Idukki Arch Dam – Kerala’s Monument of Engineering and Majesty
Nestled between the towering Kuravan and Kurathi hills, the Idukki Arch Dam stands as one of India’s greatest engineering marvels and a symbol of Kerala’s ingenuity. Soaring 550 feet high and curving gracefully across the Periyar River, it is among the tallest arch dams in Asia — a breathtaking fusion of human achievement and natural grandeur.
The setting is spectacular. Surrounded by verdant hills and a vast expanse of shimmering water, the dam forms part of a three-dam system along with Cheruthoni and Kulamavu, together creating the immense Idukki Reservoir. The calm waters mirror the surrounding peaks, offering striking photo opportunities and a serene escape for visitors seeking both beauty and perspective.
Informative displays along the viewing area share fascinating insights into the dam’s construction, hydroelectric system, and its role in powering much of Kerala. While access to certain areas is restricted for safety reasons, designated viewpoints provide panoramic vistas that make the journey well worth it.
Located around 60 km from Blanket Days Resort & Spa, Thekkady, it’s a scenic drive through winding mountain roads, often paired with visits to Moolamattom Power Station or nearby hill attractions.
Travel Tips:
Visit during the dry months for clear skies and unobstructed views.
