Idukki Arch Dam in Kerala has a height of 168 metres (550 feet) and is Asia’s tallest arch dam. It is constructed between two granite hills called Kuravanmala (839 metres) and Kurathimala (925 metres).
Idukki Dam is 54 km (2 hours 5 minutes) from Munnar. The route passes through Pallivasal, Chithirapuram, Anachal, Selliampara, Kallarkutty and Karimban. There is a dam at Kallarkutty which can be seen from the road. The route is scenic through mountain roads. The roads are good and there was not much of traffic.
Idukki Dam is open to the public only on weekends and on certain festival days. However Hill View Park, 1.5 km from Idukki town, offers panoramic views of Cheruthoni as well as Idukki dams. The park is on top of a hill at a height of 350 feet. It is open on all days, from 9:00 am to 5:00 pm. There is an entry fee of Rs 10 per adult and Rs 5 per child.
At the base of Hill View Park is a travellers bungalow operated by KTDC. A large parking area has been provided. Vehicles are not allowed beyond the parking area. Visitors must walk up the road to top of the hill. The climb takes up 15-20 minutes.
The panoramic view from the top is spectacular. Idukki Dam is opposite the view point while Cheruthoni Dam is to the left. Kulamavu Dam is also in the vicinity but cannot be viewed from the park. Idukki, Cheruthoni and Kulamavu dams have created the huge reservoir. The water is carried by underground pipes to Moolamattam Power Station. It is the biggest underground hydro-electric power station in India.
Water in the reservoir is spread over a large area. If you are lucky, you may be able to see herds of elephants, bison, deer and other wild animals in the forested hills below.
Hill View Park is spread over 8 acres and is well maintained. There is a snack bar and wash room for the visitors. From Idukki, Thekkady is 58 km (1 hour 45 minutes). The road passes through Narakakkanam, Kattappana and Anakkara.
