As a penultimate day before the Pass Crossing day, this day serves as the last chocolate bar before hitting the trail leading to the summit of the pass. A short day at an altitude above 4500 meters. It makes sense to make it shorter. The terrain gives no relief though.

The toughest day of the trek. An effort of some 3 hours over steep terrain of snow over scree zone takes us to the summit of the pass. From here, you can see back your trail and start imagining your past days and the effort you put to reach till here. However, things are not complete yet. There is a tactful descend to negotiate which still maintains the difficulty of the trek. A campsite exists just after descending down the pass, but it is advisable to reach the welcoming meadows of Bonga and rest out the night.

Top Reasons to Choose the Borasu Pass Trek
- The Borasu Pass lies on the border of Himachal Pradesh and Uttrakhand and it served as the ancient trade route and Gateway Of Cultural Exchanges between Kinnaur, Tibet and Jaunsar.
- The altitude of Borasu Pass, also known as Barasu Pass, is above 5400 meters and is a very high altitude pass crossing trek in the Himalayas.
- The terrain of this trek goes through a dense forest of tall coniferous trees, which transforms into alpine grasslands, scree zones, glacial moraines and then the crevassed glaciers on both sides. It definitely makes an engaging and strenuous trek all the way to Chitkul starting from the beautiful hamlet of Sankri.
- Zupica glaciers is a contributary water source of the Baspa river, which originates from the Baspa Bamak higher up on the same valley.
- The hospitality of both the valleys that the Borasu Pass connects is awesome and most welcoming for a traveller. The people here are strong, hardy but always with a smile on their face.
- Both of the valleys of Sankri and Kinnaur have their unique dialect and cuisines. The food they cook is unique, tasty and very organic.
- On this trek, we pass by the campsite of the very popular Har Ki Dun and Kalkati Dhar. Both these campsites are wonderful place to be in and very photogenic.
- The Swargarohini massif looks gigantic from the camp of Har Ki Dun and on the excursion to the Jaundhar Glacier viewpoint. It is a massif of 6 peaks, 4 of which are visible from Sankri.
- From the campsite of Halche, before reaching Kalkati Dhar, we can even see the twin peaks of Bandarpoonch and Kalanag. Both demonstrate epic Himalayan glory.
- Maninda Tal is a small lake formed by the blocked water of the Borasu Gad. It is very serene, but what makes it a highly revered place is the surrounding mountains, meadows and valleys. It is very beautiful and camping here makes it really worth it.
