Asturias & Cantabria (Cantabrian Sea)

About Asturias & Cantabria (Cantabrian Sea)

Green Spain’s Cantabrian coast offers cool, clear temperate diving with kelp forests, dramatic blowholes and rich invertebrate life. The Isla de la Deva reserve near Luanco has steep, kelp-clad walls thick with spider crabs, lobsters and octopus, while Lastres adds underwater blowholes and caves. Ribadesella’s Cueva del Agua is a guided cavern with stalactites, and Santander’s Isla de Mouro holds lobsters and sea fans. Santoña rounds it out with kelp and wrasse. Limited access and unspoiled conditions make this a pristine, under-the-radar region for confident Atlantic divers. This region rewards careful planning and respects Spain’s marine-protection rules, offering rewarding diving across a wide range of experience levels through a long and varied season.
