I could not sleep well because of painful health issues in my calf, but my friends were sound asleep after the difficult summit attack the day before.

In Camp 3 New Hut, constructed in 2009 at 4250 m. above sea level by Iran Mount Climbing Federation.
It is one of the highest mountain huts in the world and the best place for acclimatization and accommodation in the area.

The New Hut contains comfortable hostel/lodge with private and common rooms with bunk beds.
It is open only in climbing season and not through the entire year. You should book a place in advance because it is crowded in climbing season.
