Ladakh is a region of Jammu and Kashmir, the northernmost state of the Republic of India. It lies between the Kunlun mountain range in the north and the main Great Himalayas to the south, inhabited by people of Indo-Aryan and Tibetan descent. It is one of the most sparsely populated regions in Kashmir.
Historically, the region included the Baltistan (Baltiyul) valleys, the Indus Valley, the remote Zangskar, Lahaul and Spiti to the south, Aksai Chin and Ngari, including the Rudok region and Guge, in the east, and the Nubra valleys to the north.
Contemporary Ladakh borders Tibet to the east, the Lahaul and Spiti to the south, the Vale of Kashmir, Jammu and Baltiyul regions to the west, and the trans–Kunlun territory of East Turkistan to the far north. Ladakh is renowned for its remote mountain beauty and culture. It is sometimes called "Little Tibet" as it has been strongly influenced by Tibetan culture.
Ladakh is the highest plateau of the Indian state of Kashmir with much of it being over 3,000 m (9,800 ft). It spans the Himalayan and Karakoram mountain ranges and the upper Indus River valley.
Zanskar is a subdistrict or tehsil of the Kargil district, which lies in the eastern half of the Indian state of Jammu and Kashmir. The administrative centre is Padum. Zanskar, together with the neighbouring region of Ladakh, was briefly a part of the kingdom of Guge in Western Tibet.
The Zanskar Range is a mountain range in the Indian state of Jammu and Kashmir that separates Zanskar from Ladakh. Geologically, the Zanskar Range is part of the Tethys Himalaya, an approximately 100-km-wide synclinorium formed by strongly folded and imbricated, weakly metamorphosed sedimentary series. The average height of the Zanskar Range is about 6,000 m (19,700 ft). It's eastern part is known as Rupshu.
