When the War Department undertook a series of aboveground nuclear tests at the end of World War II, they inadvertently created one of the world's finest wreck diving venues. Fifty years after a pair of atomic bombs were exploded over a fleet of warships anchored in Bikini Lagoon, civilians are once more allowed to visit this long-forbidden site. Located in a remote corner of the Marshall Islands archipelago, Bikini is a gigantic atoll, with small palm-studded islands surrounding a sand-bottom lagoon. On the bottom of this lagoon, in 180 feet of clear water, lie the remnants of the fleet sunk by the world's 4th and 5th atomic bomb. This fleet includes the Japanese flagship Nagato and the US carrier Saratoga, which sits intact and upright. Travel to Bikini is typically a multi-day event, and facilities on the island are basic but clean. Because the majority of wrecks lie below 130 feet, Bikini is a destination for advanced or technical divers. Within these circles, it is considered one of the ultimate dive experiences of one's career.
