Oh- I meant to add, in addition to the great vis- there are fabulous reefs and some really cool wrecks, inlcuding Japanese seaplanes, a Zero, the Tokia Maru/ Cormoran wreck (a WWI German vessel and a WWII Japanese vessel which actually lay partially on top of each other), the Kitsugawa Maru (another Japanese vessel vintage WWII), the "Seabee Junkyard" which is a treasure trove of WWII "stuff". Apra Harbor is full of 1940's (and older) glass bottles (mostly Coke and Pepsi) and other stuff like that. Gab Gab Beach has the best reefs, and the old Japanese Fuel Piers are also a good place to hunt for "artifacts". There is also an old seaplane ramp that was once a stop ont he China Clipper run that has some good stuff too.
