The Itanagar Wildlife Sanctuary is very rich in Wildlife both in variety and number. Animals like Elephants, Tigers, Panthers, Sambar, Barking Deer and Bears are quite common. The State bird of Arunachal Pradesh, the magnificent Hornbill used to be found in the Sanctuary, but their population came down drastically due to loss of habitat. However, the Wildlife is still available in a fair number especially in the northern and eastern side of the Itanagar Sanctuary. The INWS is open throughout the year. But the best time to visit the zoo is during October to April. Visitors can have spectacular view of different species of endangered wild animals and birds in the sanctuary.
