In a mythological account, this picturesque lake is said to be one of the emerald green eyes of Shiva's beloved consort, Sati (nain is a Sanskrit word for eye). When Sati's father failed to invite Shiva to a family sacrifice, she burnt herself to death in protest. Shiva gathered the charred remains in his arms and proceeded to engage in a cosmic dance tandav, which threatened to destroy the creation. To bring the dance to an end, Vishnu chopped up the body into pieces, and the remains were scattered. The Naina Devi Temple at the northern end of the lake is built over the precise spot where the eye is believed to have fallen.

From the Nainital town the Snow View top is a 3 kilometer trek. Part of it can also be covered comfortably by cars and small vehicles. At the top, one can have a close up view of Nanda Devi (7816m), the second highest Himalayan peak of the country.

There's a small temple dedicated to Dev Mundi, housing images of Goddess Durga, Lord Shiva, Goddess Sita, Lord Rama, Sri Lakshmana and Sri Hanuman. From Snow View one can walk west to another point and then continue on to the main road to Kilbury. One can also continue up to Cheena Peak or head down the road to Sukhatal, passing great views of the lake en route. On the walk up to Snow View one can take a peek in the tiny Gadhan Kunkyop Ling Gompa of the Gelukpa order (of which the Dalai Lama is the spiritual head).

Naina Peak is locally known as the Cheena peak. This is the highest point in Nainital. From here Nainital appears like a majestic shining bowl. You can walk or take ponies to reach the peak. Naina peak also gives a good view of the Camel's Back, another interesting peak. There are no hotels or restaurants on the top so it is advisable to carry food and water along.

The place is of great religious importance. Situated at a height of 1951 meters, this place was established by Baba Neem Karauli. A very beautiful Hanuman temple is at the top. Watching the Sunset from Hanuman Garhi, is an out-of-the-world experience. You can leisurely walk down to Hanuman Garhi from Nainital town.

Nainital has a small but a very beautiful Zoological garden. There are several animals including Deer, Bears, Tigers and many more. Special efforts have been put in to make the environment of the zoo hygienic and clean. Not surprisingly this zoo is one of the cleanest zoos in the country. The zoo can be reached on foot or by small vehicles.
