A landlocked district, idukki is one of the most nature rich areas of kerala . The high ranges and wooded valleys are girded by three main rivers- periyar, thalayar and thodupuzhayar- and their tributaries. The river pamba also has its origin here. As a tourist destination, idukki offers diverse attractions like wildlife sanctuaries, hill stations, spice plantation tours, mountain treks, elephant rides etc. Idukki has a large population of tribals who have unique customs and beliefs and maintain an ethos which is distinctly different from that of the mainstream culture.
