The 'Drang-Drung Glacier' (also called Durung Drung Glacier) is a mountain glacier situated near the Pensi La mountain pass at the Kargil - Zanaskar Road in Kargil district of Jammu and Kashmir in India.
The Drang-Drung Glacier is likely to be the largest glacier in Ladakh other than Siachen Glacier in the Karakoram Range, with a maximum length of 23 kilometres (14 mi) and at an average elevation of 15,680 ft (4,780 metres). The glacier lies in the north eastern Himalayan Range known as Zanskar Range, situated 142 kilometres (88 mi) south from Kargil and 331 kilometres (206 mi) east from Srinagar the capital of Jammu and Kashmir.
The Drang-Drung Glacier is the long river of ice and snow, a source of Stod River which is a tributory of Zanskar River and Zanskar River is a tributory of Indus River. The Doda Peak with an elevation of 21,490 ft (6,550 metres) rises from the glacier.
The Drang-Drung Glacier is accessible from Srinagar or Srinagar Airport in two days, 331 kilometres (206 mi) of drive by car or bus which leads by NH 1D, a national highway which connects Srinagar and Leh through the towns of Ganderbal, Kangan, Sonamarg and Dras. Kargil town is at the half way distance and a feasible place for a night halt. From Kargil the glacier lies on the right side of Kargil-Zanaskar Road which passes through a gorge valley of Suru River and under the shades of two mountain peaks of Nun and Kun. After crossing the Pensi La mountain pass a trekking of one day from the road leads to the head of Drang-Drung Glacier. The road is only open for traffic from the month of May to September due to heavy snowfall at Zojila and Pensi La passes, and the best time to visit is July to August.
