Ontong Java Atoll, also known as Lord Howe Atoll, is one of the largest coral atolls on Earth, located in the far north of the Solomon Islands. It consists of approximately 120 small islets surrounding a massive central lagoon covering about 1,400 square kilometers. Geographically, it is classified as a Polynesian Outlier, as its inhabitants are culturally and linguistically more closely related to Polynesians than to the Melanesian majority of the country. The maximum elevation of the islands is only a few meters above sea level, making the atoll extremely vulnerable to sea-level rise and storm surges. Economically, the population depends almost entirely on marine resources and the production of copra and sea cucumbers (beche-de-mer). Its remote location has helped preserve traditional ways of life and social structures to this day.

📋 Practical info
Best season
The best time to explore Ontong Java Atoll is during the dry season roughly from May to October. Then winds are weaker and the lagoon water is especially clear and calm.
Best time of day
Early morning hours see the most bird activity on the islands while reef dwellers start foraging in the water. At dusk the chance of spotting sea turtles also increases.
Etiquette
Do not walk on reef platforms at low tide to avoid crushing delicate corals. Do not feed fish or collect shells or corals in order to protect the fragile ecosystem.
What to bring
A good snorkeling set with mask, snorkel and fins is essential for exploring the lagoon. Neoprene shoes protect your feet from sharp corals and rocks.
Getting there
The atoll is reachable only by boat or small aircraft, with regular connections from Honiara. On site motorboats are available for trips to the various motus.
What to expect
Because the lagoon is very extensive, it may take a while to find the best fish schools or turtles. Plan multiple days to experience the full biodiversity.
