Chitkul (or Chittkul) is a village in Kinnaur district of Himachal Pradesh. During winters, the place mostly remains covered with the snow and the inhabitants move to lower regions of Himachal.Chitkul, on the banks of Baspa River, is the first village of the Baspa Valley and the last village on the old Hindustan-Tibet trade route. It is also the last point in India one can travel to without a permit.
According to a recent study by Centre of Atmospheric Sciences at IIT Delhi, Chitkul has the cleanest air in India.
After one crosses over the 5,242 m high Charang Pass, it is a long and steep run down through slithery scree slopes to Chitkul(3,450m). The powerful goddess of Chitkul is the only non-Buddhist deity to which respect must be paid by the Parikrama pilgrims. It is believed that the local Deity is related to the Deity of Gangotri and till recently the locals would carry the Deity to Gangotri on foot over high mountain passes. Chitkul is situated around 40 km from Karcham, the place where road bifurcates from Hindustan-Tibet Road (NH 22). The Sangla Valley is a delight for nature lovers; especially the stretch after Raksham and right up to Chitkul. The valley is extremely beautiful, on the left bank of the Baspa River are snow-clad mountains and on the right bank the whole terrain is full of apple orchards and wooden houses.
Chitkul is start point for Lamkhaga pass trek and Borasu pass trek. Nagasthi ITBP post is 4km and Ranikanda meadows is 10km trek from Chitkul.
