The bay encompasses a half-moon shape beach for around 1 km length long. Due to its location close to the most northwestern point of Taiwan Island, the area is very windy. During the low tide, the beach area becomes very large, sometimes over 200 meters deep with shallow tide pool and many sand bars. Different minerals present in the rock around the beach have created a mottled rock surface where it has created primitive fish traps made of heaped landslide and broken coral, where fish are stranded by the retreating tide.
