The Zechawa Gully, 18 kilometers long, stretches from Nuorilang to the Chang Lake, the route of the highest altitude of all your Jiuzhaigou tours, featuring overlapped and erecting peaks. Overlooking from a distance, you will have a full view of the U-shaped valley, under the sun and covered with glaciers. Looking afar from Mountain Duona, you will find tranquil snow peaks and meandering mountain ranges, as if you were touring around in the universe.
