During the months of August ? September, Kerala comes alive with festivity at the boat races, the biggest and most spectacular events of Kerala.

There is great excitement as teams of rowers row in unison to the animated rhythm of drums, cymbals, singing of the vanchipattu (song of the boatman) and the cheering of the onlookers. Watching the 100 ft long chundan vallams (snake boats) slice through the water at a frenetic pace is indeed an enthralling spectacle. It is estimated that these boat races draw more than 3 lakh visitors from all over the world.
