Road trip from Portland to San Diego

Updated by Dianne Titos on March 1 2024

Oregon and California hold some of America's most scenic coastlines and some of its most spectacular mountain ranges. A road trip from Portland to San Diego will take you across mountain ranges, through lush valleys, and on the adventure of a lifetime.

The 1,350-mile road trip from Portland to San Diego takes 27 hours of driving along the coast. Attractions include Big Sur, Los Angeles, and San Francisco, as well as Yosemite National Park and Sequoia National Forest if you travel inland.

Planning a road trip of this scale is challenging, so read on to find out what the best routes are, things to do along the way and where to stay.

How far is San Diego from Portland and how long will the Road Trip Take?

Coastal Route1,350 miles27 hours
Inland Route1,200 miles21 hours 45 minutes

The road trip from Portland to San Diego covers 1,350 miles along the coast and will take you at least 3 days of driving when breaks are factored in. I would recommend taking at least a week, if not more, to enjoy this epic road trip.

Never straying from the Pacific Coast, this route will take you through the American West's finest cities, such as Malibu and San Francisco, among others.

On the other hand, the inland route will take you through rugged mountains and give you an opportunity to explore some of America's best national parks. Both routes will take you through the bustling metropolis of Los Angeles before you reach San Diego.

The advantage of taking this route is that it cuts your travel time by about 5 hours, although you can easily detour to a number of scenic attractions at the California/Nevada border.

The major cities along the route may bring some congestion issues, so you could stay on the outskirts and use public transport to explore the downtown areas. If you have the time, though, driving through the cities can be just as enjoyable.

Best road trip route from Portland to San Diego

The best road trip route from Portland to San Diego depends what type of scenery you like. If you prefer bays and beaches, the coastal route is best. If you prefer mountains and forests, then the inland route might be a better option.

If you want to get the best of both worlds, your best move would be to take one on the way to San Diego and the other on the return trip.

Whether you're flying into Portland or you simply don't have your own transport in the city, renting a car for your road trip is something you'll want to take care of ASAP.

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

You can go on a road trip from Portland to San Diego at any time of year. Summer will be the busiest time of year in every place along the route, because the weather is more pleasant.

Winter will be much quieter in the national parks along the routes. Most stay open all year round but often experience lots of snow. Therefore, you may need special equipment like tire chains.

The weather on the coastal route will be mild but probably wet in winter. The weather can be very varied at every time of year along the west coast. Winter will also be the quietest season along the coast, but this means there will be some great deals on accommodation.

Generally, hotels will be cheapest in these places in winter with prices rising in summer. The shoulder seasons, fall and spring, can be a great time to travel as it represents a balance of good weather and reasonable prices.
