Iddukki dam

It's one of the most beautiful dam, designed in such a way that your eyes will have a multiple orgasms. Sometimes you feel jealous about local people of Munnar for obvious reasons. The only sad part was that the cameras and Mobile phones were not allowed, the security arrangements were very strict.

Amazing architechture

Located in the lively and beautiful hills of Idukki is lovely yet magnificent creation of man to regulate the water resource of nature. The architecture is mind boggling and the access is very easy. Best place to teach children about water resources, conservation, hydral electricity.

Dam in between Two Hills

The Asia's one of the best Arch Dam built by connecting two hills namely Kuravan and Kurathi. Near by this Dam there is an adjacent Dam called Cheruthoni. A small Entrance fee is there for visitors but not allowing Mobile phone, Camera etc. Very strict and tight security is there by forest and Dam authorities. Very beautiful locality and every where surrounded by hills. They are providing a battery run vehicle for non-walkers. But we 7 member team, even though we covered 60 years of age decided to walk up to the end of the Arch Dam from Cheruthoni entrance. It will take 2 hours to cover more than 3 km by foot. After enjoying the scenario of that location. Water is in the Dam which is not upto the mark because of the season. But the journey is through forest.The construction is very fine. When this arch Dam covered by water the Cheruthoni Dam shutter will open to manage the water flow.

Keralas own pride

Idukki Arch Dam is one of Kerala's best attraction, we can go by our own vehicle upto the entrance. Phones, camera, matches and lighters are not allowed inside the dam, it's about 3 km to walk from the entrance to arch dam through cheruthoni dam. One can also visit vaishali cave which is on between two dams. The dam is constructed between two Hills kuravan and kurathi Malai. Cabs are available for people who have difficultly to walk and cafeteria is also present on two ends.

Biggest Arch Dam in India

Awesome ambiance with nice climate. The cool breeze makes the feel double. If the climate is ok, they do have boating facility too which add on to this. People who love to walk will love more as we can walk from one to another around 30mnts. But the dam is open for public during public holidays only.

Extraordinary visit and view

It was one of the best experience of my life, Idukki Arch Dam is the second biggest arch dam in Asia and it is worth. The entry is from Cheruthoni Dam from we have to park our car and enter by a small fee, you cannot carry mobiles, cameras or even a lighter, there are huge safety measures. First we go on through Cheruthoni Dam which is ok then it's a long walk of 3. 75 to the arch dam. It's fun, after the walk we reach on top of the arch dam it's a beautiful view, there are some caves too. There is one cart which services through, we started walking back and reached half journey and from there we saw a road to the top. Nobody was taking that way so we simply decided to go through and we walked and reached the top and then only understood that was the huge cave which is known as Vaishali cave popular in the movies Vaishali and Idukki gold and we stepped in its 75 meter long. We stepped and it was dark and light at the end, we started walking when suddenly bats started moving around there were like 1000s of bats we became scared and was standing with second thoughts and we decided whatever lets do it and we walked pretty slowly and reached the end. I promise you one of best views ever, I loved it and it was one of the best experience of life :) Idukki Arch Dam opens only on public holidays and its a must visit.

Huge and magnificient

We visited on 22nd Oct, that is Dusshera. This dam is open only on Kerala public holidays. We were lucky to visit on one of such public holidays. The entry to the Dam is from Cheruthoni Dam which is exactly 7 Kms from the Idukki Dam entrance. Both the Dams were lovely. We took Baggi Ride which is an electric vehicle and starts from Cheruthoni and ends at Idukki Dam. The distance of the ride is 2. 5 kms. Idukki Dam is the largest arch Dam of Asia and a must visit place in case you are in Kerala. We thoroughly enjoyed this place. While coming back from Idukki Dam we came walking till Cheruthoni. Looking at the Dams you will be amazed as both of them are huge and you will really feel proud to watch these wonders

The Anchuruli Lake, Kalyanathandu Hills, the beautiful Idukki Reserve and associated forests. Now it's open not only during on am but also throughout the year.

The highest Arch Dam in Asia

The dam built on the Periyar River between the two mountains - Kuravan and Kurathi Malas for hydroelectric power generation is believed to be highest Arch dam in Asia. This dam constructed with Canadian aid along with two other dams at Cheruthoni and Kulamavu shares a common reservoir. The Water from the reservoir is brought down through a tunnel to Moolamattom Power station for power generationThough the public entry into the dam was banned due to security reasons, it was relaxed for one month during the Onam and the Christmas seasons. The dam can be seen from most of the places in Idukki and the vast reservoir with the other two dams, the Kuravan and Kurathi mountains, the crisscross roads connecting the small townships, the fresh and cool air are real fascination in the area which we enjoy.

Need special permission to visit

An engineering marvel, the location is good and a must see spot for travellers who visit Idukki. You may need a pass to visit some of the places and need special permission to go near the dam. There are tunnels inside the dam but entry are restricted.
