Rajaji National Park was formed by consolidating three sanctuaries namely Chilla, Motichur and Rajaji and covers an area of 820 sq. km. The area lies towards the east of the Dehradun-Roorkee highway.
More than 500 Elephants, 12 Tigers, 250 Panthers and good prey base including Spotted Deer, Sambhar, Wild Boar, Barking deer, Goral Two kinds of Bears Himalayan Black and Sloth, and over 400 bird species makes Rajaji National Park a perfect wild life and bird watching destination.
Chilla, which is the region open to tourists, is probably the best for viewing wild life. It is also very scenic as it affords views of the mighty Ganga, as well as the Himalayas to the North, together with a large reservoir for water birds. It is located close to the religious center of Haridwar and is just about 20 km away from Rishikesh. There are watchtowers located over water holes and motorable tracks taking one to areas around the park where wildlife can be spotted as one drives along. Herds of Spotted Deer are fairly common to spot. The other animals that can be spotted in the Chilla wildlife sanctuary are the wild boar, Sambhar Deer, the Grey Langur, the Red Rhesus Macaque, the Barking Deer, the Peacock, Quails, Hornbills, Hawks, Falcons, Vultures and many other birds of prey.
