Borasu Pass Trek

Trek to the Valley of Gods through the magical villages lost in time

Borasu Pass Trek

Borasu Pass or Bara-su is a high mountain pass that is located on the border of Uttaranchal and Himachal Pradesh along the border with Tibet. It was an ancient trade route between Har ki Dun valley and Kinnaur valley. It is no longer used by the locals and is an escapade for trekkers and mountaineers.

The trek starts from Taluka and passes through the lush green Har ki Dun valley. Har ki Dun is a hanging valley in the Garhwal Himalayas, surrounded by magnificent Himalayan peaks and dense forests flocked with colourful birds and wild life. The trek starts by following the boisterous Har ki Dun Ganga and ends with the colossal Baspa River. One can stay in the Forest Rest House in leisure or camp near Har ki Dun Ganga. Also, one can camp near the beautiful glacial lake at Maninda Tal a few km from Har ki Dun.
