Situated at the northeasternmost side of Hong Kong, Ping Chau is composed of sedimentary rocks. The island generously showcases the ancient skeleton of the Earth in a way that it serves like a geological museum. Enclosing the island of Tung Ping Chau and occupying a sea area of 270 hectares, Tung Ping Chau Marine Park is home to the most diverse species of coral communities locally. Skirting along Ping Chau, Ping Chau Country Trail features a multitude of landform wonders such as Kang Lau Shek, which stands bold and still on the east seashore and two gigantic sea stacks that are 7-8 metres tall. Kang Lau Shek, together with the two sea stacks, looks like a look-out that was built for protecting the island long ago. A closer look at the stacks will reveal their shale lamination. On the southernmost side are wave-cut platforms that are extended from the cliffs. These platforms are named so because the area is not accessible at high tide. Not far away lies a 100-metre sedimentary rock emerging from the sea. It is called Lung Lok Shui because its spiky edges caused by erosion resemble the back of a dragon. Towards the end of the route is Cham Keng Chau, which broke off because of years of wave erosion. Attentive observers will notice the walls of villages on the island are built of shale formed millions of years ago.
