Ponnaiyar River, Sacred river between Nandi Hills and Bay of Bengal, India
The Ponnaiyar River flows from the hills of Karnataka into Tamil Nadu and receives water from several tributaries including the Chinnar, Markanda, and Vaniar. The river supplies water to farming areas across multiple districts and is controlled by dams at Krishnagiri and Sathanur.
The river rises in the southern mountains and has shaped kingdoms and villages across this region for centuries. Its waters have always been essential for farming and settlements throughout the area.
Local people consider the river sacred and gather along its banks during seasonal festivals to celebrate the water. Temples such as Penneswaraar sit on its shores, serving as places where visitors see religious life connected to the river.
You can explore the river at various points along its course, though dams and irrigation channels shape how it flows through the landscape. It helps to ask locally which access points are best and which areas are open for visiting.
The river splits into two outlet channels near its end, with one reaching the Bay of Bengal near Cuddalore and the other flowing toward Pondicherry. This division means the water flows in two directions and serves different coastal areas.
