Yuwan Scenic Area is located in the southeast of Yuntai Mountain where Huaguo Mountain is located. It is made up of waterfalls, cliffs and rock formations. The Hidden Dragon Cave in the middle of the mountain is an authentic water curtain cave. The cave can accommodate more than 20 people. When you stand close to the “Rainbow view platform” near the cave entrance and look out, you can see the huge rainbow reflection projected by the old Longtan Waterfall. The scene is absolutely spectacular.
