Sultanpur National Park & Bird Sanctuary is located in Gurgaon district of Haryana, 50 km from Delhi and 15 km from Gurgaon on the Gurgaon-Farukh Nagar road. Winters are the best time to visit this park when a large number of migratory birds make their presence felt.

It's potential as a bird preserve was first identified by an enthusiastic bird watcher, Mr. Peter Jackson. He convinced Mrs. Indira Gandhi, the then Prime Minister, of the need for giving protection to this area. Keeping in view its potential, the area covering 359 acres was declared a Bird Sanctuary in 1971 and was upgraded to the status of National Park in 1991.

To facilitate bird watching, there are four watch towers located at different points inside the park. In addition there is parking and facilities for toilets and drinking water. For birders and tourists, interested in staying for the night, there is a resort just near the entrance providing food and lodging. For the benefit of bird lovers certain facilities have been provided like an education and interpretation center, a library as well as films, slides and binoculars.
