In the foothills of the Nilgiris, this newly enlarged 765-sq-km wildlife reserve is like a classical Indian landscape painting given life, with chital deer, wild boar, gaur (Indian bison), peacocks, langurs, jackals, Malabar giant squirrels and wild elephants concealed between thin, spindly trees and light-slotted leaves. Also here are over 60 tigers – though you'd be incredibly lucky to see one. Overall, Mudumalai is Tamil Nadu's top wildlife-spotting place.
