About Secca del Mariuolo
Secca del Mariuolo is a rocky shoal off Zannone with a shallow cap, a drop-off, small caves, and narrow cracks. The site rewards slow exploration around the rock tower rather than a straight drift, and it is best approached by boat when the weather is settled. Its appeal is the broken relief, the overhead pockets, and the mix of Mediterranean fish and larger hunters around the structure.
