The Aranmula vallomkali in the Aranmula River in Pathanamthitta district, is one of Kerala's most popular water fiestas. Conducted annually, the Aranmula Vallomkali is part of the Onam celebrations. This water regatta, unlike the other boat races of Kerala, is not a contest but a retracing of a ritualistic journey undertaken to the Aranmula temple in days gone by.

Thousands of excited people throng the waterside to cheer the majestic crafts that slice through the waters with hundreds of oarsmen roaring in rhythm to the boatman's songs.</br/></br/>
