Debsa Pass

Debsa Pass is a 5,360-metre crossing in the Himalaya on the watershed between Kullu and Spiti in Himachal Pradesh. It was found by teams led by Joydeep Sircar, who came up the Parbati River valley from the Kullu side. After a failed try at an impassable col further north in 1992, they reached the pass in 1993 but turned back, wrongly believing they could be arrested in Spiti without Inner Line Permits.

A 1995 team meant to come from Spiti, the side with far less climbing, but severe autumn floods in the upper Beas valley wrecked the roads and sent them up the Parbati again. On 21 September they crossed and completed the route from Manikaran to Kaza. The line leaves the valley between the Kachh and Bara Dwari Thach campsites, crosses the divide onto the West Debsa Glacier, then follows the West Debsa and Debsa streams down to Thango in the Parahio Valley.
