This trek combines the green of the Kinnaur region with the stark desolateness of the Spiti valley. The trek begins at Kafnoo in Kinnaur and crosses over the Pin Bhaba pass at 4865 meters, the most frequently used crossing by the locals.
The trail ascends along the left bank of the Wangar River after crossing a footbridge. The path climbs through single crop fields of Mastrang and passes through a mixed forest of conifers and temperate broad-leafed species. The trail climbs through little clearings of potato and buckwheat till it reaches the meadows of Mulling (3350 meters), fringed by birch and birdcherry, leaving the Wangarriver far below. The trail continues to the alpine meadows of Kara, along the banks of the Wangar (Bhaba) gad where one can find numerous “gaddis” (shepherds). This is an ideal camping site. From here the trail continues to Phustirang, a sheltered glade with a spring at one end, which forms the base for the ascent over Bhaba Pass. It is a steep ascent to the pass, over shale and snow, which is marked by typical prayer flags. The descent to the Pin valley, initially over snow, is more gradual over boulder-strewn glaciers.The barren terrain is a sharp contrast to lush green Kinnaur.
The boulder strewn trail continues along the banks of “TariyaKhad”, which eventually feeds into the Pin River. The barrenness is broken by the lush green pastures called Paldar, along the banks of the Pin River. As one walks along the trail, high above the Pin river one catches sight of the Mud Village, an awesome sight with the mountain vistas forming its backdrop. The multi-hued mountain vistas enroute to Mud will leave an indelible imprint in your memories.
