The temple is located about 1.5 km southeast of the bus stand. It is assumed that an idol of ‘Kannaki’, a deity of the temple was installed about 1800 years ago by Cheran Chenkuttuvan of the Chera dynasty. The presiding deity of the temple is ‘Bhadrakali’ (Goddess Kali). On the eastern side of the main shrine there is a secret chamber from which a door opens to the shrine. The most famous festival of the Kurumbakavu temple is the Bharani festival which starts on the Bharani asterism, as per the month of Meenam (March-April) of the Malayalam calendar. The animal sacrifices that once were part of the festival in this temple are now banned, but the pilgrims still drink liquor and sing lewd songs, all the way on the pilgrimage from their villages to the shrine, as part of the rituals.
