Kunnathur Taluk headquarters is at Sasthamcotta which is an attractive village situated about 19 Km from Kollam Town. It is a beauty spot, a health resort and a centre of pilgrimage.

The extensive fresh water lake here is said to be the biggest of its kind in Kerala. Water supply to Kollam Town is met by purifying the water from this lake.
