Borasu Pass

Borasu pass trek itinerary covers the breathtakingly beautiful Har-ki-Dun valley, and we witness the beautiful glacial lakes of Morinda Taal and Zhukia (also spelled as Zhupkia) Glacier. The route for this trek passes through:

  • A long glacier.
  • Glacial moraine stretch.
  • Narrow ridges.
  • Mountain meadows.
  • and numerous boulders.

Overall a very adventurous experience not to mention the unforgettable views of the Kinnaur-Garhwal mountains.

The views from the Borasu pass, looking back into the Har Ki Dun valley along the way we came, were spectacular to say the least. So, were the views of the glacier on the other side of the valley.
