Makaha Caverns is a West Oahu gem. The dive site is actually a series of interconnected lava tubes that hold fun swim-throughs in shallow water with lots of light. This dive is a great way to experience an amazing natural phenomenon that is rarely seen by other people. Inside the various swim throughs divers will encounter schools of soldier fish, trumpet fish, and the occasional sleeping sea turtle. This dive is usually paired with the Mahi shipwreck dive.
