Key Dive Site Facts
Dive Site Overview
Secca delle Fumose presents a unique underwater environment shaped by both ancient human endeavor and ongoing volcanic activity. Divers will find several historical pylons, thought to have once protected the ancient Portus Julius, now colonized by diverse marine life.
These submerged structures offer a complex topography to explore. A defining characteristic of the site is the presence of active fumaroles; these are columns of gaseous bubbles that emanate from the seabed, a clear indication of the area’s volcanic origin. Sulfur deposits are often visible across the seabed, adding to the distinctive geological feel.
Reaching a maximum depth of 12 m (39 ft), the site is accessible for various certification levels, primarily through boat entry. The saltwater environment cradles a vibrant ecosystem around these unique geological features, making for an engaging dive.
