The backwaters of Kerala are a network of man made and natural canals that were historically built to provide the only transport available to the local population to bring produce to and from the ports. Although still playing a major part in the everyday lives of the locals, the canals are now also extensively used for tourism, with the rice boats that were once used for transport now reproduced to provide relaxing cruises, with overnight stays if desired, for tourists from across the world.

The locals call Kerala "God's Own Country". It is certainly a "Heaven on Earth", with varied attractions for the tourist from mountainous tea plantations to "paradise" beaches.
