Because of the location of Andorra in the eastern Pyrenees mountain range the principality consists predominantly of rugged mountains, the highest being the Coma Pedrosa at 2,942 metres (9,652 ft), and the average elevation of Andorra is 1,996 metres (6,549 ft). These are seperated by three narrow valleys in a Y shape that combine into one as the main stream, the Gran Valira river, leaves the country for Spain (at Andorra's lowest point of 840 m/2,756 ft). Andorra's land area is 468 km² (181 sq mi).
