Nag Tibba is a hill station in Dehradun, located in the Mussoorie-Nag Tibba range, at a height of 9,732 feet (2,966 m) above sea level. The hill is a popular tourist destination and is also a trekking point. The nearest town is Pantwari, located at a distance of 10 kilometres. The hill is said to be the home of the serpent king Nag and is thus named after him. The hill is also associated with the Hindu god Shiva, who is said to have performed penance on the hill, which is also believed to be the birthplace of the sage Vyasa.
Apart from its mythological significance, the history of Nag Tibba begins with the Mahabharata. It is said that the Pandavas, after their exile and before their final battle with the Kauravas, spent some time in the Himalayas. During their sojourn there, they visited Nag Tibba and were awestruck by the sight of the snakes coiled around the peak. The earliest recorded mention of Nag Tibba is from the 7th century, when it was mentioned by the Chinese traveller Huen Tsang. In his travelogue, he writes that the peak was a place of worship for the Nagas (snakes). Besides, the first European to visit Nag Tibba was Captain William Moorcroft, who climbed the peak in 1824, followed by other explorers, including Alexander Cunningham, who surveyed the area in the 1860s.
Nag Tibba was declared a protected area in 1992 and is now a part of the Rajaji National Park. Today, the hill is a popular tourist destination and is also a trekking point.
