Idukki Arch Dam

Idukki Arch Dam, an engineering marvel, is located in the South-Indian state of Kerala. It is an arch dam with a double curvature and is built on River Periyar. Precisely, the dam is constructed in a gorge between two hills, Kuravathi and Kuravan. It is at the height of about 550 feet and is a breathtaking sight in the otherwise rugged terrain along which has been built. With this height, it is one of the highest arch dams in Asia. Because of its massive size, the dam can be seen from quite some distance and the sight of the structure in between the granite hills is breathtaking. The surrounding is lush green, and the reservoir serves as a quick getaway for locals. As part of promoting hydel tourism, boating in the reservoir is open for tourists.

The Idukki Arch dam was built by the Kerala State Electricity Board under a project to produce hydro-electric power for regions nearby. This marvel attracts tourists from all over the world. It is one of the few double curvature parabolic thin arc dams in India. The reservoir is a splendid sight from atop Kalvary. If you manage to make some extra time for this visit do make sure you hike up Kalvary and witness the spectacular view. Just absorb the mesmerizing beauty site while you are there because photography is not allowed and you don't want to forget about this grand structure.

The forest area surrounding the dam and the reservoir is home to many local species. About a kilometre further away is a cave that became famous for being featured in a Malayalam Movie named Vyshali. It has been named Vyshali Cave ever since and often visited by the people coming here to see the dam.
