This dive site, Fényes-forrás, is a unique freshwater destination in Hungary, comprising five interconnected lakes fed by a constant natural thermal spring. Located along the Tatai Fényes-Tanösvény Trail, divers can explore a shallow, warm environment. Navigation is likely straightforward within the small lake system, with recommended areas being Katonai and Körtefás lakes. There's no specific historical dive event mentioned, but the site's allure lies in its natural thermal origins.
As a freshwater thermal spring, the site is unlikely to host marine animals like coral reefs or ocean fish. Instead, divers can expect to encounter various freshwater aquatic plants, potentially unique microorganisms, insects, crustaceans, and native freshwater fish species adapted to the spring environment. The thermal nature might support specific flora and fauna not found in typical cold-water lakes.
The constant thermal spring ensures diving is suitable year-round, with the water temperature remaining a comfortable 21 degrees Celsius. This makes Fényes-forrás an excellent spot for off-season diving or for those seeking warm water experiences. It's particularly ideal for beginner divers and underwater photographers focusing on macro subjects and unique freshwater landscapes. Freedivers will also find the shallow, clear conditions perfect for training or leisurely exploration.
