Sarawak Geography

Having land area of 124,450 km² spreading between latitude 0° 50′ and 5°N and longitude 109° 36′ and 115° 40′ E, it makes up 37.5% of the land of Malaysia. Sarawak also contains large tracts of tropical rain forest home to an abundance of plant and animal species.

Sarawak is currently divided into eleven Administrative Divisions: Kuching Division, Samarahan Division, Sri Aman Division, Betong Division, Sarikei Division, Sibu Division, Mukah Division, Kapit Division, Bintulu Division, Miri Division and Limbang Division.

The country stretches for some 750 km along the north east coastline of Borneo interrupted in the north by about 150 km of Brunei coast (not adding the coastline along the bays). Sarawak is separated from the Indonesian part of Borneo, Kalimantan, by ranges of high hills and mountains that are part of the central mountain range of Borneo. These get higher to the north and culminate near the source of the Baram River with the steep Mount Batu Lawi, Mount Mulu in the Park of the same name and Mount Murud with the highest peak in Sarawak.

The most important rivers are from the south to the north the Sarawak River, the Lupar River, the Saribas River, the Rajang River with 563 km the longest river in Malaysia with the Baleh River branch, the Baram River, the Limbang River that drains into the Brunei Bay as it divides the two parts of Brunei and the Trusan River that also flows into the Brunei Bay.

Sarawak can be divided into three natural regions. The coastal region is rather low lying flat country with large extents of swamps and other wet environments. The hill region provides most of the easily inhabited land. Most of the larger cities and towns have been built in this region. As the swamps make up much of the coast, the ports of Kuching and Sibu have been built some distance from the coast on rivers, while Bintulu and Miri are close to the coast at the only places that the hills stretch right to the China Sea. The third region is the mountain region along the border and with the Kelabit and Murut highlands in the north.
