Located in an isolated area at a 5 hr drive (160 km) from Leh, this 134 km long lake extends from India to China. Tourists mostly visit this lake during May to September with a special permit. The Pangong lake boasts of being the world's highest brackish lake at a height of about 4,250 m (13,900 ft) from sea level. Villagers can be seen with their large herds of Pashmina sheep and long-tailed yaks. Despite being a salt water lake, it surprisingly gets frozen in winter. With such a wonderful location and a scarcity of oxygen, the Pangong Lake is a geologist's domain too.
