Direct intercity coaches from Bilbao Airport are rare; plan for Bilbao Intermodal first
Most long-distance coaches (ALSA, PESA) for San Sebastián/Donostia, Vitoria‑Gasteiz, and Santander leave from Bilbao Intermodal/Termibus, not from T1 at BIO. Even if your end goal is Donostia, you usually ride the A3247 airport bus into the city, then connect to a regional coach. That detour adds 15–20 minutes from T1 to Intermodal before your real trip even starts.
Regional coach times from Bilbao Intermodal sit around 1 hour 15 minutes to San Sebastián, about 1 hour to Vitoria‑Gasteiz, and roughly 1 hour 30 minutes to Santander on ALSA or PESA. Typical one‑way fares land in the €25–30 range on the faster services, with cheaper options off‑peak. Schedules can bunch, so on some routes you might see a 3–4 departures per day pattern rather than true hourly service.
Almost all tickets are sold online now, and QR codes from the ALSA or PESA apps scan fine on phones, according to recent Reddit reports. Paper tickets from machines or station counters still exist, but regulars complain that queues spike 20–30 minutes before a 50‑seat coach leaves. If you like printed tickets, arrive at Bilbao Intermodal early enough to stand in that line without sweating your departure time.
Seasonal and weekend‑only coaches complicate things further. Some seaside routes from Bilbao Intermodal only run in July–August or just on Saturdays and Sundays, and a few drop to 1–2 departures per day off‑season. People who got burned in past summers now triple‑check the day‑of‑week on ALSA/PESA timetables and avoid assuming that a Friday schedule matches a Monday.
Connections from BIO can feel tight. Reddit regulars recommend building at least a 30–45 minute buffer between the scheduled A3247 arrival at Bilbao Intermodal and your intercity coach departure. Factor in a 10‑minute delay on the airport bus plus 10 minutes to find the right bay and load bags under the coach, and that 45‑minute gap starts to look sensible, especially for last buses of the day.
Luggage can be chaotic on busy dates such as Easter, early August, or long weekends. With a full 55‑seat ALSA coach, you may see 40–50 large suitcases going into the hold and little direct guidance from a single driver. Tag your bag, place it yourself near the middle doors if you exit early, and keep valuables in a small backpack in the cabin rather than in the hold.
Step-by-step: using intercity buses from Bilbao Airport
- 1. Land at T1 and exit arrivals: Clear baggage claim in T1 at BIO and walk out to the A3247 bus stop; expect a 15–20 minute ride into Bilbao Intermodal.
- 2. Ride A3247 to Bilbao Intermodal: Pay the airport bus fare on board or with Barik and note the scheduled arrival time at Intermodal; build in a 10–15 minute delay margin.
- 3. Find your coach bay at Intermodal: Inside Bilbao Intermodal, check screens for ALSA or PESA departures to San Sebastián, Vitoria‑Gasteiz, or Santander, and note the exact platform number.
- 4. Buy or pull up your ticket: If you did not buy online, use machines or counters to purchase a €25–30 ticket; otherwise open your QR code in the ALSA/PESA app for scanning.
- 5. Load bags and board: Arrive at the coach 10–15 minutes before departure, place large luggage in the hold yourself, and keep documents and electronics with you in the cabin.
One last tip: if your flight lands after 20:00 and you still need an intercity coach, check the very last departure of the day and consider booking a flexible fare in case your plane or the A3247 slips by 20–30 minutes.
