Mannavanur Lake is a high-altitude water body situated in a scenic valley within the Dindigul district of Tamil Nadu. It is located roughly 35 kilometers from the popular hill station of Kodaikanal. The lake is part of an eco-tourism project managed by the forest department, emphasizing conservation and sustainable visitation. The surrounding landscape features rolling hills, pine forests, and terraced vegetable farms typical of the Palani Hills. Visitors can engage in activities such as coracle rides and horse riding provided by local operators. The area serves as a habitat for diverse avian species and is frequently visited by migrating waterfowl. The lake maintains a consistent water level throughout the year due to the surrounding catchment area.
