The Idukki dam is constructed across the Periyar River, in a valley between the Kuravan and Kurathi hills in Kerala. The awe-inspiring, majestic dam, which stands at 167.68 meters (550 ft), is one of the highest arch dams in Asia. The dam, which is one of the Idukki tourist places, constructed by the Kerala government in 1975 and supports 780 MW hydroelectric power station that draws electricity from this dam.
The sheer magnitude of the structure along with the mountains, verdant vegetation, and 60 sq. km placid lake, which is created by the 3 dams, Idukki dam, Cheruthoni and Kulamavu, captivate the visitors.
