Sita Gupha is situated in Panchawati area about 3 km away from the Nashik Central bus stand.
It is said that Seeta stayed in this caves for some days during exile(Vanvas). The deities of Ram, Seeta and Laxman are placed inside the first main gummpha. In the second small gupha there is a Shivling . The main reason attributed for the Shivling is that Seeta used to worship God Shiva and she never took her meals before worshiping him.
So for her convenience Shivling was placed in that gupha. It was in this cave that Lord Rama used to hide Sita when he had to leave her, and it was from here that Sita was carried by Ravana disguised as a bagger.
