Namu Atoll is a remarkable coral formation in the Ralik Chain of the Marshall Islands, consisting of 54 distinct islets surrounding a massive 397-square-kilometer lagoon. The atoll's geography is defined by several deep-water passes that connect the tranquil interior waters with the powerful Pacific Ocean, creating a nutrient-rich environment for spectacular coral reefs. This marine biodiversity makes Namu a vital habitat for various species of sharks, rays, and sea turtles. The local population is primarily concentrated on a few larger islets, where copra production serves as the main economic activity alongside artisanal fishing. Namu has a storied history of traditional Marshallese voyaging, with the lagoon serving as a training ground for master navigators who used wave patterns and stars to cross the vast ocean. The remote nature of the atoll has preserved its pristine environment, offering a glimpse into the traditional Micronesian way of life. Today, Namu remains a sanctuary for Pacific wildlife and a testament to the resilience of island cultures living in harmony with the sea.

Etiquette
Only dive with an experienced guide who knows the local currents. Do not damage corals or collect souvenirs - the passes are fragile ecosystems.
