The major annual festivals are "Oachira Kali" or "Oachirakali" and the twelve-day Panthrandu Vilakku , which is held in November/December. Oachira Kali is celebrated in commemoration of the battle of Kayamkulam, fought between Marthanda Varma, the Maharaja of Travancore and the Raja of Kayamkulam. It is a mock fight enacted between groups of men dressed as warriors on the "padanilam" (battlefield).
