The unique geological landscape of Siaoyeliou is a result of inverted sandstone and mudstone layers. After a geological structure change,the gigantic sandstone shale became upside down and covered with coral reef. After years of sea erosion,a unique geological form was developed. Amazing rocky formations are found on the trail,such as shapes of a mushroom,tofu,and coral reef. The geological exhibition hall at the Tourist Service Center provides further information of geological formations and land features unique to the area. The broad grass land of the Jialulan Recreation Area at the north is decorated with art fixtures of primitive-looking driftwood. The area is ideal to gaze into the night sky and listen to nature's concerto of tides.
