Mudumalai Wildlife Sanctuary

In the luxuriantly forested foothills of the Nilgiri, this 321 sq. km sanctuary is part of a much larger reserve (3000 sq km ) which includes Bandipur and Wynad in neighbouring Karnataka and Kerala. The larger reserve ranges in vegetarian from semi-evergreen forests to swamps and grasslands. In Mudumalai, the mostly dense forest is home to chital, gaur, tiger, panther, wild boar and sloth bear. The park's wild elephant population, one of the largest in the country, supposedly numbers about 600, however you're more likely to see their domesticated brethren carrying out logging duties. The best time to visit Mudumalai is between February and June. Heavy rain is common in October and November and the park may be closed during the dry season.
