps and mindlessly follow the blue line, you’re gonna have a bad time.
Seriously.
The most direct route is basically just a giant "L" shape on the map. You head north on I-15 through a tiny slice of Arizona, cut into Utah, and then hang a right at Spanish Fork to head south. It’s about 450 miles. On paper, that’s six and a half hours. In reality? With road work in the Virgin River Gorge and the inevitable slow-motion truck races on the climbs, it’s a full day’s commitment.
Most people mess this up. They treat it like a commute. They pack a couple of lukewarm waters, hit the gas, and wonder why they feel like a piece of dehydrated jerky by the time they hit the Colorado River. Don't do that.
The Interstate 15 Gauntlet and the Gorge
The first leg of the trek from Las Vegas to Moab Utah is the most stressful. You're fighting traffic leaving Vegas, which, honestly, is a coin toss regardless of the time of day. Once you clear the city, you’re in the Mojave. It’s flat. It’s fast. People drive like they’re auditioning for Mad Max.
Then you hit the Virgin River Gorge. This is the stretch between Mesquite, Nevada, and St. George, Utah. It is stunning. Massive limestone cliffs tower over the road, and the highway snakes right alongside the river. It’s also a bottleneck. If there is a single accident or a construction crew moving a cone, you will be sitting there for forty-five minutes contemplating your life choices. Check the UDOT (Utah Department of Transportation) app before you leave. I'm serious.

Once you pop out of the gorge, you're in St. George. If you’re hungry, stop here. Moab is expensive. St. George has every chain and local eatery you could want. It’s the last "real" city you’ll see for a while. If you need gear—coolers, hiking boots, or a spare tire—get it now.
Why the "Direct Route" Sucks (and What to Do Instead)
If you follow the 1-15 all the way to Highway 6, you’re missing the point of being in the Southwest. You’re driving right past Zion National Park. You’re skirting the edge of Bryce Canyon.
If you have an extra day, or even just an extra five hours, you should take Highway 12. Ask any local road tripper—this is arguably the most beautiful road in America. You’d peel off the I-15 at Cedar City, head toward Panguitch, and then take Highway 12 through Escalante and Boulder. You eventually end up at Torrey and can take Highway 24 into Moab.
It’s longer. It’s winding. It’s terrifying if you hate heights (look up "The Hogback"). But if you want the "real" experience of traveling from Las Vegas to Moab Utah, this is the one. You’ll see the Grand Staircase-Escalante National Monument, which is basically a giant geological staircase of white, pink, and grey cliffs.
The Scofield and Soldier Summit Stretch
Let’s assume you stayed on the fast track. Eventually, you have to leave the I-15. Most GPS units will take you up to Spanish Fork and then dump you onto US-6 East. This is the "Price Road."

It’s a weird stretch of pavement. You climb over Soldier Summit, which sits at nearly 7,500 feet. Your car might struggle if it’s an older model or if you’re hauling a heavy trailer. Watch your temp gauge. This road is notorious for head-on collisions because people get impatient behind slow-moving coal trucks and try to pass on double yellows. Don't be that person. Price is a decent spot for gas, but it’s a rugged, industrial town. It’s not "tourist" Utah. It’s "we work for a living" Utah.
After Price, you hit the desert. Again. But this time it’s the San Rafael Swell.
The Swell is a giant geological uplift—a "wrinkle" in the earth. It looks like another planet. You’ll pass through the Spotted Wolf Canyon on I-70, which was blasted through solid rock. It’s spectacular. There are no services here. None. If you run out of gas between Green River and Salina, you are basically waiting for a kind stranger or a very expensive tow truck.
Green River: The Gateway to the End
You’re almost there. Green River is about 50 miles from Moab. It is famous for two things: melons and the river. If it’s summer, buy a watermelon from a roadside stand. They’re grown in the silt of the river and they’re incredible.
This is also where you jump off I-70 and head south on Highway 191. This is the final stretch of your Las Vegas to Moab Utah journey. The rocks start getting redder. The cliffs get taller. You’ll pass the turn-off for Canyonlands National Park (Island in the Sky district) and Dead Horse Point State Park.

If it’s sunset, pull over at the 191 overlook. You can see the La Sal Mountains—usually capped with snow—towering over the red desert. It’s a contrast that doesn't feel real.
Survival Logistics You Actually Need to Know
Moab is a victim of its own success. It is crowded. From March to October, it’s a zoo.
- Water is life. Not being dramatic. You need a gallon per person per day. The air is so dry your sweat evaporates before you even feel wet. You’re dehydrating and you don't even know it.
- Arches National Park Timed Entry. If you’re going from Las Vegas to Moab Utah specifically to see Arches, you need a reservation. You can't just roll up at 10:00 AM and get in. They will turn you around. Book months in advance or try your luck with the "day before" releases at 7:00 PM MDT on Recreation.gov.
- The Wind. The desert can get incredibly windy. If you’re driving a high-profile vehicle like a Sprinter van or a Jeep with a rooftop tent, be ready to white-knuckle the steering wheel near Green River.
- Cell Service. It’s spotty. Download your maps for offline use. If you break down on a side road like Hole-in-the-Rock or near the San Rafael Swell, you won't have bars.
The Moab Reality Check
When you finally pull into Moab, it feels like a mountain town that got lost in the desert. It’s full of $100,000 custom Jeeps and people covered in red dust.
Everything is expensive. A burger is going to cost you twenty bucks. A gallon of gas is usually 50 cents higher than in Vegas or Salt Lake. That’s the "remote tax."
If you’re looking for a place to stay, the hotels on the north end of town are closer to Arches, but the ones downtown let you walk to the breweries and shops. Personally? I’d camp. But even the campsites fill up. If you’re looking for "dispersed" (free) camping, you have to go further out toward Willow Springs or south toward Monticello. The Bureau of Land Management (BLM) has strictly cracked down on where you can pitch a tent because, frankly, people were trashing the place. Follow the signs. Pack out your poop. Literally.
Actionable Next Steps for Your Trip
Stop planning and start doing the logistics that actually matter.
- Check the UDOT Traffic Website: Specifically look at the I-15 Virgin River Gorge and the US-6 Soldier Summit reports.
- Book Your Arches Entry: If you don’t have a permit, plan to enter the park before 7:00 AM or after 4:00 PM (check current seasonal rules as these windows shift).
- Download Offline Maps: Open Google Maps, search for the area between Vegas and Moab, and download the entire square.
- Hydration Prep: Buy a 5-gallon reusable water jug at a grocery store in Vegas before you leave. It’s cheaper and better for the environment than thirty small plastic bottles.
- Vehicle Check: Check your coolant levels and tire pressure. The heat on the drive from Las Vegas to Moab Utah will find the weakness in your cooling system and exploit it.
The drive is long, it’s hot, and it can be boring if you stay on the interstate. But when you see that first glimpse of the Colorado River cutting through the red sandstone, you’ll realize why people obsess over this corner of the world. Just keep your eyes on the road and your radiator full.
