Easter Island is one of the world's most isolated inhabited islands.[1] Its closest inhabited neighbours are the Chilean Juan Fernandez Islands, 1,850 km (1,150 mi) to the east, with approximately 850 inhabitants.[citation needed] The nearest continental point lies in central Chile near Concepción, at 3,512 kilometres (2,182 mi). Easter Island's latitude is similar to that of Caldera, Chile, and it lies 3,510 km (2,180 mi) west of continental Chile at its nearest point (between Lota and Lebu in the Biobío Region). Isla Salas y Gómez, 415 km (258 mi) to the east, is closer but is uninhabited. The Tristan da Cunha archipelago in the southern Atlantic competes for the title of the most remote island, lying 2,430 km (1,510 mi) from Saint Helena island and 2,816 km (1,750 mi) from the South African coast.
The island is about 24.6 km (15.3 mi) long by 12.3 km (7.6 mi) at its widest point; its overall shape is triangular. It has an area of 163.6 km2 (63.2 sq mi), and a maximum elevation of 507 m (1,663 ft) above mean sea level. There are three Rano (freshwater crater lakes), at Rano Kau, Rano Raraku and Rano Aroi, near the summit of Terevaka, but no permanent streams or rivers.
