This is the one route in America where flying isn’t the obvious answer. A Southwest flight from Burbank to Oakland costs $49–89 and takes 1.5 hours gate-to-gate. Driving I-5 costs about $55–70 in gas and takes 5.5 hours — but you have a car when you arrive. The Pacific Coast Highway turns it into one of the greatest road trips on earth. And Amtrak’s Coast Starlight is one of the most scenic train rides in North America, hugging cliffs and beaches you can’t see from any road. We broke down the real, door-to-door cost of all five ways to get from LA to San Francisco — because the “cheapest” option depends entirely on why you’re going.

Option 1: Fly ($49–200, 1.5 Hours)
The fastest option by a mile. LA to SF is one of the most competitive domestic routes in the country — eight airlines operate it across five airports. The trick is knowing which airport pair to use.
| Airline | Fare Range (OW) | Route | Key Perk |
|---|---|---|---|
| Southwest | $49–89 | BUR → OAK/SJC | 2 free bags, no change fees |
| JetBlue | $59–120 | LGB → SFO | Free WiFi, snacks, legroom |
| Alaska | $69–130 | LAX/BUR → SFO | Good loyalty program for West Coast |
| United | $79–150 | LAX → SFO (hub) | Most frequent, best SFO transit |
| Delta | $79–150 | LAX → SFO | SkyMiles, Comfort+ upgrade avail. |
| American | $79–150 | LAX → SFO | Oneworld miles |
| Spirit | $39–70 base | LAX → SFO/OAK | Cheapest base fare (bags extra) |
| Frontier | $39–70 base | LAX → SFO/OAK | Flash sales, bags extra |

The locals’ airport hack
Burbank (BUR) → Oakland (OAK) on Southwest is the move Californians know about. BUR is tiny — you can arrive 45 minutes before departure and breeze through TSA. OAK is smaller and less chaotic than SFO. BART from OAK to downtown San Francisco takes 25 minutes for $11. Compare that to SFO, where BART costs $10 and takes 30 minutes. The time you save at smaller airports often cancels out any fare difference. Southwest doesn’t show up on Google Flights or Kayak, so search southwest.com directly.
Hidden costs of flying
That $49 fare is not $49 door-to-door. Uber/Lyft to the airport: $25–50 each end. Airport parking at BUR: $12–18/day. Checked bag on Spirit/Frontier: $35–50 each way. Once you add transit on both sides, the real door-to-door cost is $120–250 per person. For a couple, driving starts looking very competitive.

Option 2: Drive I-5 ($55–70 Gas, 5.5 Hours)
The practical drive. Interstate 5 is a straight shot through California’s Central Valley — flat farmland, cattle ranches, and the occasional In-N-Out stop. It’s boring. It’s also the fastest driving route by 2–3 hours.
You have a car in SF — useful for Muir Woods (30 min north), Napa Valley (1 hr north), Half Moon Bay, or a Monterey day trip.
No tolls on I-5. Gas costs roughly $55–70 at California’s ~$4.80/gallon average (March 2026, per AAA), depending on your car’s MPG.
For 2+ people, driving is cheaper than flying. A couple flying Southwest: $100–178 + $50–100 in Uber/BART. Driving: $55–70 gas total.
Parking in SF is brutal. Garage parking runs $30–50/day in downtown/SoMa. Street parking is metered, time-limited, and aggressively ticketed. Hotel parking adds $40–65/night.
Golden Gate Bridge toll: $8.80 (electronic only, no cash). Bay Bridge toll: $7 westbound. These add up on a round trip.
Total real cost for a weekend: $55–70 gas + $60–100 parking (2 days) + $16 bridge tolls = $130–190. For a solo traveler, flying is faster and roughly the same price. For a couple or family, driving wins on cost.

Option 3: Pacific Coast Highway ($350–570 for 2 Days, Priceless Scenery)
This isn’t a commute — it’s a trip. Highway 1 from LA to SF is regularly ranked among the world’s greatest drives, and it earns it. We’d recommend splitting it over 2 days with an overnight in Big Sur or Cambria. Trying to do it in one day means rushing through the best parts.
The Best Stops (North to South)
Santa Barbara (2 hours from LA) — wine tasting in the Funk Zone, Stearns Wharf, excellent lunch stop. Pismo Beach (3.5 hrs) — clam chowder at Splash Café ($9.50 for a bread bowl, cash only). San Simeon (4.5 hrs) — Hearst Castle tours ($25–47), elephant seal rookery (free, incredible). Big Sur (5.5 hrs) — Bixby Bridge, Pfeiffer Beach ($12 parking), McWay Falls (0.3-mile walk, free). Carmel-by-the-Sea (7 hrs) — charming village, no street addresses (seriously). Monterey (7.5 hrs) — Cannery Row, Monterey Bay Aquarium ($55 adult). Half Moon Bay (9 hrs) — last stretch before SF.
| Expense | Cost |
|---|---|
| Gas (470 miles at ~$4.80/gal, 30 MPG) | $55–75 |
| Hotel in Big Sur or Cambria (1 night) | $180–400 |
| Food (2 days of road trip meals) | $60–120 |
| Activities (Hearst Castle, Aquarium, etc.) | $25–100 |
| Total for 2-day PCH trip | $320–695 |
Timing matters
April through October is prime PCH season — clear skies, wildflowers in spring, warm evenings. November through March means possible road closures in Big Sur due to mudslides (check Caltrans road conditions before you go). Weekdays are dramatically less crowded than weekends. The Big Sur stretch is one lane in each direction — a slow RV in front of you can add an hour. Be patient. It’s worth it.
Option 4: Amtrak Coast Starlight ($40–80, 10–12 Hours)
The scenic underdog. Amtrak’s Coast Starlight runs daily from LA Union Station to Emeryville (across the bay from SF), where a free bus shuttle takes you into the city. Parts of the route — especially between San Luis Obispo and Salinas — run along coastal cliffs and beaches you literally cannot see from any road. The observation car has floor-to-ceiling windows and is one of the best-kept secrets in American rail travel.
Coach: $40–80. Roomette (tiny private sleeper): $150–250. Book 2–4 weeks out for the best prices.
Free to roam. Walk to the observation car, bring your own food and drinks (including alcohol), work on your laptop with intermittent WiFi, stretch your legs whenever you want.
No security lines, no airport commute. Union Station in downtown LA is gorgeous and accessible by Metro. Show up 30 minutes before departure.
It’s slow. Really slow. Scheduled at 10–12 hours, but delays of 1–3 hours are common. Amtrak shares track with freight trains, and freight always has priority.
You arrive in Emeryville, not SF. The shuttle bus adds 30–45 minutes to reach downtown San Francisco.
Honestly? We love this train. It’s not for anyone in a hurry, but if you enjoy the journey, can work remotely during the ride, or just want a day of staring at the Pacific with a book and a beer — the Coast Starlight is a genuinely special way to travel. The morning departure from LA means you see the coastline in daylight.
Option 5: Bus ($20–40, 6–7 Hours)
Nobody romanticizes the bus, but it’s the cheapest option by a wide margin. FlixBus runs multiple daily departures from LA to SF for $20–40 with free WiFi and power outlets. Greyhound is similar pricing. The ride takes 6–7 hours via I-5 — roughly the same as driving but without the gas bill or parking headache. Best for students and budget travelers who want to save every dollar. It works, it’s fine, it’s just not exciting.

Our take
Quick weekend trip? Fly Southwest BUR→OAK, BART into the city. Need a car for Napa/Muir Woods? Drive I-5 up, PCH back (or vice versa). First time doing LA to SF? Drive the PCH over 2 days — you’ll never forget it. Want something different? Amtrak Coast Starlight with a book and a window seat. Broke college student? FlixBus, no shame. The beauty of this route is that every option has a genuinely good reason to exist.
Quick San Francisco Tips
Getting Around — Don’t Rent a Car IN the City
SF is a Muni + BART city. Muni covers buses, streetcars, and cable cars within SF ($2.50 per ride, $5 for cable cars). BART connects to the East Bay and airports. Uber and Lyft are everywhere. Do not rent a car just for San Francisco — parking is $30–50/day, the hills will destroy your clutch (and your nerves), and everything worth seeing is accessible by transit or walking. Only get a car if you’re leaving the city for Muir Woods, Napa, or the coast.
The Weather Warning Nobody Gives You
San Francisco summer is NOT Los Angeles summer. The average high in July is 67°F. Morning fog burns off by noon (maybe), then rolls back in by 5pm. The Mark Twain quote “The coldest winter I ever spent was a summer in San Francisco” is apocryphal but accurate. Bring layers. A hoodie or light jacket is mandatory year-round. September and October (“Indian summer”) are actually the warmest months, regularly hitting 75–80°F.
Things to Do
Alcatraz ($42.65 adult — sells out 2–4 weeks ahead, book early or you won’t go), Golden Gate Bridge bike ride ($35–55 rental, ride across + ferry back from Sausalito), Fisherman’s Wharf (touristy but the clam chowder bread bowls at Boudin are legit, $13), Mission District (best burritos in America, $12–16 at La Taqueria or El Farolito), Chinatown (oldest in North America, dim sum at Good Mong Kok for $4–6 per plate).
Frequently Asked Questions
What’s the cheapest way to get from LA to San Francisco?
FlixBus at $20–40 is the absolute cheapest for a solo traveler. If you want to fly, Southwest from Burbank to Oakland starts at $49 one-way. For two or more people, driving I-5 is cheapest at $55–70 total in gas (no tolls). Amtrak coach starts at $40 but takes 10–12 hours. The “cheapest” answer depends on how many people are traveling and how you value your time.
Is it worth driving the Pacific Coast Highway from LA to SF?
Absolutely — but do it as a 2-day trip, not a rush job. The Big Sur stretch of Highway 1 is one of the most scenic drives in the world. Key stops: Santa Barbara (wine tasting), San Simeon (Hearst Castle, elephant seals), Big Sur (Bixby Bridge, Pfeiffer Beach), Carmel-by-the-Sea, and Monterey. Budget $320–695 for gas, one night’s hotel, food, and activities. Best season: April through October. Do it at least once — it’s a bucket-list drive for a reason.
How long is the drive from LA to SF?
Via I-5 (the fast, boring route): 5.5–6 hours depending on traffic, about 380 miles. Via the Pacific Coast Highway (scenic route): 8–10 hours of actual driving, 470 miles, but realistically a 2-day trip with stops. The US 101 split (mix of highway and coast) takes about 6.5–7 hours. Avoid leaving LA between 3–7pm on a Friday — the I-5 on-ramp from the 405 can add an hour.
Is Amtrak Coast Starlight worth it?
If you have the time, yes. The coastal scenery between San Luis Obispo and Salinas is stunning — cliffs, beaches, and stretches of coastline you can’t see from any road. The observation car with panoramic windows is the highlight. At $40–80 for coach, it’s cheaper than flying. The downsides: it takes 10–12 hours (often delayed 1–3 hours), and you arrive in Emeryville, not San Francisco (free bus shuttle adds 30–45 minutes). Best for people who enjoy the journey itself.
Which airport is better — SFO or Oakland?
SFO is the bigger airport with more airline options and a direct BART connection to downtown SF (30 minutes, $10). Oakland (OAK) is smaller, less crowded, and often has cheaper fares — BART to downtown SF takes 25 minutes for $11. If you’re flying Southwest (which doesn’t serve SFO from Burbank), Oakland is the move. For United or most legacy carriers, SFO has more frequency. San Jose (SJC) is also an option but farther from the city (1 hour by Caltrain + BART).
