Gephan Peak (20,945 ft) is the highest peak in the Lahaul district and the presiding mountain deity of the Lahaul and Spiti valleys. The base camp trek at 16,200 ft is a serious 6-day high-altitude approach through the remote Miyar Valley, offering extraordinary glacier views and proximity to one of Himachal's most revered sacred mountains. The base camp sits in a dramatic cirque of ice-clad peaks rarely photographed by the outside world. A highly authoritative approach for the most serious trekkers.
