Carmen Island Wall
Loreto · Mexico
Carmen Island's east-facing wall is the premier technical dive in the Loreto archipelago — a near-vertical drop from 8 m that plunges past 40 m into cobalt blue water, encrusted with dense black coral forests, orange cup corals, and sea fans that attract clouds of creole fish and chromis sheltering from the current. Schools of scalloped hammerheads drift past in the blue water column between July and November, sometimes in groups exceeding 50 individuals, while the wall's shallower ledges harbour garden eels, moray eels, and the occasional sleeping whitetip reef shark. The consistent thermocline at around 18 to 22 m can drop water temperature sharply, requiring a thicker exposure suit than conditions above might suggest.
