You're standing on the Strip, the sun is starting to dip behind the mountains, and you realize you've got to get back to the coast. It’s a classic trek. But when people ask about the distance from las vegas to los angeles how many miles it really is, the answer usually depends on whether you're looking at a map or sitting in a gridlock behind a semi-truck in Primm.
The straight-shot distance is one thing. The reality of the I-15 is another beast entirely.
If you go by the numbers provided by the Nevada Department of Transportation (NDOT), the driving distance from the heart of Las Vegas to downtown Los Angeles is roughly 270 miles. That’s the baseline. If you’re flying, the "as the crow flies" distance is shorter—about 230 miles—but unless you’ve got wings or a private jet at Henderson Executive Airport, that number doesn't help you much.
Most people assume it’s a four-hour drive. It rarely is.
Breaking Down the Numbers: Las Vegas to Los Angeles How Many Miles?
Let's get specific because "about 270" is for amateurs. If you are leaving from the Bellagio and heading to Santa Monica Pier, you're looking at closer to 285 miles. If you’re just hitting the outskirts of San Bernardino, you might only clock 230 miles.
The route is almost exclusively the Interstate 15 South. It’s a ribbon of asphalt that cuts through the Mojave Desert, passes the World’s Tallest Thermometer in Baker, and climbs over the grueling Cajon Pass.
Why does the mileage matter? Because of the "Baker Grade."
Between the Nevada border and the town of Baker, there’s a long, sustained incline. If you’re driving an older car or hauling a trailer, those 270 miles feel like 500. It’s a graveyard for overheated engines. According to Caltrans, the I-15 corridor handles upwards of 45,000 vehicles a day on average, and that number spikes during 3-day weekends like Memorial Day or Labor Day.

On those days? The mileage is irrelevant. You aren't measuring the trip in miles; you're measuring it in podcasts. A 270-mile trip can easily turn into an eight-hour ordeal.
The Pit Stops That Add Up
You probably won't drive those miles in a vacuum. Most travelers stop. Every stop adds a bit of "drift" to your odometer.
- Seven Magic Mountains: Just 10 miles south of the Strip. It’s a quick photo op, but the turnoff adds a mile or two.
- Primm/State Line: About 40 miles into your journey. It’s the last chance for cheap Nevada gas, though "cheap" is relative these days.
- Barstow: This is the halfway point. Specifically, the Barstow Station—a collection of train cars converted into a food court. It’s roughly 150 miles from Vegas. If you've made it here in two hours, you're speeding.
- Victorville: The 200-mile mark. This is where the desert ends and the "Greater Los Angeles" sprawl begins. From here, the mileage becomes a psychological battle against traffic.
Beyond the I-15: Alternative Routes and Their Mileage
Sometimes the 15 is a parking lot. It happens. A truck flips near Zzyzx Road, and suddenly you're looking for a workaround.
You could take the "back way" through the Mojave National Preserve. You’d take the I-15 to Nipton Road, then cut through Kelso and come out near Amboy on Route 66. This route is stunning. It’s haunting. It’s also significantly longer—probably adding 30 to 40 miles to your total—and there is zero cell service for long stretches. If you break down there, you're in a Cormac McCarthy novel.
Another option is heading south toward Searchlight, Nevada, and picking up the I-40 West toward Barstow. This adds about 20 miles but can save you time if the I-15 is backed up at the California agriculture inspection station.
That inspection station is a notorious bottleneck. Even though it’s only a few miles past the border, the "mileage" spent idling in line can burn more fuel than 50 miles of open highway driving.
The Electric Vehicle Factor
If you're driving a Tesla or a Lucid, the question of las vegas to los angeles how many miles is actually a question of "how many kilowatt-hours."

A standard Tesla Model 3 Long Range has a capacity that comfortably covers the 270 miles on paper. But the Mojave is a thief. High temperatures (often over 110°F) force the AC to work overtime, while the elevation gain from the desert floor up to the Cajon Pass (about 3,777 feet) drains the battery significantly faster than flat-ground driving.
Smart EV drivers usually stop at the Superchargers in Baker or Barstow. You’re essentially trading 20 minutes of your time for the peace of mind that those last 100 miles into the LA basin won't end on the back of a flatbed.
What Most People Get Wrong About the Drive
The biggest misconception? That the drive is "flat."
It’s a mountain climb. You start at an elevation of about 2,000 feet in Vegas, drop down to nearly 900 feet in Baker (the low point), then climb up to nearly 4,000 feet at the pass before dropping back down to sea level in LA.
This constant shifting in elevation affects your gas mileage. You might get 35 mpg on the downhill stretches and 18 mpg on the climbs. If you’re tracking your "miles to empty" gauge, don't trust it when you’re climbing out of the Baker Sink. It will lie to you.
Also, people forget about the wind. The Cajon Pass and the stretch between Barstow and Victorville are notorious for high crosswinds. If you're in a high-profile vehicle like an SUV or a van, you’ll be fighting the steering wheel. It’s physically tiring in a way a standard highway drive isn't.
Factoring in the Los Angeles "Finish Line"
Where you end up in LA changes everything. Los Angeles isn't a city; it's a collection of suburbs looking for a center.

- To Pasadena: 260 miles.
- To Downtown LA: 270 miles.
- To Santa Monica: 285 miles.
- To Anaheim (Disneyland): 265 miles.
The final 20 miles into the city can take as long as the first 100 miles in the desert. If you hit the 210 or the 10 freeway at 4:00 PM on a Tuesday, those last few miles are a crawl.
Real-World Travel Tips
If you're planning this trip, don't just look at the odometer. Look at the clock.
The best time to drive is Tuesday or Wednesday morning. You’ll hit the 270 miles in about 4 hours and 15 minutes. The worst time? Sunday afternoon. Sunday is the "Great Migration." Everyone who went to Vegas for the weekend is heading back to Cali. I have seen that 270-mile trip take 9 hours.
Check the "I-15 Exit 286" cameras online before you leave. This is the Primm area. If you see a sea of red brake lights there, stay in Vegas for another buffet. It isn't worth it.
Also, keep your tank above a quarter. There are stretches—long ones—where there isn't a single gas station. Between Baker and Barstow, it’s mostly just sand and scrub brush. If you run out of gas at mile 180, you’re in for a very expensive tow.
Actionable Steps for Your Journey
- Check your tire pressure: The heat of the Mojave causes air to expand. If your tires are already over-inflated, you risk a blowout on the I-15.
- Download offline maps: Google Maps is great, but there are dead zones near the Halloran Summit. Download the "Las Vegas to LA" area for offline use.
- Time your departure: Leave Vegas before 9:00 AM or after 7:00 PM if you're traveling on a Sunday.
- Watch the Cajon Pass: Use an app like Waze to see if there are accidents on the descent into San Bernardino. It’s the most common spot for pile-ups due to the steep grade and high speeds.
- Gas up in Nevada: Generally, gas is 50 cents to a dollar cheaper per gallon in Las Vegas or Jean than it is once you cross the line into California.
The trek from Las Vegas to Los Angeles is a rite of passage for West Coast travelers. It’s a 270-mile stretch of neon, Joshua trees, and heat haze. Respect the distance, watch your gauges, and always keep a gallon of water in the trunk. The desert doesn't care about your schedule.
