The wildlife sanctuary covers an area of about 550sq.km. and is inhabited by a number of animals including elephants, sloth bears, bison, deer, porcupines and a number of other wild animals. It is said that the sanctuary has more than 250 species of birds like the Paradise Flycatcher, Racquet Trailed Drongo and the Crested Hawk Eagle, to name a few. The sanctuary is inhabited with such a large population of wildlife that one does not have to go looking for them. There is accommodation in the sanctuary in the form of Jungle lodges and resorts. The best time to get a good look at the wildlife is at dawn.
To visit the temple on top of the hill you can either climb the 150 steps leading to the temple or drive through the lush green forests. The temple is dedicated to Biligiri Rangaswamy and the temple is built in the Dravidian style. There is a guesthouse maintained by the temple authorities that provides accommodation as well. These hills are a wonderful combination of a hill resort and a wildlife sanctuary. There are buses that ply from Mysore at regular intervals to B.R.Hills.
