HOW TO GET THERE. It’s possible to fly to San Sebastián via Barcelona with Vueling, but perhaps a better option is to fly direct into Bilbao, just over 60 miles from San Sebastián, or to Biarritz, 30miles away over the French border. BA, EasyJet and Vueling fly direct to Bilbao from London airports; Ryan air flies direct from London Stansted to Biarritz. If you are following our route exactly, buy a single fare and make your return journey from Santiago de Compostela.
