Pangong Tso is the Himalayan lake lying at about 4,350 metres along the India–China border.
The elongated lake extends from Ladakh in India into Tibet, which is administered by China. Its name comes from Tibetan and is commonly translated as “high grassland lake.” The lake is more than 130 kilometres long, but only part of it lies in India.
Pangong Tso is saline or brackish despite being a high-altitude lake, and it freezes during winter. Its striking blue water and barren mountain setting have made it a prominent destination in Ladakh.
The lake’s location also gives it strategic importance. The disputed boundary passes through the region, so access and military activity have changed over time. It should not be confused with Tso Moriri, another major high-altitude lake entirely within Ladakh.
