Dive-site story
Formed within an extinct volcanic caldera in the Alban Hills south of Rome, Lake Nemi offers freshwater diving steeped in classical history. Divers navigate muddy slopes, submerged tree trunks, and shallow beds of aquatic plants. While Caligula's famous Roman ships were salvaged in the early twentieth century, the lake floor still attracts divers interested in historical exploration, altitude diving, and low-visibility training.
