Bilbao Airport to City Center — What You Actually Need to Know

Bilbao Airport (BIO) sits about 12 km north of the city center in Loiu. The most common ways to reach downtown are the Bizkaibus A3247 (EUR 5 for a single ticket without a Barik card, roughly 25 minutes to Plaza Moyua) or a taxi (EUR 27 on workdays and EUR 30 on public holidays to Bilbao (fares published by Aena, the airport operator), 15-20 minutes depending on traffic). If you have a pre-booked private transfer, expect similar drive times but with the comfort of someone waiting for you in arrivals.

BIO is a single-terminal airport, so navigation is straightforward. After passport control (if applicable) and baggage claim, you walk out into the arrivals hall. The terminal was designed by Santiago Calatrava, and while it looks impressive, the layout is simple.

The bus stop is directly outside the arrivals exit, clearly signed. Taxis queue right next to it. There is no train station at the airport, so rail is not an option here.

One thing to note: Bilbao is in the Basque Country, so signage is in both Basque (Euskara) and Spanish. Do not be confused if place names look unfamiliar — the Spanish versions are always displayed alongside.

The Bizkaibus A3247 is reliable. Per Aena, it runs from the airport into Bilbao between 06:10 and 23:40, every 15 minutes, stopping at Gran Via 79, Plaza Moyua and Alameda Recalde 11 before Termibus. A single ticket is EUR 5 if you do not have a Barik card; with a Barik card the Creditrans fare for the zone is EUR 1.19. You can pay by card at the Bizkaibus cabin at the airport.

Taxis are metered and regulated, so there is no negotiation involved. The rank is right outside arrivals. Aena publishes the fare to Bilbao as EUR 27 on workdays and EUR 30 on public holidays. Fares are revised, so check the current tariff posted at the rank before you travel.

If you are heading somewhere outside central Bilbao — say, San Sebastian (about 100 km east) or the Rioja wine region — a pre-booked transfer makes much more sense than a metered taxi.

The bus is genuinely cheap at EUR 5 — EUR 1.19 with a Barik card — and hard to beat for solo travelers. Aena's fare guidance for the airport rank covers the ride into Bilbao itself:

The EUR 27/30 figure above is Aena's guidance for the Bilbao city run only — it does not extend to destinations outside the metro area. For San Sebastian, Pamplona, Burgos or anywhere else further out, taxis run purely on the meter with no published fixed rate, so a pre-booked transfer is the more predictable option. Within central Bilbao, taxis and transfers are comparable.

Per Aena, the last A3247 into Bilbao leaves the airport at 23:40. If your flight lands close to that, clearing baggage in time is a gamble, and later arrivals will need a taxi or pre-booked transfer.

The taxi rank outside arrivals operates around the clock, so you will not be stranded. Aena's published fare list distinguishes workdays from public holidays (EUR 27 and EUR 30 to Bilbao); any other supplement is set by the regulated tariff and shown on the meter, so check the tariff posted at the rank. Pre-booked transfers avoid the uncertainty — your driver will be there regardless of delays.

The airport itself is quiet at night. Do not expect many food or shopping options after the last flights.

The A3247 bus can handle regular luggage, but if you are traveling with strollers, car seats, and multiple suitcases, it becomes impractical. The bus storage area is limited, and during busy times you may need to hold bags on your lap.

Taxis at BIO are mostly sedans. If you have more than two large suitcases, request a larger vehicle at the rank or book a minivan transfer in advance.

Child car seats are not provided in regular taxis. If you need one, a pre-booked transfer is the only reliable way to guarantee it. Spanish law requires appropriate child restraints for children under 135 cm.

For taxis, walk straight out the arrivals exit and the rank is immediately to your right.

For pre-booked transfers, drivers typically wait in the arrivals hall holding a name sign. The meeting point is usually near the exit doors, close to the information desk. Your transfer company will confirm the exact spot when you book.

The terminal is small enough that finding anyone is straightforward — there is only one arrivals exit.

Take the bus if: you are traveling solo or as a couple with light luggage, arriving during daytime hours, and your accommodation is near a bus stop on the A3247 route.

Take a taxi if: you want door-to-door service without pre-planning, have moderate luggage, and are comfortable with metered pricing.

Book a private transfer if: you are traveling with family, arriving late at night, have lots of luggage, need a child seat, or are heading outside central Bilbao. The fixed price and guaranteed availability remove the guesswork.
