The question everyone asks
When you land at Bilbao Airport (BIO) heading for Biarritz, almost everyone looks for the same thing: "is there a direct train or bus?". The short answer is no. The French Basque coast is well connected internally, but the Bilbao Airport ↔ Biarritz public transport connection is one of the worst in the region. Here is why.
Option 1: Bus (with transfers)
There is no bus that directly links the airport with Biarritz. The typical route is:
- Bizkaibus A3247: from the airport to central Bilbao (Termibus / Moyua), about 20-30 min.
- Bus Bilbao → San Sebastián: PESA/ALSA companies, around 1h15-1h30.
- San Sebastián → Hendaye/Biarritz: transfer to a cross-border bus or the French network, with waits.
Realistic total: 3 hours or more, with 2-3 transfers, waits between connections and luggage always in tow. Any delay on a link breaks the whole chain.
Option 2: Train (Euskotren + SNCF)
The train is no more convenient either:
- First you have to reach central Bilbao from the airport (there is no train at the terminal).
- Euskotren connects Bilbao with San Sebastián and Hendaye, but it is a slow commuter train with many stops (over 2h30 just to Hendaye).
- At Hendaye you transfer to the French network (TER / SNCF) to reach Biarritz station, which is also on the outskirts, several kilometres from the centre and the beaches.
Total: 3h30 or more, and on arrival you still need a local taxi to get from Biarritz station to your accommodation.
Option 3: Rental car
Renting a car at Bilbao Airport is possible, but it has drawbacks for a short trip: parking in Biarritz is expensive and scarce in summer, you add fuel and tolls, and driving through an unfamiliar tourist town with restricted-traffic zones costs time and peace of mind.
Option 4: Private door-to-door taxi
This is where the taxi makes the difference on this particular route. Instead of chaining buses and trains for 3 hours, the taxi takes you straight from the terminal to the door of your hotel in Biarritz in 1h30-1h45, at a closed fixed price.
| Option | Price | Time | Door to door |
|---|---|---|---|
| Private taxi (fixed price) | From €185 / vehicle | ~1h30 – 1h45 | ✅ Yes |
| Bus (with transfers) | Variable + tickets | 2h30 – 3h | ❌ No |
| Train + transfer | Variable + tickets | 3h – 3h30 | ❌ No |
| Rental car | Rental + fuel + parking | ~1h45 | Partial |
For two, three or four people, splitting the taxi's fixed price gives a very reasonable per-person cost, and you gain over an hour and a half and zero transfer stress. You can book your taxi from Bilbao to Biarritz at taxibilbaoaeropuerto.com.

| Timetable | Limited | 24/7 |
| With flight delay | You can miss links | Flight tracking |
The problem of timetables and last connections
A factor few consider when planning the public transport trip is the timetable. Intercity buses and commuter trains stop running relatively early, and cross-border links are even more limited. If your flight lands at Bilbao Airport late in the afternoon or at night, you very likely won't manage to chain all the connections the same day.
This forces many travellers to overnight in Bilbao or San Sebastián halfway, with the cost and lost time that entails. The taxi runs 24/7: whatever time your flight arrives, the transfer is direct to Biarritz.
What if my flight is delayed?
On public transport, a flight delay can make you miss the first link, and with it the whole chain of connections. Recovering the itinerary can cost hours. With a booked taxi and flight tracking, the driver knows your real landing time and adjusts the pick-up: you lose nothing even if the plane arrives late.
Real cost: not just the ticket
When comparing prices, look at the total cost, not just the bus or train ticket:
- Public transport adds several tickets (Bizkaibus + intercity bus/train + French link).
- Add the local taxi you'll need on arrival, because Biarritz station is far from the centre.
- And the value of your time: 1h30-2h extra spent on platforms and waiting.
For two or more people, once you add it all up, the private taxi at a fixed price stops being "the expensive one" and becomes the most sensible choice.
When does each option pay off?
- Travelling alone with plenty of time and a tight budget: public transport is possible, though long.
- Travelling as a couple, family or group: the taxi almost always wins on time, comfort and, split, on price too.
- Arriving at night or with a delayed flight: the taxi is the only reliable option, as public transport links are scarce out of hours.
- Carrying bulky luggage (surfboards, big suitcases): the taxi is the only comfortable option.
