River Cruising
'Sungai' is the Malaysian word for river. In Malaysia, there are many rivers and mangrove areas where wildlife viewing is possible from the water. Riverine and mangrove habitats are home to large amounts of indigenous flora and fauna; and by nature many animals are drawn to water sources for drinking and cooling.

Cruises can be early in the day, mid-evening or night depending on the type of fauna targeted for viewing. Among various established sites for tree-and-mangrove cruising, Sungai Kilim on Langkawi Island is recommended where tree crabs, iguanas and macaques can been observed. A thrilling highlight is experiencing the eagles that swoop down on the feed thrown into the water. Sungai Selangor, just two hours from Kuala Lumpur, is famous for its firefly colonies that flicker together like festival lights. Similar fireflies cruise is available in the Santubong area in Sarawak, Garama Wetland in Sabah and Kampung Ibok in Terengganu.

 
Practical River Cruising Tips
Bring along sun cream or a brimmed hat against the sun or in case shade trees are few.
Binoculars are most handy and zoom cameras will afford the sharpest photos.
Insect repellant is useful for evening and night tours.
Hiring a knowledgeable guide will increase your chances of seeing what the lesser trained eye might miss, since tropical animals are master at camouflage.
Cruises at estuaries or coasts depend on the tides. Check with the operator for exact departure time for your preferred cruise.
 
Cruises are rarely done in the heat of mid-day, as it gets too hot for both human and other wildlife.
