Marshall Islands

A coral atoll of 133 islands in the Ratak Chain, 20 kilometres east of Majuro, enclosing three separate lagoons instead of one. It is the closest atoll to Majuro and offers a quieter alternative for visitors seeking an authentic, low-key atoll experience without development pressure.

A coral atoll in the northern Ralik Chain, chosen by the United States for 23 nuclear weapon tests between 1946 and 1958. The islanders were forcibly relocated and have never returned; the atoll remains radiologically closed to habitation but is a bucket-list destination for technical divers.

The largest atoll in the world by lagoon area, part of the Ralik Chain. Kwajalein Island is a United States Army missile test range and the economic hub of the Marshall Islands through the annual rent paid by the US for the base.

The capital and largest city of the Marshall Islands, a long narrow atoll housing roughly half the country's population. It is the political, commercial and transport hub of the country, with a lagoon-side roadway, government offices and the country's only significant tourist accommodation.

A coral atoll of 71 islands in the Ratak Chain, with a land area of 9.8 square kilometres and a lagoon of approximately 95 square kilometres. The atoll is notable for the extensive Second World War wreckage of a Japanese naval base on Tōrakku Island, where concrete bunkers, runways and shipwrecks form one of the best-preserved WWII archaeological landscapes in the Pacific.

A small coral atoll of 13 islands in the Ralik Chain, one of the most remote and least-visited in the Marshall Islands. Its lagoon of nearly 95 square kilometres is largely unexplored by recreational divers, and the surrounding ocean margin is considered a high-quality dive site with minimal human impact.
