Montseny is a nitrox-friendly Barcelona boat dive
Montseny is a boat-access rocky bar off the Barcelona coast, with an oval profile, Mediterranean fish life, and enough average depth that nitrox is a sensible choice. It is a measured dive rather than a shallow shore splash, and it suits divers who like clean rock structure, good visibility, and a calm working pace in settled seas.
