Day 5: Gangotri BC – Auden’s Col BC (6 km)
This hike is as challenging as previous day’s. but you will probably be accustomed by now. After crossing some moraine path, you will reach your destination for the day – Auden’s Col Base Camp.
Day 6: Auden’s Col BC – Auden’s Col Pass – Khatling Glacier Camp (12 km)
This is the day when you will cross the Auden’s Col Pass. You must start as early as possible. A 5 km uphilltrek for about 4 hours will take you to the Auden’s Col Pass. The trek is quite difficult and at freezing temperatures, it becomes more about your mental strength. But once you are at the top, all your pains will go in a jiffy. You will feel proud to be on top of the mountain pass.
The descent is however more difficult than the ascent. It is a steep and narrow 70 degree ice gully. Ropes are used to negotiate the descent. Once youreach at the bottom of the gully, a short walk will get you to your campsite.
Day 7: Khatling Glacier Camp – Zero Point (12 km)
This hike is also going to be technical and a challenging one. The day is going to be one of the longest and demanding as well. The walk is on the Khatling Glacier quite infamous for its deep crevasses. Ropes will again be used to trek this glacial stretch. After passing through the glacial stretch, you will arrive at the moraine trail. From here, the trail moves downhill until you reach the campsite for the day.
Day 8: Waterfall Camp – Chowki (8 km)
The trek is along the river valley for about 3 km and it will lead you to an open meadow. From here, another 5 km of trek will bring you to Chowki.
Day 9: Chowki – Masar Tal (8 km)
This day’s trek will also involve a lot of ascents, followed by a series of switchback descents. You will get beautiful view of the Thalay Sagar peak and the overlooking valleys. Some parts of the trail will be quite steep, but well defined till you reach Masar Tal. This will be your campsite for the day.
Day 10: Masar Tal – Mayali Pass – Vasuki Tal (12 km)
If you had though that the difficult days were over, you are wrong. This day’s hike also involves a strenuous ascent over boulders on a steep ridge to Masar Top. Then there is a little descent before climbing up the glacier again to the top of Mayali Pass. The descent from Mayali Pass is quite steep and technical, quite like that of the descent from the Auden’s Col. You might have to fix ropes and rapell. Continue your descent till you reach Vasuki Tal.
