Lago de Sanabria – Inland Freshwater Sites
Site Overview
Lago de Sanabria is Spain’s largest natural lake, a deep glacial basin reaching 51 m with a submerged valley and remarkably clear, cold freshwater. Advanced divers explore the drop-offs and the drowned landscape, meeting trout and pike and the occasional freshwater sponge in the blue. Its altitude and depth demand careful planning and thermal protection, making it a serious but beautiful inland dive. Sanabria is a unique Spanish freshwater destination surrounded by a protected natural park. 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.
