The closest airport to Markulluko Borda Rural Suites is San Sebastian Airport (EAS) and there are two ways to get there:
By cab, which takes 40 minutes and costs around 60€
By bus from both Pamplona and Donostia with the company LA BAZTANESA, which is the bus that goes to the center of Elizondo. You can also fly to Bilbao Airport (BIO), which is a little further away, but has better connectivity and a wider range of flights.
