Fiji consists of 322 islands (of which 106 are inhabited) and 522 smaller islets. The two most important islands are Viti Levu and Vanua Levu. The islands are mountainous, with peaks up to 1,300 metres (4,250 ft), and covered with thick tropical forests. Viti Levu hosts the capital city of Suva, and is home to nearly three quarters of the population. Other important towns include Nadi (the location of the international airport), and the second city - Lautoka (the location of a large sugar mill and a seaport).The main towns on Vanua Levu are Labasa and Savusavu. Other islands and island groups include Taveuni and Kadavu (the third and fourth largest islands respectively), the Mamanuca Group (just outside Nadi) and Yasawa Group, which are popular tourist destinations, the Lomaiviti Group, outside of Suva, and the remote Lau Group. Rotuma, some 500 kilometres (310 mi) north of the archipelago, has a special administrative status in Fiji. Fiji's nearest neighbour is Tonga.
