At a distance of 20 kms from Kannyakumari (situated in Nagarcoil town, on Trivandrum - Kanyakumari road), The Nagaraja Temple is a simple thatched shed, with mud walls.
It enshrines the King of Serpents. Tradition states that a King of Kalakkad was cured of leprosy when he performed penance in the temple. He then rebuilt it in the Kerala style. He might have been Bhuthalavira Sri Vira Udaya Marthandavarma, who ruled Venad, with Kalakkad as the capital. It is believed that snakebite is not fatal within a kilometer of the temple.
Temple timings: 5.30 AM - 10 AM & 5 PM - 7 PM
