Sanjay Gandhi National Park
The Sanjay Gandhi National Park area has a long written history dating back to the 4th century BCE. In ancient India, Sopara and Kalyan were two ports in the vicinity that traded with ancient civilisations such as Greece and Mesopotamia. The land route between these two ports was partially through this forest.
