The famous regatta or snake boat race known as Aranmula Vallamkali is an extension of the popular Onam festival of Kerala in South India, taking place on the 4th day after Onam festivities end, during August/September.

More than 30 snake boats, called chunadan vallams participate in the race. The race takes place in the holy river of Pamba and is connected with the famous Sree Parthasarathy Temple of Aranmula.

This boat race is historic in origin and is still imbued with rituals. One thing special about this boat race is that the racing speed is not of much importance and is more a ritual.
