Ponmudi Dam in Idukki District is constructed across the Panniar River, a tributary of the Periyar. Built in 1963, it has a length of 294 m. The dam is about 15 km from Adimali, on the way to Rajakkad.
Surrounded by forests and green lands, Ponmudi Dam is ideal for holidaying. With a picturesque view of the Western Ghats, trekking in the Panniar River is a bit adventurous. Fishing can also be enjoyed. The old bridge, Thookkupalm, built by the British is a unique attraction. Ruins of some ancient buildings are also found nearby.
Vellathooval Power House, Kallarkutty Dam, Kuthumkal Waterfalls and Sengulam Dam are some of the nearby attractions. Frequent buses are available from Adimali and Rajakkad.
