The Yanyan Scenic Area is located in the Qiaotou Town, at the southwest of Huaiji County, 27 kilometers away from the county seat. It is a typical Karst cave, named Yanyan because countless golden swallows build nests and breed here. The scenic area consists of more than 360 stone peaks that rise up from the ground with different divine appearances and more than 170 caves with different sizes, presenting a typical Karst landform. It is known as "Small Yangshuo". The Yanyan Scenic Area has beautiful mountains and peaks with peculiar shapes, forming natural landscapes. Except enjoying the beautiful natural scenery of Yanyan, you can also watch the thrilling feats of people collecting swallow's nest climbing cliffs and walking on walls.
