Pangong Tso's recent history is marked by its role as a disputed border between India and China. The lake became a major point of contention during the Sino-Indian War of 1962 and subsequent border disputes. Historically, the lake was part of a trade route between Ladakh and Tibet, frequented by nomadic communities and traders. Its strategic location has led to its militarization, with both countries maintaining a presence in the area. Despite the ongoing border sensitivities, the lake's breathtaking beauty has made it an increasingly popular tourist destination, attracting visitors from around the world.
