Bikar Atoll represents one of the most pristine coral reef ecosystems remaining in the Pacific, situated in the remote northern reaches of the Ratak Chain. Uninhabited by humans, its isolation is reinforced by a hazardous reef structure that allows only limited access through narrow channels. Despite its small land area of just 0.5 square kilometers spread across six islets, Bikar is an ecological powerhouse. It serves as a primary regional nesting site for the endangered Green sea turtle, which relies on the undisturbed sandy beaches for reproduction. The interior of the islets is covered by native Pisonia grandis forests, providing vital nesting grounds for immense colonies of boobies, frigatebirds, and terns. The surrounding lagoon and coral gardens are equally rich in marine life, thriving in the absence of commercial fishing. Since the 1970s, Bikar has been at the forefront of conservation proposals, aimed at formalizing its status as a protected nature reserve to safeguard its unique biological heritage.

📋 Practical info

📅

Best season

The best time for birdwatching at Bikar Atoll is during the breeding season from May to August, when thousands of birds nest and rear their chicks. Green sea turtles are mainly seen on beaches from June to October when they lay their eggs.

🌅

Best time of day

Dusk is good as birds fly out in the morning and return to their nests in the evening. Turtles usually nest at night; if you come to the beach during the day, look for fresh tracks in the sand.

📜

Etiquette

Keep a minimum distance of 30 meters from nesting birds and turtles to avoid disturbance. Do not use artificial light at night as it can disorient turtles, and take all rubbish away with you.

🎒

What to bring

Binoculars with at least 8x magnification are essential for birdwatching. A waterproof flashlight with a red light allows you to see turtles at night without blinding them.

🧭

Getting there

Bikar Atoll is remote and can only be reached by chartered boat from Majuro or another inhabited atoll. The crossing may take several days depending on weather and vessel; an experienced crew is needed.

🦌

What to expect

Wildlife watching on an uninhabited atoll requires patience - birds come and go on their own schedule. Plan for several days and bring ample supplies as there are no facilities.
