East Rennell, Vanuatu
This site is located in the southeastern Solomon Islands in western Vanuatu. It covers an area of 370 km2 and takes up 1/3 of the land area of Rennell Island. It is the world’s largest coral atoll with a length of 86 km and a width of 15 km. The site extends into the ocean approximately 3 nautical miles from the coast. Lake Tegano is a major attraction in the island area. Its predecessor was a lagoon in the atoll, and it is the largest high-salinity lake (155 km2) in the Pacific Islands region. The lake is divided into numerous steep limestone islands with rich endemic species.
