Ant Atoll, also known as Ahnd Atoll, is a pristine marine sanctuary located approximately 18 kilometers west of Pohnpei. Designated as a UNESCO Biosphere Reserve in 2008, it stands as a testament to the incredible biodiversity of Micronesia. The atoll comprises 13 small, uninhabited islands encircling a deep, crystal-clear lagoon that supports a lively underwater world. Its remote and protected status makes it a vital nesting ground for green sea turtles and a sanctuary for various seabird species, including frigates and boobies. Below the surface, the coral reefs are remarkably healthy, featuring extensive colonies of stony and soft corals that provide habitat for over 130 fish species, sharks, and rays. The lack of permanent human settlement has allowed the natural ecosystem to thrive undisturbed, making Ant Atoll one of the most significant conservation sites in the Pacific. It remains a destination for eco-conscious travelers and scientists who seek to experience a truly untouched marine environment.

📋 Practical info
Best season
The best time for observing sea turtles and seabirds on Ant Atoll is typically from November to April, when the dry season brings calm weather. During these months turtle nesting is common on the beaches and seabird activity is at its peak.
Best time of day
Early morning hours are handy for watching seabirds take flight, while dusk often brings turtles ashore to nest. For nighttime egg-laying, late evening until midnight is the most promising time to observe.
Etiquette
Keep a minimum distance of at least 10 meters from turtles and seabirds to avoid disturbing them. Feeding or touching the animals is strictly prohibited, as is entering marked nesting areas.
What to bring
Bring binoculars and a camera with a telephoto lens for observing seabirds. Also pack sturdy footwear and a hat, as pathways on the island are often unpaved and sunny.
Getting there
Ant Atoll is accessible only by boat from Pohnpei, with the journey usually taking one to two hours. It is recommended to book a local tour operator who can provide permits and a guide.
