Spiti, pronounced as "piti" in the Bhoti language, is a high-altitude region of the Himalayas located in the northeastern part of the northern Indian state of Himachal Pradesh. The name "Spiti" means "The middle land," referring to the land between Tibet and India. Spiti primarily encompasses the valley of the Spiti River, along with the valleys of several rivers that feed into it. Some of the prominent side valleys in Spiti are the Pin Valley and the Lingti Valley. Spiti is bordered on the east by Tibet, on the north by Ladakh, on the west and southwest by Lahaul, on the south by Kullu, and on the southeast by Kinnaur. The region has a cold desert environment and is among the least populated areas of India. The Bhoti-speaking local population practices Tibetan Buddhism.
