The Big Island's volcanic underwater topography is a diver's wonderland. Lava tubes, bommies, arches and huge craters like "Au Au Crater," create a spectacular backdrop for Hawaii's many indigenous species of buttlerfly fish. Photographers will delight in the many patient subjects like Spanish Dancers, turtles, mantas and frogfish. The standard Kona Aggressor II scuba itinerary is Saturday-to-Saturday with five and one-half days of diving. Guests may board Saturday after 2:00 p.m. Dinner is served on board Saturday evening followed by the Captain's briefing. Friday afternoon, the Kona Aggressor II returns to Kailua-Kona Bay.
