Bikini Atoll
Marshall Islands
Atoll·Remote, Haunting, Pristine, Historical
Bikini Atoll is a complex of 23 islands in the Marshall Islands, famously used by the United States for nuclear testing between 1946 and 1958. Now a UNESCO World Heritage Site, the atoll remains largely uninhabited due to lingering radiation, though it has become a bucket-list destination for technical divers. The lagoon floor is home to a 'ghost fleet' of sunken warships, including the USS Saratoga, offering some of the most significant wreck diving on Earth. Beyond its somber history, the atoll is a fascinating enclave of nature where marine life has flourished in the absence of human settlement.
