The park is part of a larger, interconnected green belt that includes the Rose Garden and the District Park, spanning over 500 acres total.
The water body, known as Hauz Khas, was originally an artificial lake created by Alauddin Khilji to provide water to the residents of Siri.
The deer population in the enclosure is actively monitored by the local forest department to maintain health and population density.
The park's ruins are protected under the Archaeological Survey of India (ASI) mandate, distinct from the surrounding DDA-maintained landscape.
The lake receives treated water from local sewage treatment plants to maintain its levels during the hot summer months.
Despite the name, the park hosts a wide variety of wildlife beyond deer, including mongooses, rabbits, and dozens of avian species.
Deer Park Lake is an urban green space integrated into the larger Hauz Khas District Park complex in South Delhi. The area features a central reservoir surrounded by walking trails, wooded tracts, and historic 14th-century architectural ruins from the Delhi Sultanate period. The park is home to a protected enclosure housing spotted deer, which are visible from designated viewing areas. Its terrain is undulating and incorporates mature canopy trees providing significant urban shade. The site serves as a vital ecological corridor for local bird species, including peacocks and migratory waterbirds during winter. The ruins include tomb structures and remnants of mosques that overlook the water body. The park is managed by the Delhi Development Authority and is interconnected with the Hauz Khas Village urban center. It functions as a recreational space for walkers, joggers, and photography enthusiasts.

Bring a pair of binoculars if you are interested in bird watching, as the lake attracts diverse species.
Stick to the marked paved paths to avoid uneven terrain and potential thorny vegetation.
Carry your own drinking water as facilities within the park grounds are sparse.
Do not wander into the unlit, forested sections after sunset due to poor visibility and limited security patrols.
Maintain a respectful distance from the deer enclosure fence; feeding the animals is strictly prohibited.
