You can make Phoenix to San Diego in about 5.5 hours, but the people who love this drive never do it in one straight shot. At around 355 miles on I-8, it is short enough to start after breakfast and long enough to earn a night somewhere memorable.

Aim to clear Phoenix before the morning rush, or after it, never in it. Fill the tank on the edge of town where prices usually drop, set the playlist, and settle in for the first 183 miles to Yuma.
The headline stop on this route is Imperial Sand Dunes. Leave real time for it; it sets the tone for the whole trip.
Yuma
Yuma sits about 183 miles in. It is the natural place to stop for the night: hotels are plentiful, rates beat the big-city ends of the route, and you wake up with the hardest miles already behind you.
Nearby, Yuma Territorial Prison is worth the short detour if the day is going well.
El Centro, the last stretch
El Centro sits about 247 miles in. It makes a good spot to stretch, eat something that is not from a gas station, and swap drivers.
Rolling into San Diego
The final 108 miles always go faster than you expect. Save a little energy for Climb over the Laguna Mountains; it is a fitting finish.
By the end you will have seen Imperial Sand Dunes, Yuma Territorial Prison and Climb over the Laguna Mountains, and you will understand why this corridor is a classic.
When to go and how to pace it
One night is the sweet spot. Yuma, AZ is where most people stay, so book ahead on summer weekends.
Check live gas prices along I-8 before you go; they can swing a lot from one state or county to the next. XCRSN prices every leg for your exact car.
