Kuala Kampar
Kuala Kampar lies at the broad mouth of the Kampar River on Sumatra's eastern coast. Here river water meets the tides of the straits in a shallow estuary of branching channels and low, wet shores. A powerful tidal bore known as the Bono travels upstream when the incoming sea presses into the narrowing river. The wave can make navigation difficult, and its force has given rise to local stories of the “Seven Ghosts”.
