Marinda Tal
Marinda Tal on the way to Ratha Tho - September; PC: Birender Rana

Borasu pass is one of the many passes that cross into Himachal from Uttarakhand. It connects the Tons river valley with Baspa river valley. It is a high but practical traverse 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(river). Beyond that the ascent eases and the path winds up for about 5 km through a flower strewn narrow valley. With a glacier further right, we climb strenuously, for about 4 km to the pass. Then we descend the rocky slopes and down to the Baspa bed. From the camping ground here, the trek to Chitkul is very easy. This trek is one of the best ways to experience the Himalayan cultures of Garhwal and Kinnaur.

Trekkers' safety and comfort are of the utmost priority to us at Himalaya Shelter. This is reflected in conduct of our treks, through our curteous and experienced staff, our equipment standards, hygiene, and respect for the nature and outdoors. We equally value the fragile nature of biodiversity and thus indulge in organizing minimum impact treks, while ensuring an authentic and complete experience for our trekkers.
  • Our Equipment: We use 4 season tents on all our treks to ensure an added layer of safety. We have high quality tents from premier mountaineering equipment companies such as Simond, Vango and Alps Mountaineering.
  • Our Sleepings bags are high altitude ready and ensure comfort during cold weather. We take into account hygiene and thus ensure the cleanliness of our sleeping bags.
  • Our Conduct: Our guides are experienced in the outdoors and always put guest safety first, even if that means making tough decisions.
  • We emphazise on localization as being integral to sustainable growth and thus try to the extent possible to use local food products, which in turn provides trekkers an added experience of getting familiar with local cuisine and culture.
  • At Himalaya Shelter we employ locals while organizing treks, and support their training from institutions such as Nehru Institute of Mountaineering, thus contributing towards rural development through empowering local people.
  • Himalaya Shelter never indulges in setting up of fixed camps which work as achilles heel for the fragile environs of meadows. We urge trekkers to trek responsibly and always raise these concerns with their organizers.

  • Sankri (1,920 m) to Seema (2,560 m) via Taluka (1,800 m)

    Post breakfast we are transported from Sankri to Taluka. The drive is a bit bumpy. The trek commences from Taluka on a stony path. With the river Supin gushing through rapids beside us, under the shade of walnut, pine and other trees, the walk is quite pleasant. Often the passing villagers greet us on the way.

    The path crosses over a few streams which merge with Supin. After a few hours of walk the village of Gangad can be seen towards the left, across the river. We continue our hike and after about an hour's walk, the quaint village of Osla unfolds itself. Seema is a tiny settlement opposite to the river from Osla. We set camp here or stay in a hut with a local family in the village.

    Seema/Osla to Har ki Dun (3,510 m)

    From Osla the trail gradually rises higher and passes through bushes of flowers like orchids, fleece flowers and sunflowers. The ascending path climbs high above the confluence of Supin river and the river from Ruinsara valley.

    After traversing higher up along the left side of the river, we camp at a very panoramic spot in Har ki Dun, located at the junction of two valleys - one originating from Jaundhar glacier and the other from beyond Hata glacier.

After crossing two glaciers and a final ascent over boulders, the cradle shaped Borasu pass lies before us.

We may find shepherds near the campsite.
