I always loved the Sigur Region in the middle of the Nilgiris Biosphere Reserve. People are nice and nature magnificent. You will find here a diversity of traditional cultures, beautiful jungles with tigers and elephants. Still, if you are interested in culture or nature and you envisage to visit this region, think twice.
The jungle is littered with plastics and replete with cattle. Loudspeakers are in all villages (a blatant ignorance Supreme Court orders) blasting their awful popular music up to three kilometers in the jungle, days and nights for weeks. Roads are loaded with speeding, honking or picnicking cars. For a few hundred Rupees (more), your driver can annoy a herd of elephants to make a female charge. You can flash a tiger at night, with the satisfaction that you have endangered this species more, a princely pleasure. Chance is that bonfires will be with forest wood or the “food” (it’s for tourists) you eat in the village has also been cooked with forest wood. If there is left over, you can throw it to an elephant.
If you like responsible ecotourism (I may be tired with continuous “music” for the last few days), wait and see if it improves.
