Arno Atoll is a stunningly complex coral system in the Marshall Islands, situated just 15 kilometers east of the capital, Majuro. It is unique for its structure, comprising 133 individual islets that encircle three distinct lagoons: a central lagoon of extraordinary depth and two smaller secondary lagoons. Despite having a total land area of only 13 square kilometers, the atoll spans a vast maritime territory. Arno is celebrated throughout the Pacific for its bountiful fishing grounds, which serve as a primary food source for both locals and the nearby capital. The residents are also famous for their exceptional weaving skills, producing some of the finest traditional handicrafts in the islands, including the renowned Kili bags. Life on Arno moves at a traditional pace, centered around copra production and ocean harvesting. Its pristine coral reefs and crystal-clear waters make it a paradise for divers and snorkelers seeking to explore untouched marine ecosystems away from the urban bustle of Majuro.
