5 Days: Los Angeles to San Diego

Most visitors default to picking either Los Angeles or San Diego, then treating the other as an afterthought. This five-day route treats them as two connected chapters of the same trip, with a deliberate stop at Laguna Beach in between rather than a rushed pass-through. It runs Santa Monica and Hollywood first, then heads south along Orange County to San Diego — a different direction, and a different balance, from a two-day Orange County and Catalina Island trip or a five-day Pacific Coast Highway road trip that instead runs north toward Santa Barbara.

A rental car is not optional here. It is used on all five days, including inside San Diego itself, since the point of this itinerary is a proper two-city road trip rather than a single flight-in, flight-out base.

Why Los Angeles to San Diego, and not the other way around

Starting in Los Angeles makes sense for most travelers because LAX is the region’s main international gateway, and Santa Monica and Hollywood give an easy, low-effort first 48 hours to absorb jet lag before a longer travel day. San Diego then becomes the calmer back half of the trip, and its own airport is a straightforward exit point if a one-way flight home works better than looping back to LAX.

The drive from Los Angeles to San Diego is commonly cited at around two hours in free-flowing traffic. That figure is a rough order of magnitude, not a promise: this corridor, largely along Interstate 5, is heavily used by both cities’ commuters and by weekend beach traffic, and the same drive can run well past three hours on a Friday afternoon or a Sunday evening. Building this leg into a Wednesday-to-Thursday midweek slot, as this itinerary does, avoids the worst of that.

Day 1: Santa Monica and Venice

Start in Santa Monica, which works well as a first day because it is compact, walkable once parked, and forgiving of a jet-lagged, slow-moving morning. Walk out onto Santa Monica Pier, then head south along the boardwalk into Venice Beach for the canals and the boardwalk’s street performers and muscle beach.

For an afternoon that pairs the coastline with a wider look at the area’s famous addresses, a guided small-group tour taking in Santa Monica Pier and views toward the Hollywood Sign is a practical way to see both without driving yourself on day one. Close the day with dinner near Santa Monica or Main Street, and get to bed early — day two starts with the two attractions everyone underestimates in terms of driving and parking.

A word on the ocean here: it is cold year-round, closer to the Pacific Northwest than to a warm Mediterranean swimming sea, so plan on wading rather than a long swim unless you are used to it.

Day 2: Hollywood and Griffith Park

Head to Hollywood in the morning, before the Boulevard gets crowded. Walk a stretch of Hollywood Boulevard, then continue to Griffith Observatory: the observatory itself and its grounds are free to enter, but parking is the real constraint, especially approaching sunset and on weekends, so arrive with a flexible time buffer. A separate, paid, timed planetarium ticket is required for a show inside — it is not included with general admission.

The Hollywood Sign itself cannot be reached on foot from the road below and has no direct public access point; it is viewed from marked trailheads and overlooks in Griffith Park or from a distance around Hollywood. A guided option removes the guesswork: a small-group SUV day tour is really built for tomorrow’s leg south, but if hiking appeals more than driving today, a dedicated Hollywood Sign hike is worth booking separately through the Hollywood Sign and Griffith guide.

Spend the rest of the afternoon in West Hollywood or Beverly Hills if museums or shopping appeal more than another hike; both sit within a short drive of Griffith Park.

Day 3: South to Laguna Beach

This is the pivot day. Rather than driving straight through to San Diego, break the trip at Laguna Beach in Orange County — worth a full day, not a 30-minute photo stop, since it splits a long single push into two manageable legs and gives real time on a genuinely different kind of coastline from Santa Monica’s.

The drive down from Los Angeles takes roughly an hour to 90 minutes depending on traffic through Orange County, shorter than the LA-San Diego leg but subject to the same rush-hour caveats. Once there, an easy way to get oriented is a walking food tour through Laguna Beach’s galleries and eateries, which covers the town’s compact downtown on foot. Spend the rest of the day on the beach itself, or browsing the art galleries the town is known for.

Overnight in Laguna Beach rather than pushing on to San Diego the same day — it keeps day four’s drive shorter and gives a full evening in a town most Los Angeles-only itineraries skip entirely. For a wider look at the surrounding towns, see the Orange County day-trip guide.

Day 4: On to San Diego

From Laguna Beach, the remaining drive to San Diego is shorter than the full Los Angeles-San Diego run, typically well under two hours off-peak. Even so, treat any stated drive time as an order of magnitude rather than a fixed number: this stretch of Interstate 5 sees the same weekend and rush-hour swings as the rest of the corridor, and there is no version of this route that reliably guarantees a fixed door-to-door time.

Spend the afternoon getting oriented in San Diego — Balboa Park and the Gaslamp Quarter are reasonable first stops — before an evening focused on the harbor. A city tour combining the USS Midway Museum and Old Town San Diego is an efficient way to cover two very different sides of the city, naval history and the area’s Spanish and Mexican-era roots, in a single guided outing without needing to plan the logistics yourself.

This itinerary stays within San Diego itself and does not include a crossing into Tijuana or Mexico. Anyone wanting to add the border should treat that as a distinct, optional extension with its own planning — not an assumed part of these five days.

Day 5: San Diego and departure

Use the final day for whichever side of San Diego appeals most: the zoo and Balboa Park’s museums for a slower, walkable morning, or the beach neighborhoods of Pacific Beach and La Jolla for a coastal close to the trip. Because a rental car has been used throughout, either direction is realistic without needing to plan around bus or trolley schedules.

Depart from San Diego’s own airport if your flight allows it — it is considerably smaller and easier to navigate than LAX, and it avoids driving back north on day five. If a return flight from Los Angeles is unavoidable, budget the same two-hour, traffic-dependent drive back up that framed day four, and again build in slack rather than cutting the return connection close.

All prices exclude California sales tax, which is added at the till and commonly runs in the 9.5%-10.25% range in the Los Angeles and San Diego area, and exclude tipping, which is expected rather than optional at sit-down restaurants and with guides.

Where this itinerary differs from similar routes

It is worth being clear about what this trip is not. It is not the shorter two-day Orange County and Catalina Island itinerary, which stops at the coast and adds an island crossing instead of continuing south to San Diego. It is also not the five-day Pacific Coast Highway road trip, which runs the opposite direction, north from Los Angeles toward Santa Barbara, and covers a very different stretch of coastline. This route’s identity is the south-bound line from Santa Monica through Hollywood, Laguna Beach and down into San Diego, treating the Los Angeles-San Diego drive as a deliberate, two-stage journey rather than a single long push.

For a longer version that adds the desert instead of San Diego, see the seven-day Southern California grand tour; for a shorter first-timer’s introduction to Los Angeles alone before deciding whether to extend south, the two-day first-time Los Angeles itinerary is a useful starting point. Practical planning questions that come up on this route, including parking, timing and where to base yourself, are covered in the Los Angeles planning guide and the how many days in Los Angeles article.

Los Angeles to San Diego road trip: frequently asked questions

How long does the drive from Los Angeles to San Diego actually take?

Roughly two hours in free-flowing traffic, but that figure is an order of magnitude, not a guarantee. Friday afternoons, Sunday evenings and holiday weekends on this corridor can stretch the same drive well past three hours, so it is worth building slack into the schedule rather than booking a tight connection around it.

Do you need a rental car for this itinerary?

Yes, for the whole five days. Santa Monica, Hollywood and Laguna Beach are not realistically linked without one, and the San Diego leg only works as a road trip rather than a day trip if you have your own vehicle once you arrive.

Is Laguna Beach worth a full day, or just a stop?

A full day works well: it breaks the drive south into two manageable legs and gives time for the beach, the art galleries and a proper coastal walk, rather than a rushed 30-minute photo stop between two cities.

Does this itinerary cross into Mexico?

No. This route stays in San Diego and does not include a border crossing into Tijuana. Anyone wanting to add the border should treat it as a separate, optional side trip with its own planning, not an assumed extension of these five days.

Can this itinerary be done without a car using trains or buses?

Not really. There is a rail option between Los Angeles and San Diego, but it does not cover Laguna Beach or the wider stops in this plan, and public transit within San Diego and around Laguna Beach is limited enough that a car remains the practical choice for this specific route.

What’s the best order: Los Angeles first or San Diego first?

Starting in Los Angeles and finishing in San Diego, as laid out here, works best for most travelers flying into LAX, since it avoids backtracking and lets the trip end at a smaller, easier airport if you fly out of San Diego instead.

Is five days enough, or should this be longer?

Five days is enough to get a real feel for both cities without rushing, but it is tight if you also want a theme park day or a Catalina Island crossing — those are better treated as separate itineraries or a longer trip.
