Bikini Atoll, in the remote Republic of the Marshall Islands in Micronesia, is probably the most famous place in the world for wreck diving. Not long after the second world war, the US gathered a mock fleet of naval vessels in order to test the different effects of atomic bombs on warships. 67 nuclear bombs were tested between 1946 and 1958, most notably during ''Operation Crossroads''. Visit the (in)famous lagoon and its wrecks on this Bikini Atoll 13 nights liveaboard diving itinerary aboard Truk Master and Pacific Master.
Maps & Itinerary
More than 75 years after Operation Crossroads began, the nuclear ghost fleet of Bikini Atoll (as these wrecks are known) rest in crystal blue waters that have since become home to an abundance of marine life with thriving reefs. Only since 1996 has Bikini Atoll been open to diving, making this destination a one-of-a-kind combination of spectacular historic wrecks in a remote and otherwise untouched tropical paradise. Nowhere else can you dive such a fantastic collection of wrecks, including battleships, submarines, destroyers, and most notably the aircraft carrier USS Saratoga.
As the wrecks of Bikini Atoll are only suited for extended range diving, there will be 2 technical dives offered per day. Divers will be responsible for planning their own dives, with the assistance of the Cruise Director who has dived the wrecks of Bikini many times already.
For safety, the minimum surface interval between dives is 4 hours and, it is mandatory to take an afternoon off from diving mid-trip; an optional land tour of Bikini Island and beach BBQ will be offered instead of diving.
Travel time between Ebeye Island and Bikini Atoll is 23-34 hours depending on conditions. On some trips, it may be possible to dive the Prinz Eugen wreck near Kwajalein, or the Airplane Graveyard before sailing overnight to Bikini Atoll.
Please note: We cannot support Trimix for open circuit divers on Bikini Atoll itineraries.
