The trail gets more challenging today. We will start with a sharp ascent through boulders and scree to Sahastra Dhar. As we climb up the valley, views of NIlkanth, Balakun and Chaukhamba open up. Once we reach Sahastra Dhar, we will cross a little stream and walk across a flat area with dozens of streams flowing and merging with each other. Then, we start traversing the left (true right) lateral moraine of the glacier coming down from Chaukhamba at the head of the valley. The trail climbs steeply again after Sahastra Dhar, followed by a short level walk across the upper snow slopes to reach our campsite at Chakrateerth. We will camp in Chakrateerth for the night.
