High Quality Content by WIKIPEDIA articles! Lakeba (pronounced ) is an island in Fiji`s Southern Lau Archipelago; the provincial capital of Lau is located here. The island is the tenth largest in Fiji, with a land area of nearly 60 square kilometers. It is fertile and well watered, and encircled by a 29-kilometer road. Its closest neighbors are Aiwa 12 km to the southeast and Nayau 28 km to the northwest. Separated by deep sea from the latter but only by shallow waters from the former, when sea levels were lower during glacial episodes Lakeba and Aiwa formed one large island.
