Pangong Tso, Tibetan for "long, narrow, enchanted lake", also referred to as Pangong Lake, is an endorheic lake in the Himalayas situated at a height of about 4,350 m (14,270 ft). It is 134 km (83 mi) long and extends from India to Tibet. 60% of the length of the lake lies in Tibet. The lake is 5 km (3.1 mi) wide at its broadest point. All together it covers 604 km2. During winter the lake freezes completely, despite being saline water.Pangong Tso can be reached in a five-hour drive from Leh, most of it on a rough and dramatic mountain road. The road crosses the villages of Shey and Gya and traverses the Changla pass, where army sentries and a small teahouse greet visitors. Road down from Changla Pass leads through Tangste and other smaller villages, crossing river called Pagal Naala or "The Crazy Stream". The spectacular lakeside is open during the tourist season, from May to September.An Inner Line Permit is required to visit the lake as it lies on the Sino-Indian Line of Actual Control. While Indian nationals can obtain individual permits, others must have group permits (with a minimum of three persons) accompanied by an accredited guide; the tourist office in Leh issues the permits for a small fee. For security reasons, India does not permit boating.
