Pangong Tso is a high-altitude lake in Ladakh with salty water due to minerals dissolved from surrounding rocks. It doesn’t drain into any ocean or sea, so minerals accumulate over time, making the water salty unlike most freshwater Himalayan lakes.

Pangong Tso, located in Ladakh, is an endorheic lake, meaning it doesn’t drain into any external water body. Instead, it collects mineral-rich water from surrounding mountains. Over time, due to evaporation and lack of outflow, these minerals get concentrated in the lake, making its water salty. Unlike glacier-fed freshwater lakes, Pangong Tso is fed mainly by snowmelt and runoff, allowing salts to build up. Its unique chemistry and striking blue colour attract scientists and tourists alike.
