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. This park, ideal for bird watchers, is best visited in winters when a large number of migratory birds come here. In old maps this area is shown as marshy land where water accumulates during rains and dries out in summer. A number of organisms like crustaceans, fish and insects thrive during floods which attract birds to this area. 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 it's potential, the area covering 359 acres was declared a Bird Sanctuary in 1971 and was upgraded to the status of National Park in 1991.

Efforts are being made to improve vegetation in area by planting more trees like Acacia Nilotica, Acacia Tortilis, Beris and Neem have been planted. 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. To facilitate bird watching, there are four watch towers (machans) located at different points. In addition there is parking and facilities for toilets and drinking water.
