Dive-site story
Shark Fin is an iconic volcanic rock formation rising above the surface off the southwest coast of Lanai. Below the waterline, the site features dramatic underwater lava tubes, caverns, and expansive coral encrustations that drop down along rocky ledges. Divers frequently encounter resting whitetip reef sharks sheltered inside the deeper undercuts.
