Dive-site story
Located off the coast of western Sicily near Trapani, Tre Massi is named after three massive limestone boulders rising from a sandy seabed surrounded by Posidonia oceanica meadows. Divers navigate through the channels, small swim-throughs, and overhangs formed by these submerged monoliths. The rocky surfaces are carpeted with encrusting sponges and bryozoans, offering shelter to Mediterranean reef fish, octopuses, and crustaceans.
