Borneo is the third largest non-continental island in the world (after Greenland and New Guinea). It is located in Southeast Asia and is divided into three parts, administered by separate countries: Brunei, a sovereign country occupying two small portions of the northwestern coast, East Malaysia (Sabah, Sarawak), the Malaysian part, occupying the northern third of the island, and Kalimantan (Central, East, South, West), the Indonesian part, occupying the central and southern regions. Covered in impenetrable jungle where headhunters roam (on GSM networks, if nothing else), East Malaysia is rich in natural resources but very much Malaysia's hinterland for industry and tourism. Kota Kinabalu is the main hub of the region, fielding an increasing number of international flights as well. Kuching also has a large number of mostly domestic flights, but there are services to Miri, Labuan and Tawau. There are two states Sarawak with their own border control. Sarawak, the western part of Borneo, and Sabah on the Northeastern part. Sarawak has two major destinations for tourists: Bako National Park, with mangroves and many indigenous animals such as proboscis and silverleaf monkeyes, and the limestone caves in Mulu region. A visit to a longhouse a native tribe settlement can be an interesting adventure. Sabah is renown for its beautiful coral islands Mabul and Sipadan, as well as the highest mountain in Malaysia, Kota Kinabulu.
