Borasu pass crosses into Himachal from Uttarakhand and connects the Tons river valley with Baspa river valley. It takes 3 to 4 days from Har Ki Dun forest to Chitkul in the Baspa Valley. From Har ki Dun the trail goes North with the Marinda Gad (river). After that the ascent becomes easy and the path winds up for about 5 km through a valley of flowers. This trek gives you a sneak peek into the Himalayan cultures of Garhwal and Kinnaur.
Day 1: Drive from Dehradun to Sankri
We will start our drive early in the morning from Dehradun and reach Sankri by evening. The final stretch is through the Govind Pashu National Park after crossing a check post at Netwar. Our stay at night will be in a guest house or in camps.
Day 2: Sankri to Seema via Taluka
After breakfast, we will travel from Sankri to Taluka. The trek will begin from Taluka on a stony path. The path crosses over streams which merge with Supin. After walking around an hour, the picturesque village of Osla unfolds itself. Seema is a small settlement opposite to the river from Osla and we will set our camp there or stay in a hut with a local family in the village.
Day 3: Seema/Osla to Har Ki Dun
From Osla the trail rises higher and passes through bushes of flowers and climbs above the confluence of Supin River and the river from Ruinsara valley. We will camp at a beautiful spot in Har ki Dun, located at the junction of two valleys - one that originates from Jaundhar glacier and the other from beyond Hata glacier.
Day 4: Har Ki Dun to Ratha Tho
This day we will trek at moderate pace to reach Ratha Tho. We will pass by Morinda Tal, a small lake. The views of snow-clad mountains and wide valleys make it a beautiful walk.
Day 5: Ratha Tho to Borasu Pass Base Camp
On this day, we will walk higher up. The path is over boulders and often covered with snow. From here you will get a beautiful view of the valley behind.
Day 6: Borasu Pass Base Camp to Bonga via Borasu Pass
This day we will start our trek before sunrise. The views will unfold as we keep moving higher up. We will have to cross two glaciers and a final ascent over boulders, after which the Borasu pass will lie before us. We will descend towards the Himachal side of the pass into a large glacier usually glissading over the slope.
Day 7: Bonga to Chitkul
The last day’s trek will take around 8 hours which will be an easy walk through fields of flowers and forests. We will spend the night in Chitkul Village. The trek ends here. The trekkers can get public or private transport from Chitkul or Sangla to Shimla.
