Munigou Valley is located in Moni Town, southeast to Songpan City, occupying an area of 160 square kilometers with an average altitude of 2800 meters. The annual average temperature at this area only goes to 4ºC. Peaks, caves and lakes coexist and enrich each other. Most of the lakes there have the same beautiful scenery as Jiuzhaigou. The calcified waterfall is as splendid as in Huanglong. Nowadays, Zhaga waterfall and Erdaohai are opened to the public.
Tourists can drive one hour to Zhaga Waterfall from Songpan or can ride a horse there which is more exciting. As for Erdaohai, only horses can take tourists there.
Zhaga waterfall is a layered waterfall with a width of 35 meters and a height of 104 meters, which is regarded as the highest calcified waterfall in China. The dropping speed of the water is about 23m /second, and it roars the whole valley. You can walk and ascend slowly passing by some scenic spots. When you reach at the magnificent waterfall at last, you can appreciate the whole view of it.
Erdaohai means two lakes, situated at the end of Munigou Valley, separated from Zhaga waterfall by a mountain. The name of Erdaohai is derived from two lakes, Dahaizi and Xiaohaizi. Erdaohai is actually a long narrow valley, 5 km long, running through by a wood plank road. While walking into it, you can see a series of lakes one after another with crystal clear water. Wild flowers and green branches are reflected on the lake surface, it just looks like an oil painting. At the deepest end of the valley lies a hot spring with the legend that fairies from the heaven once bathed there. The temperature of its water is about 25ºC with a strong smell of sulfur. People like to bath here to cure or prevent skin disease.
