Lingti Valley is the longest side valley in Lahaul and Spiti District. It runs north-east from Lingti village for about 60 km to its head.
The geological history of the place dates back to 250 million years. The fossil findings in the place have lead to the development of many geological theories. Gaya Peak, the highest peak in Himachal Pradesh, is situated high above the northern head of the valley. The peak is the meeting point of Spiti, Ladakh and Tibet.
