Deer Park, Public park in Hauz Khas, India

It is divided into four wings: Rose Garden, Deer Park, Fountain & District Park, and Old Monuments with the Hauz Khas Art Market. A large enclosure holds the deer, and the park also has a Duck Park, picnic spots and rabbit enclosures. A wide pale paved path slopes gently between low concrete walls, flanked by trees.
