Pantano de la Sotonera – Inland Freshwater Sites
Site Overview
The Pantano de la Sotonera is a reservoir in Huesca whose waters hide a submerged church and village, a haunting freshwater site for training and exploration. Calm and sheltered, it offers easy diving with the novelty of swimming over rooftops and bell towers in clear seasons. Beginners build skills here while more experienced divers explore the structures, and the surrounding Pyrenean foothills add scenery. Sotonera is a classic Spanish inland reservoir dive. 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.
