Planning a road trip in San Diego is more than just "checking out attractions." The practical issues you'll encounter on a road trip—how to drive from Los Angeles, how to park in the city, whether to cross the border to Tijuana, Mexico—are often the key to a smooth journey. As a local car rental company with years of experience in California, we've compiled this article into practical road trip experience, offering a direct perspective from a driver's point of view to help you plan your route, attractions, parking, and vehicle type all at once.
Highlight the finishing touches:
Let me first answer three of the most frequently asked questions.
- How long does it take to drive from Los Angeles to San Diego? The entire journey on I-5 is about 120 miles, and under normal traffic conditions it takes about 2–3 hours; however, if you encounter peak hours on Friday afternoons or Sunday evenings, it is not uncommon for traffic to exceed 4 hours.
- How many days is it worth spending in San Diego? Two days are enough to see the highlights of the city (Balboa Park and the harbor area); three days are ideal if you want to add the La Jolla coastline; and five days would be more relaxed if you also want to visit the Julian mountain town or cross the border into Mexico.
- Do you need to rent an SUV? Not necessarily. A small sedan is sufficient for city driving, unless you plan to hike in the Anza-Borrego desert or cross the border into Mexico, in which case an SUV or a vehicle with higher ground clearance would provide more peace of mind.
Why is a road trip in San Diego worthwhile?
San Diego, California's second-largest city, boasts a Mediterranean climate that makes it suitable for road trips almost year-round, with no worries about snow or road closures in winter. Geographically, it borders Mexico to the south, is only a 2-hour drive north of Los Angeles, and a mere 5-hour drive northeast of Las Vegas, making it an ideal destination for road trips.Los Angeles to Las VegasIn addition to the itinerary, it forms a more complete road trip along the American West.
Compared to the congested pace of Los Angeles, driving in San Diego is significantly easier; compared to the foggy weather of San Francisco, the sunshine here is more consistent. With its moderate city size and limited public transportation coverage, the advantages of driving are more pronounced here than in Los Angeles, especially if you want to visit attractions scattered along the coastline like La Jolla and Coronado – without a car, you're practically missing half the experience.

Comparison of the two main routes
I-5 Coastline (Recommended)The route LA → Irvine → Oceanside → Del Mar → San Diego is about 120 miles long and takes about 2 hours under normal driving conditions. It allows you to visit several coastal towns along the way and is the first choice for most self-driving travelers.
I-15 Inland LineThe route is relatively inland and the scenery is somewhat monotonous, but it is a very practical alternative when traffic is congested during peak hours south of Los Angeles, saving a lot of time stuck in traffic.
Worth stopping at along the way
If you don't want to head straight to San Diego, there are actually quite a few attractions along I-5 that you can visit along the way:
- San Juan CapistranoOne of California's oldest monasteries, a good place to stop and explore along the way.
- Oceanside PierOne of the longest wooden piers in the American West, offering expansive ocean views.
- Carlsbad Flower FieldIt blooms from March to May every year and is a seasonal hotspot for taking photos.
- Del Mar Racecourse AreaThe atmosphere is lively during the summer horse racing season.
- La JollaAlternatively, you can schedule it as the first day of your itinerary, as the first stop before entering San Diego.

Traffic and Public Security
San Diego is relatively safe compared to other major California cities. However, areas like the East Village and Barrio Logan tend to be less crowded after nightfall, so it's advisable to avoid going alone. Regardless of where you park, keeping valuables out of the car is a fundamental principle of driving – a point repeatedly emphasized in Los Angeles driving safety advice, and the same applies throughout California.
Refueling and EV charging
San Diego gas prices are generally slightly lower than Los Angeles, but still higher than the national average. It's recommended to use apps like GasBuddy to compare prices. If you're renting an electric car, Tesla Supercharger stations are fairly well-distributed in downtown San Diego and the surrounding areas; planning your charging station locations before a long trip will give you peace of mind.
San Diego Road Trip vs. Public Transportation
If you're still hesitant about renting a car, first think about your travel itinerary:
Car rental availableThe flexibility has been greatly improved, allowing you to connect the best attractions scattered around the area, such as La Jolla, Coronado, and even the mountain town of Julian, all in one go.
No car rentedBasically, you can only get around the city center by walking and taking the light rail. Places like La Jolla and Coronado are inconvenient to get to, and it's easy to miss most of the highlights.

Frequently Asked Questions (FAQ)
How many days does a road trip in San Diego take? Two days are enough to explore the city highlights. If you want to add La Jolla, I suggest three days. If you want to delve deeper into the Julian Peninsula or cross the border into Mexico, five days would be more than enough.
