Which River Is Known As The Silent River Of India?

The Kunthipuzha River is famously known as the Silent River of India. It flows through the heart of the Silent Valley National Park in Kerala. The river got this name because the forest it flows through is so dense that even the chirping of cicadas is often absent, making the area unusually quiet.
Source and Path
The river begins its journey in the high hills of the Nilgiris, at an altitude of about 2,000 metres. From there, it flows entirely through the state of Kerala.
Unlike many other rivers that pass through towns and cities, the Kunthipuzha flows almost entirely through thick, protected evergreen forests. This keeps its water crystal clear and free from pollution.
Where it Empties
After travelling through the Silent Valley, the Kunthipuzha joins the Thoothapuzha River. Eventually, these waters merge with the Bharathapuzha, which is the second-longest river in Kerala. From there, the water finally empties into the Arabian Sea.
