Fiji's 332 islands are scattered over a vast area of the Pacific Ocean, some are 1,290,000 sq km in extent. Viti Levu, which is the main island of Fuji, is about 10,400 sq km in area, with high rainfall in the east and much lower rainfall in the west. The country’s first and third biggest cities respectively – Suva and Nadi – are located at opposite ends of Viti Levu, like sentinels guarding against enemy invasion – only these days, the invaders are friendly, coming as tourists rather than cannibal-warriors. Because of the consistently bad weather conditions, Fiji's main international airport was moved to Nadi in 1982. As a result, most of Fiji’s tourist development and facilities are concentrated around Nadi and the southern “Coral Coast” of Viti Levu. Nadi also makes a great base for exploring the Mamanuca and Yasawa island groups, the southern island of Kadavu, and the “garden island” of Taveuni, with easy access also to the laid-back port of Savusavu on Vanua Levu Island.
