Quick Answer
The best overall way to travel from Biarritz Airport to San Sebastián is the direct bus (E21/E27 line). It takes about 1 hour to 1 hour 15 minutes, costs approximately €18 one-way, and departs right outside the airport terminal. For the cheapest option (under €15), combine a local bus to Bayonne station with trains via Hendaye, but this takes over 1.5 hours with transfers. A taxi or private transfer is the fastest door-to-door option (35-50 mins) but costs €90-€120+.
Direct Bus: The Most Convenient Public Transport
The direct intercity bus is the undisputed champion for balance of convenience, cost, and speed. Operated by the Spanish company ALSA (marketed as “Interurbanos” locally), it connects the airport directly to San Sebastián's city center.
| Aspect | Details |
|---|---|
| Operator | ALSA / Interurbanos |
| Bus Line | E21 or E27 (Bayonne-San Sebastián) |
| Departure Point | Biarritz Airport (BIQ) bus stop, directly outside Arrivals. |
| Arrival Point | San Sebastián Central Bus Station (Estación de Autobuses de Donostia). |
| Journey Time | 60 - 75 minutes. |
| Frequency | Approx. every 1-2 hours from early morning until late evening. |
| One-Way Fare | ~€18 (Prices can vary; check ALSA's website). |
| Buying Tickets | Recommended online in advance via ALSA, or pay the driver with cash/card (subject to availability). |
| Luggage | Standard suitcase storage in the hold included. |
Why It's the Top Recommendation
This service eliminates the stress of multiple transfers. You board at the airport and disembark at a major transport hub in San Sebastián. The route is scenic, passing along the Basque coast. The main drawback is that the final bus station is a 25-min walk from the Old Town, but local buses (e.g., lines 9, 21, 26) or a short taxi ride easily solve this.
Key Tips for the Direct Bus
- Check the Timetable: Schedules change seasonally. Always verify the current timetable on the ALSA website.
- Book Ahead for Peak Times: During summer or festivals, buses can fill up. A pre-booked ticket guarantees your seat.
- Have Small Change Ready: If buying from the driver, having cash (Euros) close to the exact fare can speed up boarding.
Train via Bayonne & Hendaye: The Scenic & Flexible Route
While there is no single direct train, combining local bus and two train rides offers a scenic, if more complex, alternative. This route is ideal for rail pass holders or those starting their journey in central Bayonne.

Is This Route Worth It?
For most travelers, the direct bus is simpler. However, the train combo is valuable if: you have a Eurail Pass (covers Leg 2), you enjoy train travel, you miss the direct bus, or you are traveling from downtown Bayonne rather than the airport directly. The total journey time is at least 1 hour 50 minutes, excluding wait times between connections.
Taxi & Private Transfer: Door-to-Door Comfort at a Premium
For maximum convenience, privacy, or travel outside public transport hours, a taxi or pre-booked private vehicle is the solution. This is the fastest possible method, taking you directly to your hotel's address.
| Option | Details | Estimated Cost (One-Way) |
|---|---|---|
| Airport Taxi (Metered) | Official taxis are available at the airport rank. Ensure the meter is running. | €90 - €120+ |
| Pre-Booked Private Transfer | Book online in advance. Driver meets you at arrivals with a name sign. | €100 - €150+ |
| Rideshare (Uber/Bolt) | Availability can be sporadic and prices surge dramatically at the airport. | €80 - €130 (Highly variable) |
When Does a Taxi Make Sense?
Consider this option only in specific circumstances due to the high cost:
- Late-Night or Very Early Morning Arrivals/Departures when public transport is not operating.
- Traveling in a Group of 3-4 People, where the cost can be split, making it competitive with multiple bus/train tickets.
- If You Have Significant Mobility Issues or Excessive Luggage.
- For Business Travel where time and door-to-door service are paramount.
Important Taxi Advice
- Agree on a Price (or see the meter start) before departing. The fare should be based on the meter, but for an international trip, some drivers may quote a flat rate.
- Pre-booking a transfer (via companies like Welcome Pickups, SunTransfer, or local services) often provides fixed, guaranteed pricing and is highly recommended for peace of mind.
- The journey involves crossing an international border, but as per Schengen rules, no passport control will occur during the ride.

Money-Saving Tips & Passes
- No JR Pass: The Japan Rail Pass is irrelevant here. For France/Spain, look at the Eurail Global Pass or Interrail Pass, which only cover the Bayonne-Hendaye leg.
- Cheapest Possible Fare: Book the TER train (Bayonne-Hendaye) online in advance for lower prices (~€5). Combine with the cheap Chronoplus bus (€1) and Euskotren (~€3.30).
- Return Ticket: Sometimes a round-trip bus ticket offers a small discount compared to two one-ways.
Traveler Experience & Essential Tips
Beyond schedules and prices, these practical insights will make your journey smoother.

- Mobile Data: Your EU mobile plan should provide roaming in both France and Spain without extra charges. Confirm with your provider.
- Useful Apps: Download the ALSA app for bus tickets, SNCF Connect for French trains, and Google Maps or Citymapper for real-time local transit in San Sebastián.
Timing & Seasonal Advice
- Summer & Festivals (July-August, San Fermín in July): Book transport weeks in advance. Buses and trains fill up, and prices for taxis may be higher.

FAQs: Biarritz Airport to San Sebastián Travel
Is there a direct bus from Biarritz Airport to San Sebastián?
Yes, there is a direct bus service operated by ALSA/Interurbanos. The ‘E21’ or ‘E27’ line runs from Biarritz Airport (stop ‘Aéroport’) directly to San Sebastián's main bus station (Estación de Autobuses de Donostia). The journey takes about 1 hour to 1 hour 15 minutes and is the most straightforward public transport option.
What is the cheapest way to get from Biarritz Airport to San Sebastián?
The cheapest way is a combination of local bus and train. First, take the Chronoplus C line 14 bus from the airport to Gare de Bayonne (€1, 50 mins). Then, take a TER train from Bayonne to Hendaye (€5-10, 30 mins), and finally a short Euskotren from Hendaye to San Sebastián (Amara station, ~€3, 35 mins). Total cost can be under €15, but the direct bus (€18) offers better value for simplicity.
How long is the taxi ride from Biarritz Airport to San Sebastián?
A direct taxi or private transfer between Biarritz Airport and central San Sebastián takes approximately 35 to 50 minutes, depending on traffic at the border. The distance is about 50 km (31 miles).
Can I use a Eurail or France Rail Pass for this trip?
Yes, but with limitations. Eurail Global Pass and France Rail Pass cover the SNCF TER train from Bayonne to Hendaye. However, they do NOT cover the subsequent Euskotren (Hendaye to San Sebastián) or the direct bus from the airport. You will need to purchase a separate ticket for the final leg in Spain.
Is it better to fly or take the train/bus from Biarritz to San Sebastián?
Taking the train/bus is unequivocally better. There are no direct flights. The closest airports are Biarritz (BIQ) and San Sebastián (EAS), which are only 50 km apart. Flying would require connecting through a major hub like Paris or Madrid, turning a 1-hour land journey into a 6+ hour ordeal with high cost and carbon footprint. Land transport is faster, cheaper, and more practical.
How do I get from Biarritz Airport to San Sebastián late at night?
Late-night options are very limited. The last direct bus (E21/E27) typically departs around 10:30 PM. The last trains from Bayonne to Hendaye usually run until about 11:30 PM. After these times, your only reliable option is a pre-booked taxi or private transfer. We strongly recommend booking this in advance if you have a late arrival.
Where exactly does the bus from Biarritz Airport stop in San Sebastián?
The direct ALSA bus terminates at the San Sebastián Central Bus Station (Estación de Autobuses de Donostia), located at Pío XII plaza, 1. This station is about a 25-minute walk or a short bus/taxi ride to the Old Town (Parte Vieja) and most central hotels.
Is the border crossing between France and Spain complicated on this route?
No, it's very straightforward. France and Spain are both part of the Schengen Area, meaning there are no passport controls or border checks for land travel. You will cross the border on the bridge over the Bidasoa River between Hendaye (FR) and Irun (ES) without stopping. You likely won't even notice it.
