This is a boat dive around the corner from the Hanauma Bay. (normally leaving from Koko Marina) The water here here is normally very ruff. Makes it a little difficult to gear up. But well worth the trouble. Directly in front of the cave the water is about 50ft., but drops down to 90’+ farther out. Inside the cave the is bright, the center on the cave has a very large natural skylight. (much darker on the edges) Inside the cave you can find turtles, whitetip reef sharks and lots of small fishes. A very cool dive! If the water is real ruff, you can hear it crashing and it sounds like thunder.
