Traditionally, the houseboats were called Kettuvallams, which means a boat made by trying together pieces of wood. Unbelievable as it may sound, not a single nail is used in the making of a Kettuvallam. Jack wood planks are joined together with coir rope and then coated with black resin made from boiled cashew nuts shells.
The Backwaters of Kerala is unique and is found nowhere else in the world. Backwaters are a network of lakes, canals and estuaries and deltas of forty-four rivers that drain into the Arabian Sea. The backwaters of Kerala are a self supporting eco-system teeming with life. The canals connect the villages together and are still used for local transport. Over 900 km of this labyrinthine water world is navigable
The most exciting aspect of Kuttanadu is the Kettuvallam (traditional Houseboat) which has become the most popular tourism product in India today. In a land as water bound as Kerala it wouldn't be an unusual sight, but for a visitor to God's Own Country a houseboat gliding along the vast green expanse of the backwaters is the most amazing spectacle in the world. Even more enchanting is a holiday in the houseboats of Kerala.
