With over 60 wrecks, many only recently discovered, Chuuk Lagoon is rich in history and in scare factor! According to Blue Lagoon Diving Resort, Chuuk was put in the middle of WWII when a naval-and-air attack between Japan and the U.S. hit in 1944. The attack lasted three days and the lagoon gained dozens of sunken warships. Being the largest known maritime war graveyard in the world, adrenaline-seeking divers have sensed the presence of those who lost their lives, and have claimed to hear sounds of running tank engines.

The S.S. Thistlegorm was the victim of a bombing that was not planned for it. In 1941, two German bombers were returning from a failed mission, looking for a place to get rid of their bomb-load — the S.S. Thistlegorm was in the wrong place at the wrong time. Ten minutes later, the ship exploded and sank to 115 feet. The wreck is still in good condition over 70 years later, and has remains of supplies meant for the British Navy. Brave divers report seeing shadowy figures above the wrecks and hearing machinery running.

The Hilma Hooker has quite a past that includes run-ins with the law and missing bodies. According to The National Underwater and Marine Agency, the Hilma Hooker was wanted by the FBI for drug-related charges in 1983, and was later found with 25,000 pounds of marijuana stowed in false compartments. The owners of the ship were never found, and the Hilma Hooker was sunk purposely in 1984. The wreck remains a popular attraction in Bonaire, and is bursting with marine life.
