Maniniholo Dry Cave
Maniniholo Dry Cave (Maniniholo means "swimming Manini fish") is about 300 yards deep, and reaches to a small exit hole on the side of the mountain. The cave interior used to be larger than now, before a 1957 tsunami half-filled it with sand. To get there, go to Ha'ena Beach Park on Route 560. Look for the cave on your left.
