Introduction
The Northern Coast Bitou – Longdong Geopark attracts scientists and tourists with its abundant geographical resources. Developing from an area of sunken land on the coast of South China that was then pushed up from the seas into a mountainous island, the Northeast Coast is in fact a miniature projection of Taiwan. A period of great changes and fierce evolutions has carved itself into Longdong Cape's ancient and adamant sandstone walls, and recorded itself into Bitou Cape's sediment beds.
The area around Bitou Cape and Long Dong is a sea cliff sticking out to the northeast. The Long Dong Cape spurts into the sea and forms a headland because it is composed of hard sandstone. Various marine processes, cross-bedding and differential erosion contribute to creating the uniqueness and diversity of landscapes. Bitou Cape is one of the Three Capes of North Taiwan with the others two being Fugui Cape - the island's northernmost cape, and Sandiao Cape (Sandiaojiao) - the easternmost cape. Most of the sea-eroded landform types of the entire Northeast Coast are found here, including the sea cliffs, undercut bluffs, and platforms which are more fully developed here than anywhere else in Taiwan. The sea-eroded platforms are thick with mush-room-shaped rocks, honeycomb rock, tofu (bean curd) rock, and marine fossils, all of which make this an outstanding natural geological classroom.
The Longdong Bay Cape Trail not only links up the two largest capes of the Northeast Coast, Bitou and Longdong Capes but also has bridged the gap between two different geological eras, one that took place six million years old and the other occurred 35 million years ago. Hiking along the three-km long trail is like strolling through time and space. With every step taken, you shall become more interested in the earth’s history.
