One of the top ten embankment dams in the world, the Parambikulam dam is a great place to visit. It serves the irrigation needs of both states of Tamil Nadu and Kerala. Surrounded by emerald green hills and placid water, the reservoir provides an exquisite view for the tourists. It is the perfect spot for picnicking. As it is close to the tiger reserve, most tourists visit the place on the Parambikulam tour.
