Houseboat on the backwaters in Kerala, India.

The Kerala backwaters are a network of brackish lagoons and lakes lying parallel to the Arabian Sea coast (known as the Malabar Coast) of Kerala state in southern India, as well as interconnected canals, rivers, and inlets, a labyrinthine system formed by more than 900 kilometres (560 mi) of waterways, and sometimes compared to American bayous.[3] The network includes five large lakes linked by canals, both man made and natural, fed by 38 rivers, and extending virtually half the length of Kerala state. The backwaters were formed by the action of waves and shore currents creating low barrier islands across the mouths of the many rivers flowing down from the Western Ghats range. In the midst of this landscape there are a number of towns and cities, which serve as the starting and end points of backwater cruises The kettuvallams (Kerala houseboats) in the backwaters are one of the prominent tourist attractions in Kerala. More than 2000 kettuvallams ply the backwaters. The Kerala backwaters is the rather unappealing name given to the peaceful and picturesque palm-lined network of lagoons, lakes, rivers, and canals that run inland from the coast of Kerala, from Kochi (Cochin) to Kollam (Quilon) in India. The main entry point, situated between Kochi and Kollam, is Alleppey (Alappuzha). At the heart of the backwaters is vast Vembanad Lake.

Traditionally, the backwaters are used by locals for transport, fishing, and agriculture. Annual snake boat races, held along the backwaters, also provide a great source of entertainment for the locals and tourists alike.

The lush green landscape, diverse wildlife, and houses and villages that line the backwaters make a journey along these waterways seem like a journey through another world.
