Religious aspect: The area is well recognized by its religious and cultural value. Renuka is an abode of temples of the mother-and-son duo of Renukaji and Lord Parshuram. Mythologically Renukaji is an incarnation of Goddess Durga. She was the wife of Rishi Yamdagini. Parshuram believed to be the sixth incarnation of Lord Vishnu. He was the yongest of the five sons of the couple. It is believed that in order to obey the command of his father, Parshuram had to serve the head of his mother. After killing his mother, he begged his father to prejure life in his mother, for which the Rishi agreed. Renukaji was considered extremely beautiful. Sahastarvahu, the emperor, wanted to marry her and once when Parshuram was away, he killed Rishi Yamdagini and his four sons to marry Renukaji.

To escape the clutches of the emperor Renukaji jumped into small pond, known by the name of the Ramsarover at that time, and vanished into it. Ever since the lake is worshiped as Renuka lake.

The first animal brought here was a male spotted deer named Moti. To accommodate the increasing number of animals, an open park was conceived and the park was established in 1983. Black Buck and Nilgai were brought from Pipli Zoo. A pair of Mithun, gifted by Rajiv Gandhi, the Prime Minister of India in 1985, was brought from Arunachal Pradesh and another was brought from Nagaland in 1986. A pair of lions was brought to the zoo from Zunagarh in 1975.
