About Borasu Pass Expedition

8 Days
17,881 FT
Moderate

Borasu Pass at 17,880 ft is one of the highest trekking passes in Uttarakhand, connecting the Har Ki Dun valley to Kinnaur in Himachal Pradesh. This 8-day expert-level trek crosses glacial moraines, crevassed snowfields, and a dramatic pass that straddles two states. Borasu is the ultimate trans-Himalayan crossing for experienced high-altitude trekkers seeking a genuine expedition-grade challenge with virtually zero commercial traffic.

Common Questions

How difficult is the Borasu Pass trekking crossover?
It is a difficult trek (Altitude 17,200 ft). It involves walking on steep snowfields, potentially navigating glacier surfaces, and a very long descent on the Sangla side.
Where does the trek start and end?
The trek starts from Sankri in the Tons Valley of Uttarakhand and ends at Chitkul in the Sangla Valley of Himachal Pradesh.
Do I need a Border Permit?
Yes, since it crosses the state border and is near the sensitive Indo-Tibet frontier, Inner Line Permits are checked at the Dunwari and Chitkul ITBP posts.
What is the best month for snow in Borasu?
June and early July offer the most snow on the pass. For a relatively dryer (but colder) crossing, September is preferred.
What peaks can we see from Borasu?
You get incredible views of Black Peak (Kalanag), Swargarohini, and the Kinnaur Kailash range on the Himachal side.
Is it suitable for solo trekkers?
No. The route is remote and pass navigation requires a professional guide and a reliable logistics team.
How cold it gets at the base camp?
Nights at the higher camps (above 14,000 ft) often drop to -10°C even in peak summer months.
