The Pin Valley National Park spreads over an area of 675 Km in the trans-Himalayan cold desert region of Spiti valley and falls in the catchment of the Pin River and its major tributary, Parahio. Altitude of the National Park ranges from about 3,500 metres near Ka dogri to more than 6,000 metres at its highest point.

Tucked in between the snow laden higher reaches and scree slopes covered with scanty tufted vegetation, Pin Valley National Park forms the natural habitat of a number of endangered animals including Himalayan Ibex, Snow Leopard, Bharal, Wooly Hare, Tibetan Wolf, and Snow Cock.
