San Sebastián
Winters are cloudy and wet (though still warm), making summer the ideal time to visit. The population of the city increases considerably from June through August, but unlike other European cities, the crowds aren't large enough to make a trip unpleasant. San Sebastián’s food scene is delicious all year round, though restaurant hours can be limited in the winter. To really live like a local, plan a trip around one of San Sebastián’s many festivals, when the city comes alive with, say, film buffs (September's San Sebastián Film Festival), drummers (January's Tamborrada festival), farmers (December's Santo Tomas), and summer revelers (August's Great Week).
