    StandoutDramatic cave topography

    The Cathedrals in Lanai offer a unique cave diving experience, renowned for its two large lava tubes. Sunlight streams through cracks in the ceiling, creating an almost stained-glass effect. We often find turtles resting inside and schools of fish darting in and out. This site is best for experienced divers comfortable with overhead environments.
