Road trip route from San Diego to Yellowstone National Park
Hop on the I-15 North straight out of San Diego, switching to the I-215 at Murrieta. You can stop at San Bernardino National Forest if you want to stretch your legs under the shade of the trees before heading out into the desert.
The I-215 merges with the I-15 after a few more miles. The route from here is very simple, passing Mojave National Preserve before crossing into Nevada to reach the vibrant streets of Las Vegas for your first recommended overnight stop.
After you've finished trying your luck in Vegas, get back on to the I-15 heading north. From Littlefield the road takes you through the Virgin River Gorge, following the path carved out by the river for several miles.
After crossing into Utah you'll approach Zion National Park, which is another great spot to break your journey. Take Exit 16 of the I-15 to get up to the park.
Continue on the I-15 northwards towards Salt Lake City. You have the option to detour to Dixie National Forest before you reach the city - a highly recommended stop if you're keen on hiking, with some very photogenic rocky landscapes to explore.
Stick with the I-15 as you leave Salt Lake City, which takes you across yet another state line into Wyoming. Take a break at Idaho Falls before finally leaving the Interstate at exit 119 and continuing along Highway 20 which takes you right up to Yellowstone National Park.
Optional detour to the Grand Canyon
From Las Vegas you have the option of extending your trip to visit the Grand Canyon. This will add around seven hours to your drive but is well worth the detour if you still have to check this magnificent natural monument off your bucket list.
Leave Las Vegas on the I-515 and switch to the I-11 at Henderson. You'll cross into Arizona right by the Hoover Dam, and the road changes to Highway 93 here.
Join the I-40 at Kingman, then turn north onto Highway 64 at Williams. This will take you right up to the canyon.
When you've finished exploring and admiring the stunning views, continue east on Highway 64 until it joins Highway 89 at Cameron. This road will take you through many miles of desert landscape, passing Vermilion Cliffs National Monument.
To visit Zion National Park hop onto Highway 9 before returning to Highway 89.
Bryce Canyon, accessed via Highway 12, is your last stop before rejoining the main route on the I-15. To get back to the main route, turn onto Highway 20 at Bear Valley and follow it until you meet the I-15 and continue on your journey north.
Best places to stop between San Diego and Yellowstone National Park
As mentioned above, we would recommend three overnight stops along this beautiful route. We've outlined the best locations below, as well as things to do and places to stay.
You can also combine the stopovers with other activities and sights along the route, depending on how much time you have to take this trip.
Soak up the bright lights of Las Vegas, Nevada
Las Vegas is most certainly one of a kind - it has everything you can want, and more.
Whether it's dining in all you can eat buffets, getting your adrenaline fix on the skyscraper thrill rides or gambling the night away in Caesar's Palace. You'll be sure to never find a dull moment in the entertainment capital of the world.
Around a five hour drive from San Diego, there's more to keep you busy in Las Vegas than you might think. Test your nerves on the thrill rides at the top of the Stratosphere, practice your shooting at the Gun Range, zipline through Fremont Street or indulge yourself at the Heart Attack Grill. The list of optional activities is endless.
There are so many great hotel options to choose from in Las Vegas, but our recommendation would have to be a stay at the stunning Bellagio where there truly is no expense spared. This lavish resort features five swimming pools and its own botanical gardens.
Once you roll up to the on-site parking you'll find yourself right in the middle of this fantastic city. There's so much to do even within the resort that you might not need to leave, but you're in walking distance of many of Vegas's other attractions if you do decide to strike out.
Then, with its incredibly comfortable rooms, wellness spa and 18 on-site restaurants, you'll definitely get some well deserved rest after a long day on the road and an evening exploring the Las Vegas Strip.
Stay overnight in Zion National Park, Utah
Heading further North and situated a pleasant 2 hours and 35 minute drive from Las Vegas you will arrive at your second overnight stop at the magnificent Zion National Park.
This also makes a great stopover if you add on the Grand Canyon detour, you'll just have a longer drive to get all the way here.
As you approach Zion you will be greeted by exceptional views in every direction. Sheer rock faces and vast valleys are scattered throughout the entire National Park.
Zion National Park is a perfect spot for hikers and photographers alike. A true highlight is the five mile round trip hike to Angel's Landing - the elevation gain of 1500ft is challenging, but you'll be rewarded with utterly breath-taking views of the 270 million-year-old rock layers when you reach the top.
Another great activity in Zion is to explore The Narrows as you wade through the Virgin River surrounded by huge 1000 feet tall rock faces.
Hotels are slightly less common in this area, however we have an absolute gem of a recommendation in the SpringHill Suites by Marriott Springdale Zion National Park - a property that oozes both class and modern comfort. Built to make the most of its stunning situation, it's in a perfect location to head out and explore Zion.
Whether you're hiking in the national park or just appreciating the views on a scenic drive, where better to end a day on this road trip than by the on-side pool with its fantastic red rock view.
Explore the Great Salt Lake and Bonneville Salt Flats near Salt Lake City, Utah
Salt Lake City is an amazing spot to stay overnight on your road trip from San Diego to Yellowstone National Park. Situated directly next to the Great Salt Lake and Bonneville Salt Flats, you will be spoilt for choice with the multiple options of excursions and activities available.
Salt Lake City is approximately a 4 hours and 20 minute drive from Zion National Park and a steady 4 hours and 30 minute drive from your final destination of Yellowstone National Park.
There is a wealth of hotel options in Salt Lake City, but our favourite has to be the stylish Radisson Hotel Downtown Salt Lake City. The rooms are exquisitely furnished and the property is superbly located in the centre of the city, a short and easy hop off the Interstate, with ample car parking available.
The Utah Museum of Contemporary Art and the Clark Planetarium are both just a short walk from the hotel. If that inspires you to look to the skies you can even take a short evening drive out of the city to East Canyon State Park for some stunning views of the Milky Way .

Best time to go on a road trip from San Diego to Yellowstone National Park
The route between San Diego and Yellowstone National Park is astonishing all year round, but we would recommend the spring or fall as the best times to take this trip.
There's potential in the winter months for roads and trails through the national parks to be completely closed due to snowfall or unsafe conditions. Or for contrast, if you visit in summer you'll have to factor in some stretches of hot desert driving that won't suit every traveler.
April to May is when Yellowstone really starts to spring back to life after the long, hard winter. Wolves are commonly spotted, bears are starting to emerge from hibernation, and newborn bison can often be seen.
Even if you don't manage to spy any of the park's wildlife, you'll be in for a treat with a burst of colour from the wildflowers. You'll avoid some of the crowds of tourists that can descend on Yellowstone during the summer school holidays too.
That said, a lot of the accommodation in Yellowstone closes for the winter, so check reopening dates if you're planning on visiting in April.
Whether snow covered or dazzled by sunshine, Yellowstone will always supply an abundance of breath-taking views, but vehicle access is very limited when snow is on the ground. The only way to reach Old Faithful at this time of year is via guided snowmobile tour.
One thing's for sure, your road trip from San Diego to Yellowstone National Park will be jam-packed with activities and definitely one you will never forget.
