Boat-only deep ridge off Mataró for advanced divers.
Boat access and the deep profile make a local operator the practical way to dive Arrecife.
Arrecife is a boat-only offshore rocky ridge off Mataró with a deep, gravelly profile and enough relief to reward careful buoyancy and relaxed gas planning. It suits advanced or deep-certified divers who want a longer run with morays, nudibranchs, lobsters, and schooling fish around the structure. Plan it for settled sea states rather than as a casual stop.
