A parabolic marvel, aloft at 550 ft and spread out over 650 ft, greets visitors at the Kuravan and Kurathi Hills in Idukki. You have now reached the Idukki Arch Dam, the second in the world and first of its kind in all of Asia. The sight itself is awe-inspiring, considering the sheer magnitude of the structure and the purpose it serves. Nearby lies the Idukki Wildlife Sanctuary where one can seek solace in nature.
