When Tibetan people in pilgrimage to worship at a holy lake, they never forget to sincerely pray next to the Ghost Lake.

The "Ghost Lake" La-nga Tso is very close to the side of the holy lake Mapam Yumco. La-nga Tso Lake is a beautiful blue crescent-shape lake, while Mapam Yumco takes on the shape of the sun.

The two lakes are not far from one another and connect by water. The water of the holy lake is pure, cold, sweet and clear. The water of the Ghost Lake on the other hand is bitter and hard to swallow. This demonstrates the state of harmony between the two lakes.
