Situated at 17.70° South and 178.8° East, (60 km north east from the national capital Suva and 20 km off the east coast of Viti Levu), the island is about 13 kilometers long and 10 kilometers wide. It covers a total area of 106.4 square kilometers and has a population of around 9,100, approximately half the Lomaiviti population. Levuka, Fiji's former capital, is the largest of 24 towns and villages on the island.
Ovalau is characterized by its rugged topography, with little flat land apart from the Lovoni Valley in the centre of the island. The island is an eroded volcanic crater with a narrow belt of flat to udulating country between the encircling lagoon and the steep crater sides. The highest peaks are Nadelaiovalau, with an altitude of 625 meters, in the east, and Tomuna, 526 meters, in the south.
