With its breathtaking landscapes and rich biodiversity, Rajaji Tiger Reserve is a paradise for nature lovers and wildlife enthusiasts. Nestled along the hills and foothills of the Shiwalik ranges, the reserve represents the unique Shiwalik ecosystem. Its terrain hosts a variety of forest types – from semi-evergreen to deciduous, and from mixed broad-leaved forests to Terai grasslands – and is classified under the Indus-Ganges Monsoon Forest type. Towering strands of Sal trees (Shorea robusta) dominate much of the landscape, creating a majestic canopy. Located in a transition zone between the temperate Western Himalaya and the Central Himalaya, the reserve enjoys exceptional species diversity, offering remarkable wildlife viewing opportunities.

Rajaji Tiger Reserve is home to a healthy population of tigers and Asian elephants, along with a diverse range of wildlife such as leopards, jungle cats, Himalayan black bears, sloth bears, striped hyenas, gorals, sambars, wild pigs, spotted deer, barking deer, and many more. It is also a sanctuary for an impressive variety of birdlife, including vultures, woodpeckers, hornbills, and migratory species like the ruddy shelduck, great cormorant, red-crested pochard, and mallard duck. The rivers and streams that traverse the reserve provide aquatic habitats where around 42 species of fish breed. In addition, the reserve shelters notable reptile species such as the king cobra, Burmese python, and common krait.
