Brunei’s waterways thread through coastal lowlands, peat swamps and small towns, shaping travel, livelihoods and local ecosystems. Whether viewed from a boat or a roadside bridge, the rivers are an easy way to read the country’s geography and communities.
There are 9 Rivers in Brunei, ranging from Anduki River to Tutong River; each entry is presented with District,Length (km),Notable so you can compare location, size and key features — you’ll find below.
How can I tell which rivers are the longest and where they flow?
Use the Length (km) column in the list to identify the longest rivers and the District column to see where they run; the Notable column highlights navigation, settlements or protected areas. Keep in mind measurements can vary by source, so consult recent maps or local records for precise figures.
Are these rivers accessible to visitors and what should I prepare?
Many rivers have public access along roads or at boat launches, but upstream or protected stretches may need permission or guided visits; bring insect repellent, respect local communities and mangroves, and check weather and tide conditions before planning any river trip.
