Welcome to one of Kerala’s most jaw-dropping landmarks! The Idukki Dam isn’t just a massive wall of concrete – it’s a place where nature and engineering meet in the most beautiful way. If you're planning to explore Idukki, this dam deserves a top spot on your list.
Built in the 1970s, the Idukki Dam was a visionary project that brought electricity to thousands of homes across Kerala. What makes it extra special? It was created with the help of Canada, using technology that was super advanced for its time.
The dam is part of the Idukki Hydroelectric Project, one of the biggest of its kind in India. It changed the game for Kerala’s energy production and made Idukki famous beyond its borders.
Here’s a cool fact: the Idukki Dam is one of only a few arch dams in all of Asia. Instead of a flat wall, it's curved like a rainbow between two giant hills named Kuravan and Kurathi.
This arch shape is not just pretty – it's powerful. It pushes the water’s pressure into the mountains, making the dam super strong with less concrete. Smart and stunning!
It’s also the highest arch dam in India, standing tall at 168.91 meters. That’s taller than a 50-story building!
Did you know there’s a tunnel inside the Idukki Dam? During special visiting days or government-approved tours, travelers can walk through parts of the tunnel used for hydroelectric systems.
It feels like stepping into a sci-fi movie – dim lights, echoing footsteps, and massive steel valves humming with energy.
While you may not always get access to the tunnel, the surrounding area and viewpoints give you a great peek into the dam’s inner workings.
This is one of the most asked questions online, so let’s clear it up: the Idukki Dam is built across the Periyar River – the longest river in Kerala.
The dam actually connects two hills and traps water from the Periyar, creating a beautiful manmade lake that powers thousands of homes with clean energy.
