Two trains, one coastal track. This page is the side-by-side — the full COASTER how-to lives on its own guide.
Last updated
Inside San Diego County, take the COASTER: it is roughly a third of the price, stops at more beach towns, and reaches Solana Beach, Encinitas, Carlsbad and Oceanside from downtown. Take Amtrak's Pacific Surfliner when you are leaving the county — Anaheim, Los Angeles, Santa Barbara and San Luis Obispo — or when you want a reserved seat, a cafe car and a guaranteed spot on a busy weekend. Both use the same tracks and the same downtown station (Santa Fe Depot), so the decision is really about distance and comfort, not route. For a step-by-step COASTER how-to — fares, PRONTO, timetables, bike and board rules — use the dedicated COASTER train guide.
| COASTER | Pacific Surfliner (Amtrak) | |
|---|---|---|
| Runs between | Santa Fe Depot ↔ Oceanside (8 stations) | San Diego ↔ LA, Santa Barbara, San Luis Obispo |
| One-way fare from downtown | About $5.50–$7 | About $16–$20 to Oceanside, ~$45 to LA |
| Booking | Tap-and-go with PRONTO, no reservation | Reserved seat, book ahead on busy days |
| Stops in the county | Old Town, Sorrento Valley, Solana Beach, Encinitas, both Carlsbad stations, Oceanside | Old Town, Solana Beach, Oceanside only |
| Seats and amenities | Commuter seating, restrooms, bike cars | Wider seats, tables, cafe car, checked bags |
| Best for | Beach days, commuting, cheap county trips | LA and Orange County, long trips with luggage |
Rates and availability change daily, so we link the guide rather than quote a price. Each page compares walkable, short-drive and budget options with parking and resort fees called out.
Almost every real decision comes down to four trips. The full COASTER operating detail is on the COASTER train guide.
Take the COASTER. It stops at Solana Beach, Encinitas and both Carlsbad stations, all within a short walk of sand, and the Surfliner skips most of them entirely for triple the fare.
Local tip: Read the COASTER train guide for fares, PRONTO tapping and the weekend timetable before you plan the return leg.
Take the Surfliner. The COASTER stops at Oceanside, so the only alternative is a transfer at Oceanside onto Metrolink, which is cheaper but adds a wait and a change with luggage.
The Surfliner wins even for in-county trips: reserved seats, luggage racks and checked-bag service at staffed stations. The COASTER has no reservations, so a summer Saturday can mean standing.
Neither train serves the terminals. Both drop you at Santa Fe Depot; from there MTS Route 992 or a short rideshare finishes the trip.
The same tracks, further north, with reserved seats.
From the Santa Fe Depot the Surfliner runs up through Solana Beach and Oceanside to Anaheim, Los Angeles Union Station, Santa Barbara and San Luis Obispo. Downtown San Diego to LA takes about three hours.
Local tip: Sit on the west side of the train heading north — the stretch between Del Mar and San Clemente runs right along the bluffs.
Any weekday trip to Los Angeles or Anaheim. Traffic on I-5 through Orange County routinely makes the drive slower than the train, and you skip $40-a-day LA parking.
The bluffs at Del Mar and the tracks through San Clemente have been closed for stabilization work several times in recent years, with buses bridging the gap. Check the Pacific Surfliner alerts page before booking.
Operators change fares and timetables on their own schedule. Every number below is checked against the operator's own page on the date shown — check the source link before you travel.
Adult one-way fare: $5.00 for 1 zone, $5.75 for 2 zones, $6.50 for 3 zones
Verified Sep 19, 2026 against NCTD — Bus & Train Fares + Passes — view the source
Announced change effective 2026-10-01: $6.50 flat adult one-way fare, all zones (SANDAG Phase I); a further Phase II increase is planned for 2027
Roughly $5.50 to $7 one way depending on how many zones you cross, paid with the PRONTO app or card. Daily fare capping means heavy travel days stop charging you after a point.
The Coaster is the local commuter train between downtown San Diego and Oceanside. Amtrak's Pacific Surfliner uses the same coastal tracks but continues to Los Angeles and Santa Barbara, with reserved seating and higher fares.
Yes. Solana Beach, Encinitas and Carlsbad Village stations are all within a ten-minute walk of the sand, which makes the Coaster the best car-free beach option from downtown.
No. Use MTS Route 992 from the Santa Fe Depot or downtown, or a rideshare from the Transportation Plaza.
Often, on weekdays. The Surfliner takes about three hours downtown to downtown and avoids I-5 traffic through Orange County plus LA parking costs.
