Hydronauta operates from Ribeira, in the Ría de Arousa, the largest of the Rías Baixas. Galician rías are unique estuaries where nutrient-rich Atlantic waters create ecosystems of extraordinary abundance.
Seabeds include kelp forests, rock formations, sandy bottoms, and the famous ría biodiversity. The mix of fresh and salt water creates unique conditions for marine life.
Galician Atlantic fauna is impressive: lobsters, spider crabs, octopuses, conger eels, sea bass, and invertebrate biodiversity unique in Europe. Cold waters concentrate life in abundance.
Hydronauta is ideal for divers seeking the Galician Atlantic at its finest with dives in unique ría ecosystems found nowhere else.
