Dudhwa is a relatively uncommercialised park compared to India's more well known reserves such as Bandhavgarh and Kaziranga. Consequently, it is possibly a more natural experience to find animals living in this untouched environment. It is also one of the finest few remaining examples of the exceedingly diverse and productive Tarai eco-system. Dudhwa Tiger Reserve is actually comprised of three sanctuaries; Dudhwa National Park, Kishanpur and Katerniaghat Wildlife Sanctuaries. The northern edge of the reserve lies along the Indo-Nepal border and the southern boundary is marked by the river Suheli. It is a well known sanctuary of the swamp deer (also know as Barasinga) and is also home to tigers, leopards, varieties of deer, antelopes, elephants, rhinos, jackal, hyena etc, amid thick green forest and grassland. It is also excellent for bird watchers' - especially around the large lake.
Safaris are undertaken either by jeep or by elephant - this is one of the few parks in India where elephant safaris are possible.
The best time to visit Dudhwa National Park is between November and May. The park remains open to public from 15th November to 15th June, though the months of May and June are a little too hot for comfort. While visiting the Park during winter you must remember to take woolen clothes as it can get pretty chilly, particularly between December to February.
