Dive-site story
Set along the vertical cliffs of the Portofino Marine Protected Area, Grotta dei Gamberi is a deep cavern dive known for concentrations of crustaceans. Divers descend along a wall covered in gorgonians to reach the entry point. Inside the recess, clusters of cave shrimp reflect torch beams in red bands. This overhead environment demands disciplined gas management and decompression planning.
