Though a UNESCO World Heritage Site and often visited by tourists, Bikini Atoll is a highly dangerous place. It was the site of nuclear weapon testing between 1946 and 1958. Upon the declaration of reduced radiation levels, many returned in 1987, but it still wasn’t safe. Food and plants are still contaminated. Original inhabitants refuse to return, and eating the local produce is strongly discouraged.
