Sultanpur National Park
Sultanpur National Park, located in the Gurgaon district of Haryana about 46 km from Delhi, is witnessing a major increase in migratory birds as winter temperatures drop. The Sultanpur Jheel is a seasonal freshwater wetland whose water levels rise and fall depending on rainfall and seasonal inflows. This shallow lake is mainly replenished by water from the Yamuna River’s Gurgaon canal and by overflow from surrounding agricultural fields. It was designated a Ramsar Site in 2021, recognising its global ecological importance.
