Munigou Valley still is located at The Huanglong Scenic and Historic Interest Area. Holding the primary area of virgin forest, the Muni Valley comprises Erdao Lake and Zhaga Waterfall which is the biggest calcified waterfall in all China.

Erdao Lake (Erdao Hai)
Located in the northern part of Muni Valley, Erdao Lake is the largest in the area and around the lake are many underground limestone caves which connect Erdao Lake with other lakes in the area. The color of Erdao Lake varies with the seasons, harmoniously complementing the lake with its surrounding of colored limestone. When standing by the lake, it seems very tranquil and calm; this belies a strong undercurrent that is very active. Erdao Lake holds attractions such as Swan Lake, Baihua Lake, etc. Beside the Baihua Lake, there is a mysterious cave which embraces wonderful and magnificent naturally-formed stalactites. One of Songpan horse trekking will take you to this scenic area. An admission fare is 70 RMB.

Zhaga Waterfall
Zhaga Waterfall scenic spot stretches for about 5 kilometers, where water flows around trees and trees grow in water and this scenic spot boasts many attractions. At the bottom of Zhaga Waterfall, there is a round-shaped stone onto which the waterfall cascades. In the sunlight, the spattering water is like jade, exhibiting wonderful colors. This is the Jianyu Tai (spattering jade platform). Guhuashi (ancient fossils) is the place where a number of prehistoric, fossilized animals, plants and fish are well preserved and remain intact. Feicui (Emerald) Spring is one of the ten most famous springs in China due to its water抯 medicinal value, and many have recovered from stomach sickness and arthritis after drinking or bathing in its water. The local population considers Feicui spring divine and allows nobody to cause damage. Winter Jiuzhaigou tours will involve this place instead of Huanglong Park.
