Geylang River is one of the 32 rivers in Singapore. The name is believed to be derived from the Malay word "kilang", which means factory or mill. A tributary of the Kallang River, the Geylang River flows into the Kallang Basin. Geylang River starts at Ubi, where it is no larger than a drain, and begins its journey southwards, gradually widening as it goes along. By the time it crosses Geylang Road near City Plaza, the river has widened substantially. It makes a couple of bends before ending its course at the Kallang Basin near the Singapore Indoor Stadium.
Today the areas on both sides of the Geylang River, over a stretch of 850 meters, have been turned into greens and parks for the recreational use of the locals.
