Dive-site story
Located off the coast of Baja California just south of the United States border, the Coronado Islands archipelago is an iconic cold-water Pacific diving destination. Thick forests of giant kelp anchor to volcanic rocky reefs, providing shelter for an abundant marine ecosystem. Inquisitive California sea lions frequently join divers in the shallows, darting between kelp stalks while large schools of temperate fish drift across sheer boulder slopes.
Playful interactions with resident California sea lions around the rocky coves
Expansive giant kelp canopies sheltering bright orange garibaldi and kelp bass
Atmospheric underwater topography featuring boulder drops, crevices, and rocky archways
Location
