Pangong Lake
Explore the area around Pangong — visit Lukung village's traditional Ladakhi stone houses, the ancient Spangmik monastery overlooking the lake, and the viewpoint where the India-China Line of Actual Control (LAC) runs through the lake, dividing it between India and China.
You can go up to the LAC marker at Pangong — beyond which is China-administered territory. Photography is permitted but no crossing is allowed.
