The site’s main attraction is a trio of striking lava tubes that tunnel toward the Sheraton Kauai Hotel’s house beach. Divers kick through these massive structures, with communities of reef crabs, spiny lobsters and shrimp scampering between the nooks to crannies. Remember to crane your neck to the tubes’ lava ceilings: you’re sure to spot some crustaceans and turkeyfish dangling from the cracks.
