What Makes Gurudongmar Lake So Special?
What makes Gurudongmar Lake special is how it sits surrounded by mountains on all sides, like nature built a perfect bowl to hold this crystal-clear water. On calm days, the mountains reflect in the lake so perfectly it is hard to tell where the real peaks end and their reflections begin.
Now, this lake is not just another pretty place – it is wrapped in stories and beliefs that make it special. People consider these waters sacred, each for their own reasons.
The story says that Guru Padmasambhava visited this area in the 8th century and found the lake frozen solid. The local people had no water. He touched part of the lake, and that spot never freezes, even in the coldest winter.
This unfrozen part still provides water to nearby villages. The area is filled with prayer flags, giving it a peaceful and holy vibe.
