For climbing of Pastore Peak from base camp to summit it will take 10 to 12 hours(Base camp to summit only), depending of the fitness, expereince of the climbers. The Concordia is junction of highest peaks on earth. There are cluster of peaks around concordia. Pastore peak is famous for its easy climb. It is very difficult for me to decribe the climb, because I have not climbed this peak, however my friends/guest who has climbed this peak or tried this peak can decribe its climb well.
