Kerala Backwaters 

Backwaters are a chain of brackish lagoons and lakes lying parallel to the Arabian Sea coast. The network includes five large lakes (including Ashtamudi lake and Vembanad lake) linked by 1500 km of canals, both manmade 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. Kumarakom and Alleppey are the prominent backwater destinations of kerala.
