Borneo is the third largest non-continental island in the world (after Greenland and New Guinea). The island is located in Southeast Asia, straddling the equator. It's sparsely populated and famous for ancient rainforests filled with wildlife, including several primates and various rare and endangered species. The island also has extensive caves and rivers. In Indonesian, the term Kalimantan is used to refer to the entire island of Borneo, not just the Indonesian-controlled part as in Malay and English.
It is divided into three parts, administered by separate countries:
a tiny oil-rich monarchy occupying two small portions of the northwestern coast
|East Malaysia (Sabah and Sarawak)
the Malaysian part, occupying the northern third of the island
|Kalimantan (Central, East, South and West)
the Indonesian part, occupying the central and southern regions
The island's main airports by passenger traffic are Pontianak (PNK IATA), Banjarbaru (BDJ IATA), and Balikpapan (BPN IATA) in Indonesia and Kota Kinabalu (BKI IATA) and Kuching (KCH IATA) in Malaysia.
