I camped solo, by the Pangong Tso (Ladakh, India) and survived… well, not just survived, but came back with an experience that I will cherish for the rest of my life. Totally incredible! Over 4200 meters above sea level; temperature well below freezing (it was 4 degrees inside the tent at 5:30 in the morning). And there I was camped on a peninsula in one of the biggest and bluest lakes in the country, with water splashing on all three sides (wind creates almost see like waves) and the tent fluttering in the wind all night. Didn’t get much sleep. Not just the noise and cold, but also the night sky, and then the dawn.
Highly recommend this lake. Must do once in your life, especially before the lake gets commercialized… I can see early signs of that happening.
