Ribadesella – Cueva del Agua – Asturias & Cantabria (Cantabrian Sea)
Site Overview
The Cueva del Agua is a large sea cave at Ribadesella, its chambers decorated with stalactites and holding air pockets that divers can surface into on a guided cavern dive. Glassfish and morays inhabit the clear, cool water, and careful buoyancy keeps the silty cave pristine. Advanced divers explore the overhead environment while respecting the fragile formations, and the surrounding Sella estuary adds beauty. Cueva del Agua is a highlight of the Asturian coast. The site rewards careful planning, good buoyancy and respect for Spain’s marine-protection rules, and remains a favourite among divers who value dramatic volcanic or Mediterranean scenery, historic wrecks and rich marine life across a long, varied season.
