Road Trip From San Diego To Phoenix

By Sasha Yanshin | Updated on 14 March 2023

Driving from San Diego to Phoenix will take you on a unique drive across Southwest United States passing through forests, mountains, major cities, and seemingly endless deserts.

You could certainly fly from San Diego to Phoenix, but if you're looking for a journey where you'll see it all, this is the road trip for you.

The 355-mile drive will take you around 5 hours and 30 minutes. It's feasible to do it in one go, but taking the more scenic route and splitting it into 2 or 3 days will allow you to appreciate the parks, forests, and cities you're going by anyway.

If this sounds like a journey you want to take, here is everything you need to know, and some places and sights you don't want to miss.

How far is Phoenix from San Diego and how long will the road trip take?

All things considered, the drive from San Diego to Phoenix isn't a particularly long one, the shortest route being 355 miles. This route will take you around 5 hours and 30 minutes following the I-8.

RouteDistanceDriving Time

Scenic Route
(via I-10)
420 miles6 hours 30 minutes

This is without accounting for any pit stops you might need to make, so you'll need to tack on an hour or two for those.

Also keep in mind that depending on when you leave San Diego, you might experience some traffic delays.

Heading out during rush hour will slow you down considerably, as will leaving on a Friday or Saturday and contending with other drivers leaving for the weekend.

If, however, you'd like to take the much more scenic 420-mile route, you'll only need to add an extra hour to your route.

You could still do this route in a day, but you'd be missing out on so many of the amazing sights you're going to be passing.

And anyway, what's the point of taking the scenic route if you don't stop to look at all the scenery?

Best road trip Route from San Diego to Phoenix

The fastest way to get from San Diego to Phoenix is by the I-8, which will take you right along the US/Mexico border. By taking this route, you'd still have the opportunity to stop at some state parks, like the Cuyamaca Rancho State Park.

The longer route, however, gives you many more opportunities for experiencing both city life and sightseeing. This one will take you north towards Los Angeles on the I-15, past several parks and forests before heading east through the desert towards Phoenix.

Take exit 115 onto AZ- 85 until you reach the I-10. Hang a right and follow the I-10 the rest of the way into Phoenix.

Best places to stop between San Diego and Phoenix

If you're looking to break up the long drive and relax on your road trip, here are a couple of great options for spending the night on you way.

Explore Temecula

If you're a wine connoisseur, you're going to love Temecula. This city is a popular destination for tourists and is also well-known for its nearby vineyards.

Book your room at the Ponte Vineyard Inn, where you'll enjoy the hotel's peaceful and picturesque environment.

The on-site restaurant features outdoor dining so you can enjoy the weather while you eat. The inn is surrounded by gorgeous vineyards and it's only a 10-minute drive away from the Temecula Creek Inn Golf Course.

While you're in Temecula, you should take some time to explore Old Town Temecula, and visit one of the city's spas for some pampering.

You can also sign up for one of the many wine tours, and visit several wineries in the area like the Wilson Creek Winery.

If you feel like going around in style, why not take one of these wine tours in a horse-drawn carriage offered by the Temecula Carriage Company?

Relax in Palm Springs

This popular resort destination in the Sonoran Desert is the perfect place to get a little R&R before making the rest of the trek towards Phoenix.

The stunning L'Horizon Resort & Spa is a perfect place to relax in Palm Springs - you'll spend the day pampering yourself at the spa and lounging by the pool before enjoying an intimate meal at the restaurant. The rooms here are really amazing - check them out!

While you're in Palm Springs, visit the Palm Springs Art and Air Museums to learn more about the city's history and culture.

If you decide to take this road trip in April, you'll also get the chance to check out the nearby Coachella Valley for the Coachella Valley Music and Arts Festival.

There are plenty of other tourist attractions in the city, and Palm Springs is very close to Mount San Jacinto, which you'll be able to visit via the Palm Springs Aerial Tramway.

Best time to go on a road trip from San Diego to Phoenix

Since a good chunk of your drive will be through the desert, you should know that southern California and Arizona summers tend to be very hot and dry.

Temperatures in Phoenix can very quickly reach well above 100 °F during the summer months. You can certainly take this trip in the summer (I've done the reverse of this drive in August once), but you'll want to make sure you're staying hydrated and bring plenty of water with you.

Another thing to consider about Phoenix in the summer is that many of the city's attractions will keep you outdoors - exploring the Sonoran desert, visiting the city's botanical gardens, and visiting Papago Park will keep you outside in the heat so be mindful of that.

If you're looking for some milder weather, heading out to Phoenix between November and April will be your best bet. The desert flowers bloom in spring and the weather is mild making it a lot nicer to hike and explore the outdoors. Plus, if you go in April you might get the chance to check out the Coachella Music and Arts Festival before you reach Phoenix.

Keep in mind, though, that the weather during the spring can be somewhat unpredictable. Even though you're driving through the desert, you can get caught in a rainstorm and the temperatures can fluctuate a lot.

Winters in Phoenix will bring you temperatures around the mid 60s, far more comfortable than summer temperatures. Be aware, however, that winter is peak tourist season in Phoenix. While the rest of the United States experiences rainfall, snow and chilly weather, snowbirds will be heading down to Phoenix to enjoy the warmth.

Just to remind you again, no matter what time of year you decide to go, make sure that you bring a lot of water and that your car's air conditioning is working well. San Diego may have perfect temperate weather all year round but the Sonoran desert can get mighty hot.
