Pin Valley, in Lahaul and Spiti District, is situated on the either banks of the Pin River. High mountains isolate the valley and the only opening being a deep narrow gorge formed by the gushing Pin River. Compared with the main Spiti valley, the Pin valley is more barren and rugged.
The valley is renowned for the internationally recognized Chaumurti horses. They are sold on a large scale during the Lavi fair. Most popular activities in the valley are horse racing and arrow shooting.
Pin valley is connected with the Kinnaur District through the 'Shakarof Pass' or 'Tarikhango pass'. Kullu valley can be reached by crossing over the Pin Parbati peak. The entire Pin valley, inclusive of its villages, now forms a protected area, at an altitude ranging from 3,600 to 6,632 meters above sea level.
