The nearest airport is only half the answer
- San Sebastian Airport (EAS) is the nearest airport, about 20-22 km from the city centre in Hondarribia.
- Aena currently lists nine destinations served by five airlines, so EAS is convenient but route-limited.
- The airport bus is the budget option; a taxi is usually the least stressful option.
- Biarritz is the closest alternative, while Bilbao gives you the widest flight choice.
- For a short city break, I would usually prioritise transfer simplicity over raw distance.
San Sebastian Airport is the nearest, but not always the best choice
The nearest airport is San Sebastian Airport (EAS), and I treat it as the default answer for a first-time visit. It sits in Hondarribia on the Bidasoa estuary, about 20-22 km from Donostia/San Sebastian, and the route network is small enough that you should think of it as a convenience airport rather than a big connection point. That still makes it the easiest arrival for many trips, especially when the flight lineup fits your dates.
What matters is that the airport is useful, but not broad. I would expect core domestic links first, with only a handful of international options, so I always check the schedule before assuming EAS will work for every departure day.
That leaves one practical question: how do you actually get from the terminal into the city in the cleanest way?
How to get from the airport into the city
The airport is close enough that transfer choice should be based on comfort, not panic. If I’m travelling light, arriving in daylight, and staying central, the bus is fine. If I’m tired, landing late, or carrying real luggage, I usually pay for the taxi and move on with the day.
Bus
Lurraldebus services operated by Ekialdebus connect the airport with Hondarribia, Irun, Renteria and San Sebastian. The year-round E21 and the summer E30 are the two names worth remembering if you want a simple public-transport arrival. The fare depends on how many districts the route crosses, so this is not a flat-rate airport shuttle in the way many bigger cities use them.
I like it for budget travel because it keeps the arrival cheap without turning it into a long puzzle, and the MUGI card can be bought at the airport duty-free shop if you want to use wider public transport in Gipuzkoa. If you are heading to the Old Town, Gros, or Amara, I would check the timetable before landing and avoid assuming the same frequency all year. The summer E30 is especially useful, but outside the high season I would still verify the exact return journey before I commit to the bus.
Taxi
Spain.info puts a taxi from the airport to Donostia/San Sebastian at roughly EUR 30-33, with airport minimum fares of EUR 4.80 on weekdays and EUR 5.65 at nights, weekends, and public holidays. That is not cheap, but for a short city break it is often the best use of money if you want a direct hotel drop-off and no waiting around.
In my view, taxi value rises fast when you are arriving late, travelling with family, or carrying more than a cabin bag and a backpack. San Sebastian is compact, so the extra spend usually buys you a cleaner start to the trip.

Car hire
I would only rent a car at EAS if San Sebastian is one stop in a longer Basque Country itinerary. For a city-centre stay, parking and one-way traffic are enough friction that a car often becomes a burden rather than a convenience. If your trip includes Hondarribia, the coast, or inland villages, then a car makes much more sense.
Once you see the transfer options clearly, the next comparison is whether another airport gives you a better total journey.
Why Biarritz or Bilbao can be smarter
On a map, Biarritz looks temptingly close and Bilbao looks far enough away to be dismissed too quickly. I would not do that. The real choice is whether you want the shortest road transfer, the most practical regional connection, or the widest choice of flights, because those three things do not always point to the same airport.
| Airport | Distance from San Sebastian | Best for | Main trade-off |
|---|---|---|---|
| San Sebastian (EAS) | 20-22 km | The quickest and simplest city arrival | Limited destinations and thinner schedules |
| Biarritz (BIQ) | 40-45 km | Cross-border flexibility and some useful regional options | More planning if your transfer depends on bus timing |
| Bilbao (BIO) | 100-105 km | Wider flight choice and more frequent departures | Longer transfer into San Sebastian |
If I’m travelling on a budget, I compare the whole trip rather than the airfare alone. A slightly cheaper ticket into Bilbao can still lose once you add the coach and the extra time on the road, while Biarritz can be the sweet spot if the fare and transfer line up neatly. That is why a map search is never enough on its own.
The airports that look simple at first glance are often the ones travellers misjudge, and that leads straight into the common booking mistakes.
The booking mistakes that cost travellers time and money
There are a few errors I see again and again, and they are all avoidable.
- Choosing the nearest airport without checking whether the flight times suit your day.
- Assuming a small airport will have the same flexibility as a major hub.
- Ignoring seasonality and finding out too late that a bus option is weaker than expected.
- Saving a small amount on the ticket, then paying it back on the ground transfer.
- Booking a late arrival and assuming public transport will still feel easy.
I would also re-check the airline and the route before paying, because small airports feel schedule changes more sharply than large ones. The safer habit is to calculate the trip door to door, not just the airfare. If that sounds obvious, it should, but it is exactly where a lot of people lose time and money.
From there, the decision becomes much easier when I match the airport to the type of trip.
Which airport I’d choose for different trips
For a weekend city break, I would choose San Sebastian Airport first and pay a little more if necessary. For a longer Basque road trip, I would compare Bilbao much more seriously, because its flight choice can outweigh the extra distance. If I wanted a cross-border route or a convenient alternative with good regional links, Biarritz would stay on my list.
| Trip type | My pick | Why I’d choose it |
|---|---|---|
| Short city break | EAS | Least friction from plane to hotel |
| Late arrival | EAS + taxi | I want the fewest moving parts after landing |
| Best fare on flexible dates | Bilbao | More flights usually means more pricing competition |
| Cross-border itinerary | Biarritz | Useful if you are combining France and Spain |
The pattern is simple: if convenience is the priority, the nearest airport wins; if flight choice matters more, the bigger airports can justify the extra ground time. I always decide that before I buy, not after I land. That one habit removes most of the stress from the arrival.
The arrival plan I’d use for San Sebastian
If I were planning the trip today, I would search San Sebastian Airport first, then compare Biarritz and Bilbao only if the fare or timetable clearly improved the journey. That keeps the decision practical: the nearest airport for the smoothest arrival, Bilbao for more options, and Biarritz when it offers the best mix of timing and cost.
For San Sebastian, that is the real rule I would use. The city is small, so the best airport is usually the one that gives you the least friction from the terminal to your accommodation, not just the shortest number on a map. Once you think that way, the right choice is usually obvious.
