About Snake Hole
Snake Hole is a shallow Irabu cave dive with an air dome and a wave-sensitive interior. Certified divers enter through a submerged opening and move up into a chamber where outside wave pressure can make the dome fog up. The appeal is the topography and light, not big-school action, and the site is best when the sea is calm. It is a guided cave dive rather than a casual snorkel stop.
