Coron Bay is famous for the wrecks of a Japanese supply fleet sunk by U.S. Navy war planes in September 1944. Most of the wrecks are deep enough to require Nitrox to maximize dive time. The wrecks were stripped by the local population many years ago. I dove these wrecks in June of 2009. The visibility was poor (30 feet or less). Underwater photography both with and without a strobe was very difficult due to the amount of particulate matter in the water and the lack of ambient light at depth. Staying at a resort in Coron Town requires a 1.5 to 2 hour boat trip to and from the wrecks.
