The star-shaped artificial lake, with a depth of 3 meters, was built in 1863 under the stewardship of the Collector of Madurai, Sir Vere Henry Levinge. Known as the heart of Kodaikanal, this lake has been a much sought-after location for Bollywood movies. It is an ideal place for you to unwind and get rejuvenated. People can enjoy boating in the lake, either in normal or luxury boats. There are also rowing and pedalling boats. The first boat  was brought to the lake from Tuticorin.  There is also a Kodaikanal Boat Club. The lake is rich in a variety of flora and fauna with different species of fish and aquatic plants. Kurinji or Strobilanthes cynthiana, which blooms once in 12 years, is found in the catchment area of Kodai Lake. Flower shows in summer are yet another attraction of the place. People cycle or go on horse rides around the lake. Tourists also have the option of taking bicycles on rent. There is ample space for parking near the lake. There are also recreational sports activities for children near the lake.
