Dive-site story
Located off the rugged southern coast of Lanai, Wash Rock centers on a submerged volcanic pinnacle whose summit breaches the wash zone in heavy swell. Underwater, the volcanic structure drops into a complex landscape of undercut basalt ledges, arches, and rubble-strewn channels. Sunlight filters through crevices to illuminate resting whitetip reef sharks and tucked-away morays, while schooling reef fish patrol the surrounding current-washed perimeter.

Seasonality
Calmer surface conditions generally prevail during late spring through early autumn, though south swells occasionally affect surge.
