Nag Tibba is one of the most unique and historical treks. The base for this trek is a place called Panthwari which is a 70 km drive from Dehradun via Mussourie. You will go through dense deodar forests to reach the base of Nag Tibba at Nag taal where you camp for the night. In the morning you will go to the summit of Nag Tibba and return to the base same day and on the third day return from the other side of the ridge via Pantwari.
During the trek you will find yourself at almost 10,000 ft which is the highest point in the lower Himalayas. You will be enchanted by a panoramic view of the snow covered Himalayas, including the Bandarpunch and Swargarohini range and even the Nanda Devi in the distance. Overnight stay with camping gear is recommended for trekkers because there is no accommodation at the place. The nearest accommodation is Devalsari guest house. A day trek is the other option, but is very arduous. An important thing to note is that water is scarce along the route and is usually carried by the trekkers.
The trek through Nag Tibba Range, finds mention in the book Seven Years in Tibet, which chronicles the journey of mountaineers, Heinrich Harrer, Peter Aufschnaiter in May 1944, towards Tibet.
In total, the trek lasts 4 days from Dehradun to Dehradun or from Rishikesh to Rishikesh.
