Two-Bridge (Shuangqiao) Valley is the most easily accessible valley with vistas of snowy peaks, pastures, grassland and forests. It is the most beautiful valley of Mt. Siguniangshan. With three sections covering an area of 216.6 square kilometers (about 83.6 square miles), the whole valley is accessible by tour bus. It's the easiest and quickest way to see the valley because of the amount of distance and the ruggedness of the terrain. People visit this valley primarily for convenient nature sightseeing.
The first section contains some unique sights including Willow (Yangliu) Bridge, Yinyang Valley, the White Poplar Zone, Sun-Moon Mirror Mountain (altitude15, 747 feet) and Five Colors (Wuse) Mountain (altitude14, 673 feet). Yinyang Valley extends 2 kilometers (about 1.2 miles), and occupies the area near the entrance to Willow (Yangliu) Bridge. Out of the narrow ravine and steep cliffs a brook flows quietly. Entering the valley, the bright sunshine is suddenly disappears. If you raise your head and look up, you can only see a sliver of sky. Sun-Moon Mirror (Riyue Baojing) Mountain stands next to Five Colors (Wuse) Mountain. A huge rectangular boulder split in two on the snow-capped mountaintop looks like two bright mirrors hanging over the horizon. Five Color (Wuse) Mountain is the most spectacular sight in Two-Bridge (Shuangqiao) Valley. The mountain is made from five colors of rock: red, yellow, green, blue and white.
In the middle section is the Driven fish (Nianyuba) plank road built along a cliff and the Shaji woods (Lin). Shaji is a small golden fruit, which is called the 'King of vitamin C'.
In the last section are marvelous rock sculptures carved naturally by the wind. You can see wonderful shapes resembling an ape, a hunter, or a hawk beak. More than ten snowcapped mountains above 4,000 meters (about13, 122 feet), make the area a favorite with climbers.
