San Francisco and Los Angeles are California's two great cities, about 560 kilometres apart by road and linked by everything from America's scenic Coast Starlight train to a handful of short-haul flights. None of the options is perfect for every trip — the train is beautiful but slow, flying is fast but fiddly, and driving the Pacific Coast Highway is the journey of a lifetime if you have the time. Here is what to expect from each.
The scenic way: the Coast Starlight
Amtrak's Coast Starlight is one of the great train journeys in North America. It runs from Los Angeles Union Station to Seattle, and the California leg — roughly 9 to 12 hours from Los Angeles to San Francisco (or Oakland, with an onward bus connection) — hugs the Pacific coast for long stretches, passes through wine country and cuts through the Salinas Valley. It is slow, it frequently runs late, and many passengers would not trade the experience for anything.
The Coast Starlight offers coach class and sleeper accommodation. Coach is a comfortable wide-seat configuration, perfectly usable for a daytime journey; a sleeper gives you a private room, meals included in the price, and a very different atmosphere. A reservation is required for both classes. The train is loved by rail enthusiasts and slow travellers, and genuinely unsuited to anyone with a fixed arrival time in mind — delays of one to three hours are not uncommon.
Note that the train arrives at Emeryville, near Oakland, rather than downtown San Francisco; Amtrak runs a connecting bus across the Bay Bridge to San Francisco's Caltrain/Ferry Building area. Factor in the extra 30–45 minutes, and pre-book the connection along with your ticket.
The Amtrak Pacific Surfliner and bus combination
A popular alternative to the full-length Coast Starlight is the Pacific Surfliner between Los Angeles and San Luis Obispo or Santa Barbara, combined with an Amtrak Thruway coach connecting north to the San Francisco Bay Area. This is usually cheaper and runs more frequently than the Coast Starlight. Journey times vary depending on connections, but plan for the better part of a day. It is a practical option that still shows off stretches of the California coast.
The fastest way: flying
Multiple airlines operate the SFO–LAX route, and it is one of the busiest domestic air corridors in the world. The flight is about 1 hour 20 minutes. However, both San Francisco International and Los Angeles International airports are well outside their respective city centres, and ground transfers can take 45 minutes to over an hour each way. Security, boarding and deplaning add more, and both airports can be congested.
Airlines including United, Southwest, American and Alaska fly the route, often at quite competitive fares for advance bookings. Flying makes the most sense if you are travelling light, have checked fares carefully against the time cost, or are based near the airport at one end. For a city-centre-to-city-centre comparison, the overall door-to-door time advantage over driving narrows quickly.
A note on alternatives: Oakland (OAK) and San Jose (SJC) airports can be more convenient than SFO and are worth checking. In LA, Burbank (BUR) or Long Beach (LGB) can save significant time for the right destination.
The cheapest way: the bus
Flixbus, Greyhound and other operators run between San Francisco (various stops, including the Salesforce Transit Center) and Los Angeles (most commonly downtown LA or the Hollywood area) in around 7 to 8 hours. Bus fares are typically the cheapest option on the corridor, particularly on advance bookings. The journey follows the I-5 through California's Central Valley — fast and practical, but not scenic. Overnight services let you wake up at the other end, which many budget travellers find a good trade.
Driving: two routes, two experiences
The drive between San Francisco and Los Angeles is about 560 km via the I-5, which takes roughly 5 to 6 hours without traffic. This is the fast, purely utilitarian option through flat agricultural land.
The alternative — Highway 1 (the Pacific Coast Highway) — is a different matter entirely. Clinging to sea cliffs south of San Francisco through Big Sur, passing Hearst Castle and hugging the coast past Malibu into LA, it is widely considered one of the most beautiful drives in the world. The distance is longer (around 650 km) and the journey time without stops is around 9 to 10 hours, but no one drives Highway 1 without stopping frequently. Budget two days minimum to do it properly.
Check current road conditions before setting off: parts of Highway 1 around Big Sur are sometimes closed due to landslides or storm damage, and the detour is significant.
Which should you choose?
If time is tight and cost is secondary, fly — but make peace with the airport experience at both ends. If you want a classic American train journey and can give up a fixed schedule, the Coast Starlight is genuinely special. The bus is the right choice on a strict budget. And driving has two personalities: the I-5 if you simply need to cover ground, or Highway 1 if the journey is the whole point.
Frequently asked questions
How long does the Coast Starlight take from San Francisco to Los Angeles?
The scheduled time varies, but expect roughly 9 to 12 hours including the bus connection from Emeryville into San Francisco. Delays are common, so treat it as a day journey rather than a timed connection.
Where does the train arrive in San Francisco?
The Coast Starlight stops at Emeryville, near Oakland — not in San Francisco itself. Amtrak runs a connecting Thruway bus from Emeryville to the Ferry Building area of San Francisco, included in your ticket. Book both legs together.
Is the Pacific Coast Highway open year-round?
Usually, but sections near Big Sur are occasionally closed due to landslides or storm damage. Check with California's Caltrans road information service before you travel, especially after heavy winter rains.
What is the fastest way from San Francisco to Los Angeles?
Flying is the fastest in terms of travel time, with the flight itself around 1 hour 20 minutes. When airport transfers and security are included, door-to-door time rises to 4–5 hours or more from city centre to city centre.
