The Kerala Backwaters are a network of interconnected canals, rivers, lakes and inlets, a labyrinthine system formed by more than 900 km of waterways. 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. This backwater waterways lying parallel to the Arabian Sea coast (Malabar Coast) of Kerala state in Southern India.The backwaters have a unique ecosystem: freshwater from the rivers meets the seawater from the Arabian Sea. A barrage has been built near Neendakara Kollam, so salt water from the sea is prevented from entering the deep inside, keeping the fresh water intact. Such fresh water is extensively used for irrigation purposes.
Many unique species of aquatic life including crabs, frogs and mudskippers, water birds such as terns, kingfishers, darters and cormorants, and animals such as otters and turtles live in and alongside the backwaters. Palm trees, pandanus shrubs, various leafy plants and bushes grow alongside the backwaters, providing a green hue to the surrounding landscape.We travelled from Alleppy to Kottayam town which about 30 Km on waterways.
