The summer Arrives, the Sea Awakens, and Cantabria Has Something Special to Tell You. Every year, June brings with it one of the most celebrated events in the global surfing community: International Surfing Day. A day dedicated to honoring a sport that blends strength, balance, respect for the ocean, and a generous dose of adrenaline. And if there is one place in Spain where this occasion deserves to be celebrated in all its intensity, that place is Cantabria.
