Sasthamkotta Lake

Sasthamkotta Lake is the largest freshwater lake in Kerala and one of Kollam district’s most important natural landmarks. Located at Sasthamkotta in Kunnathur taluk, the lake was designated a Ramsar wetland in 2002, recognising its ecological significance. Its broad freshwater expanse supports fish, waterbirds and a distinctive wetland environment, while the surrounding settlement has a strong cultural connection with the historic Sastha temple nearby.

The lake is valued not only as a tourism attraction but also as a vital freshwater resource for the region. Visitors come for quiet views, photography, birdwatching and the contrast between the wooded banks and open water. Where local services operate, simple boating can add another perspective on the landscape.

Sasthamkotta is better suited to slow sightseeing than high-energy recreation, and responsible visitors should avoid disturbing the shoreline or wetland habitats. For travellers exploring Kollam beyond the coast and backwaters, it provides a useful introduction to Kerala’s freshwater ecology and inland cultural landscape.
