Dive-site story
Located north of Isla Partida within the Espiritu Santo Archipelago, this pair of rugged rock outcrops supports a permanent rookery of California sea lions. Divers navigate boulder fields, rocky walls, and a natural submerged archway where juvenile sea lions frequently dart around divers, tugging at fin tips or blowing bubbles. Beyond the marine mammals, the surrounding sandy slopes and rocky ledges host large schools of baitfish, hunting jacks, and macro critters.
