Two main tributaries, the Galas and Lebir Rivers converge into a single flow marking the beginning of Kelantan River. The Kelantan Rover itself has few noteworthy tributaries, as it traverses through its flood plains. The Galas and Lebir however, have many tributaries feeding into them, which contribute to much of the volume of flow in the Kelantan River. Among them are the Pergau River, where a dam is being built, and the rivers Neggiri, Chiku, Aring and Pertang.

Many of these tributaries originate in the forested mountains where many Orang Asli tribes live. Lower down along the river, Malay villages dot the river banks as it passes through some of the most densely populated flood plains on the Peninsular.

Apart from these countless villages, four major towns are located near the river – Kota Bharu, Pasir Mas, Tumpat, and Kuala Krai. There are several islands in the river in particular near the estuary. The area around its eastuary, known as Kuala Besar, is dotted with picturesque fishing villages, which are also well-known for the housing the small industry craft of batik-making, a local hand-dyed cloth for which the Sate of Kelantan is famous.

The Kelantan River regularly overspills its bank during the months of November to February during the northeast monsoon season. To warn those living near the river of its rise, there is a monitoring station called the Bradley Steps at Kuala Krai near the confluence of the Lebir and Galas Rivers.

Kota Bharu town lays right by the Kelantan River, just a few kilometres before it reaches Kuala Besar estuary in the north. For more information, please contact the Kota Bharu Tourist Information Centre at 609-7485534.
