The peninsula/island’s geology is rooted in the glacial volcanic lava landforms of the Quaternary period (a geologic time period that began approximately 2.6 million years ago). With an elevation of approximately 30 meters and an area spanning about 10,000 square meters, the island’s coastline plunges steeply into the sea.

The coastline, characterized by its rocky cliffs, exhibits an average depth of more than 40 meters, making it one of the deepest coastal areas in Hainan.
