The attractive lake of Nainital is said to be the eyes of Sati, wife of Lord Shiva. Sati jumped into the sacrificial bonfire. Lord Shiva to mourn the death of his beloved wife carried the body across the country. The remains of her body fell at various places which today are sacred worship places for the Hindus.
The word Naina is synonymous with Sati's eyes. Since then, devotees started visiting this temple. Once the devotee reaches the hill top, prasad can be bought from any of the various shops or it can also one's own offerings from home. After crossing the main gate, there is a big Peepal tree on the left side. On the right side of the temple there are idols of Lord Hanuman Ji and Ganesh Ji. After reaching the main entrance of the temple, there are two statues of lions.
Inside the temple, devotees have darshan of three deities. On the extreme left is Mata Kali Devi, the centre representing two Netras or eyes is Maa Naina Devi and to right side is idol of Lord Ganesh.
