6Bikini Atoll, Marshall Islands

Bikini Atoll, part of the Marshall Islands, is a UNESCO World Heritage site and a popular destination for technical divers seeking to explore its numerous shipwrecks. However, this site is also one of the most dangerous dive spots in the world due to its history as a nuclear testing ground. Between 1946 and 1958, the United States conducted numerous atomic bomb tests at Bikini Atoll, leaving behind a graveyard of sunken ships and elevated levels of radiation.

The shipwrecks at Bikini Atoll, including the famous USS Saratoga aircraft carrier, rest at significant depths, requiring advanced technical diving skills and equipment. The deep dives and strong currents add to the challenges, and divers must be mindful of the potential long-term effects of radiation exposure.
