At a distance of around 2 Kms from Idukki Bus Station, Idukki Arch Dam is the world's second and Asia's first arch dam, constructed on Periyar river across the Kuravan and Kurathi hills.
The 550 feet high and 650 feet wide dam lies close to the Cheruthoni Barrage. According to the legend, two natives were cursed by Lord Rama when he caught them staring at bathing Sita. The two natives, Koravan and Kurathi who were converted into stones (on opposite banks of Periyar river) begged Lord Rama for mercy since they had never stayed separate. Lord Rama blessed them that they will stay together for years to come. And, today, the Idukki Arch Dam links the two hillocks, Koravan Mala and Kurathi Mala. The Underground Power House is located at Moolamattom, 43 Kms from Idukki Dam.
The Reservoir is formed by three dams, namely, Idukki, Cheruthoni and Kulamavu. Boating facility is available in the reservoir.
Idukki is connected by frequent bus service from Munnar.
