Nubra, also called Dumra, is a historical region of Ladakh, India that is currently administered as a subdivision and a tehsil in the Leh district. Its inhabited areas form a tri-armed valley cut by the Nubra and Shyok rivers. Its Tibetan name Dumra means "valley of flowers". Demands have been raised and BJP has hinted at creation of Nubra as a new district. Diskit, the headquarters of Nubra, is 120 km north of Leh, the capital of Ladakh.
The Shyok River meets the Nubra River (or Siachan River) to form a large valley that separates the Ladakh and Karakoram Ranges. The Shyok river is a tributary of the Indus river. The average altitude of the valley is more than 10,000 feet (3,000 m) above the sea level. The most common way to access this valley is to travel over the Khardung La pass from Leh.
