Siruvani Waterfalls, Waterfall in Coimbatore district, India

Siruvani Waterfalls is a waterfall in Coimbatore district of Tamil Nadu near the border with Kerala, dropping roughly 150 feet (45 meters) over rocky terrain. The water collects in a natural basin surrounded by dense tropical forest and green slopes of the Western Ghats.

The area gained importance from 1927 when construction of a dam downstream began to harness the sweet water for the city of Coimbatore. The project was completed several decades later in the 1980s, changing access to the source.

The falls are also called Kovai Kutralam, and the dam road's gateways carry Kerala and Tamil architectural styles side by side. Mudugar and Irula communities live in these hills, and forest guards still accompany visitors to the dam, a practice dating from its construction.

Access is via the Sadivayal checkpost, where private vehicles stop; the forest department then shuttles visitors to the trailhead. From there a walk of nearly 1 km through forest leads to the bathing area by the fall. Forest guards accompany visitors to the dam. Entry to the protected forest is not allowed at night.

The water from this source is regarded as one of the purest and tastiest in all of India, which is why it has long been used for drinking water supply. Locals swear by its natural sweet taste that can be noticed without any treatment.
