Sarawak is one of two Malaysian states on the island of Borneo. Known as Bumi Kenyalang, it is situated on the north-west of the island. It is the largest state in Malaysia; the second largest, Sabah, lies to the northeast.Sarawak/serawak 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.

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 Malaysia.
The major rivers from the south to the north include 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.
