Sasthamkotta Lake – Kerala’s Tranquil Freshwater Wonderland
Tucked amidst rolling green hills and lush coconut groves in Kollam district, Sasthamkotta Lake — often called the “Queen of Lakes” — is Kerala’s largest freshwater lake and a natural paradise of peace and purity. Spanning over 375 hectares, this pristine lake is not only the lifeline of Kollam city’s drinking water supply, but also a serene escape for nature lovers, photographers, and peace seekers.
If you’re looking for an offbeat Kerala experience, far from the crowds, Sasthamkotta Lake welcomes you with mirror-like waters, soothing silence, and the gentle rhythm of rural life.
A Natural Wonder Born of Serenity
Sasthamkotta Lake derives its name from the ancient Sastha Temple situated on its banks, dedicated to Lord Ayyappa, the presiding deity of Sabarimala. The temple’s surroundings are home to playful monkeys, considered sacred, making the visit even more memorable!
The lake’s water is incredibly pure — naturally filtered by larvae that remove bacteria — giving it crystal clarity. The scenic beauty of this freshwater expanse, framed by hills and tropical greenery, makes it a paradise for photography and relaxation.
