How an ox-bow forms
A lowland river as flat as the lower Kinabatangan swings in huge meanders; floods eventually punch through a meander's neck, the river takes the shortcut, and silt seals the abandoned bend into a crescent lake. In flood season the river reconnects and restocks them with fish — which is why the lakes concentrate herons, egrets, darters and kingfishers, and why proboscis troops favor their quiet margins.
Visiting one
Lake visits slot between cruises: a boardwalk or small-boat entry, still black water, and a different, hushed register from the main river. The RM1,920 3D2N pairs an ox-bow with Gomantong and the Menanggul — the widest habitat sample any three-day itinerary offers. Wet-season high water opens boat access to lakes unreachable in the dry.
Frequently asked questions
What is an ox-bow lake?
A crescent lake formed when a river cuts through the neck of a meander and abandons the old bend — the lower Kinabatangan has around twenty.
Which tours visit an ox-bow lake?
The 3D2N Sepilok/Sukau/Ox-bow/Gomantong (RM1,920) includes one, and the Tanini 3D2N (from RM880–1,080) includes an ox-bow lake walk.
What wildlife lives at the lakes?
Fish-hunting birds — herons, egrets, darters, storks, kingfishers — plus proboscis monkeys and macaques along the quiet margins.
