Rajaji is thickly foliated predominantly by the Sal Forest and a number of other forest types which include the Western Gangetic Moist and Northern dry Deciduous and Khair-Sissoo forests. Low Alluvial Savannah Woodlands cover the drier southern margins of the park, in contrast to the Siwalik Chir-Pine on the high reaches of the hills.

The park is home to the Cheetal, hog deer, barking deer, Sambar deer, wild boar,  antelopes such as the Nilgai, Goral and of course the Asian Elephant.

 The park also protects carnivores such as the Tiger and the Leopard and the lesser carnivores like the Jackal, Hyena, Jungle Cat, Leopard Cat, Civets, Himalayan Yellow-Throated Marten and Sloth Bears.

The park also houses over four hundred bird species. The Great Pied Hornbill, Himalayan Pied Kingfisher and fire tailed sunbird are some of the residents of our retreat.

This area is the first staging ground after the migratory birds cross over the mighty Himalayas into the Indian subcontinent.

Rajaji National Park and the Wild Brook Retreat give you all the excitement and exhilaration of holidaying in the heart of the Indian wildlife. Just where all the action is. In the lap of Nature at its most raw and where the law of the jungle prevails. Predators prowl the wild pathways, the deer call for help, birds shriek in the skies and reptiles slither across the earth.
