Located 9.5 kilometers away from the trailhead, Huangma Suspension Bridge No. 1 crosses the Huangma River. An evergreen virgin broadleaf forest can be seen here all year round. Besides the trail, the rest of the area is not as accessible due to the high mountains and water nearby. There are not too many human activities, so the virgin forest has been preserved. The virgin broadleaf forest overgrown with bushes is a complete ecosystem in which various creatures have played indispensable roles in the area.
