Detailed Overview

Borasu pass is one of the many passes that cross into Himachal from Uttarakhand. It connects the Tons river valley with Baspa river valley. The pass is open only for a few months before monsoons and then for a month or two before the winter sets in. This itself explains the uniqueness of this trek. The trek to Borasu is high but doable. We trek into the great Kinnaur Valley and takes 3 to 4 days from Har Ki Dun forest rest house to Chitkul road head in the Baspa Valley. From Har ki Dun the trail heads north along the Marinda Gad. Beyond that, the ascent eases and the path winds up for 5km through a flower-strewn narrow valley. With a glacier on the further right and a strenuous climb for about 4 km, the pass unwinds itself. Descend the rocky slopes and down to the Baspa bed. Cross the river by a bridge and reach the Doaria campgrounds. From Doaria the trek to Chitkul is very easy. This trek is one of the best ways to experience the Himalayan culture of Garhwal and Kinnaur.
