Road Distance or driving distance from Rishikesh to Nainital is 240 kms (150.00 miles). 

Nainital is a popular hill station in the Indian state of Uttarakhand. 

Situated at an altitude of 2,084 metres (6,837 ft) above sea level, Nainital is set in a valley containing a pear-shaped lake, approximately two miles in circumference, and surrounded by mountains, of which the highest are Naina (2,615 m (8,579 ft)) on the north, Deopatha (2,438 m (7,999 ft)) on the west, and Ayarpatha (2,278 m (7,474 ft)) on the south. 

It is believed that Nainital figures in some ancient myths of India. In the Manas Khand of the Skand Puranas, Nainital Lake is called Tri-Rishi-Sarovar, hinting at the story of three sages (or rishis), Atri, Pulastya and Pulaha, who, upon finding no water in Nainital, dug a large hole at the location of the present day lake (sarovar = lake) and filled it with water from the holy lake Manasarovar in Tibet. According to lore, a dip in Naini Lake, "the lesser Manasarovar," earns merit equal to a dip in the great lake. 

It is also believed that The Naini Lake is one of the 64 Shakti Peeths, or religious sites where parts of the charred body of Sati (Parvati) fell on earth while being carried by Lord Shiva. The spot where Sati's eyes (or Nain) fell, came to be called Nain-tal or lake of the eye. The goddess Shakti is worshipped at the Naina Devi Temple on the north shore of the present day lake
