Situated on a forest range on the Thiruvananthapuram – Shenkottai road, Kulathupuzha is known for the Sastha temple. The Vishu Mahotsavam in April/May is the most important festival. There are frequent buses from Kollam to Kulathupuzha. The Thenmala railway station is just 10 km from here.The Sastha Temple at Kulathupuzha is very ancient. The idol at Kulathupuzha is called ‘Manikandan’. It is believed that the Temple was constructed by the Raja of Pandalam. But the idol was discovered by a Brahmin from Kottarakkara after several years and he started pooja there. The King of Kottarakkara heard about this and constructed the present temple. Feeding to the fishes in the nearby river is an important ‘vazhipadu’ in the Temple.
