San Sebastián is the finest food city in Europe by almost any measure — more Michelin stars per capita than anywhere else on earth, a pintxos bar culture in the Parte Vieja that sets the standard for all bar food everywhere, and a location on a perfect bay in the Basque Country that gives it one of the finest urban beaches in the world. La Concha beach, with the island of Santa Clara in its middle and the hills of Monte Igueldo and Monte Urgull on either side, is the most beautiful bay in Europe. The combination of exceptional food, extraordinary scenery and a genuinely proud Basque identity makes it unlike anywhere else in Spain.
From London and several UK airports it's under two hours — Ryanair and easyJet fly to Biarritz (45 minutes from San Sebastián by bus) and to Bilbao (70 minutes by bus). The city is best from May to October: the beach is at its finest, the outdoor pintxos culture is in full swing and the Semana Grande festival in August is the most vibrant week in the Basque calendar. The weeks around the San Sebastián Film Festival (September) and the Jazz Festival (July) are worth planning around. November to April is quieter, wetter and significantly cheaper.
