Kathakakli is the classical dance drama of Kerala based on the guidelines laid in the Natya Sastra. This elaborate art form is usually begins in the evenings and continues till dawn. It is an inherent part of all temple and cultural festivals in Kerala. The costumes and makeup are ornamental, colorful and elaborate so that the gestures and expressions of the performer are easily seen and understood. The performers do not speak or sing but enact the story through hand gestures, graceful body movements and facial expressions especially of the eyes. The themes of this dance form are from rich and vibrant mythology of Indian culture. Music is an essential feature of Kathakakli and two vocalists are there who sing to the beats of a chengila (gong), elathalam (small cymbals), chenda and maddalam.
The state's tourism agenda promotes ecologically sustained tourism, which focuses on the local culture, wilderness adventures, volunteering and personal growth of the local population. Efforts are taken to minimize the adverse effects of traditional tourism on the natural environment, and enhance the cultural integrity of local people. The backwaters in Kerala are a chain of brackish lagoons and lakes lying parallel to the Arabian Sea coast (known as the Malabar Coast).
Houseboat in Kerala commonly known as Kettuvallam in the backwaters is one of the prominent tourist attractions in Kerala. Alleppey known as the "Venice of the East" has a large network of canals that meander through the town. The Vallam Kali (the Snake Boat Race) held every year in August is a major sporting attraction. The backwater network includes five large lakes (including Ashtamudi Kayal and Vembanad Kayal) linked by 1500 km of canals, both manmade and natural, fed by 38 rivers, and extending virtually the entire 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.
