One of the most interesting places to see in Valparai is the Nirar Dam. It is situated 16 km from the hill station of Valparai and the entire region is well-connected through a good network of roads. There is another adjacent dam called the Lower Nirar Dam located inside the jungle.
The most thrilling and intriguing part is crossing the 8km long tunnel that connects the Nirar Dam with the Solaiyar Dam. The Nirar Dam was constructed mainly for irrigation purposes and to provide hydroelectricity to the area.
