Reo Purgyil Base Camp Trek — Complete Guide (2026)
Introduction
Reo Purgyil (22,362 ft), also known as Leo Pargial, is the undisputed king of the Himachal Himalayas. Situated on the edge of the Zanskar range and the Tibetan plateau, this peak represents one of the most stark and otherworldly landscapes in India. The trek to the Reo Purgyil Base Camp is an expedition into a high-altitude cold desert, where the mountains are dry, the winds are biting, and the air is razor-thin. Starting from the ancient lake-village of Nako, the trail ascends through barren scree slopes and glacial moraines to reach a base camp that feels like the end of the world. This is not for the faint of heart; it is a serious undertaking for those seeking the ultimate high-altitude challenge in Kinnaur.
