Dive-site story
Set along the eastern shoreline of the Sea of Cortez, the waters off San Carlos feature volcanic rock reefs, steep drop-offs, and isolated offshore pinnacles. Submerged boulder fields shelter dense colonies of macro invertebrates, while surrounding channels draw pelagic schools. Divers encounter both calm inshore bays suitable for basic skills work and exposed rocky points where tidal movements pull in large predatory fish.
Interactions with California sea lions around nearby offshore rocky haul-outs
Expansive rocky reefs colonized by gorgonians and sea fans
Macro hunting among volcanic rubble for nudibranchs, blennies, and jawfish
Occasional schools of mobula rays cruising past open-water points
