Coral Lotus Wall Introduction: At the foot of the cliff on the left side of the river valley, there is a naturally formed lava rock wall hanging, which is the "Coral Lotus Wall". The local people call it "Lotus Terrace". The wall is about 10 meters high and 12 meters wide. Various flowers with branches and leaves protrude from it, forming a beautiful pattern, like a huge picture frame inlaid on the stone wall. From a distance, it looks like a coral reef in various shapes, and up close, it looks like a blooming lotus, which makes people marvel after watching it.
