Visit Shimen Cave: A Sea Arch Wonder

#MarchGoodPlaces2025 Shimen Cave, standing on Provincial Highway 2 on the Coastal Highway, is a prominent landmark in Shimen District, New Taipei City. The name comes from this Shimen Cave. According to legend, during the Japanese occupation era, the unique sea erosion topography of Shimen Cave amazed the Japanese and they named this place "Shimen Village", which later became the name of the local village and is still used today. [Geological Wonder] In topography, it is called "Sea Arch", which is an arch formed by erosion by sea water. Millions of years ago, the Datun volcano group erupted, depositing thick volcanic debris and lava. Later, heavy rains washed away and re-deposited layers of rock on the coast to form a small hill. The strata were then squeezed and cracked into vertical "joints", or cracks. The northeast monsoon and frequent typhoons in summer brought about waves and strong erosion energy. The rock layers collapsed into the sea piece by piece, and over time, the original sea trenches became sea caves, and finally evolved into the sea gates we see today. Walking into Shimen Cave, you can see the beautiful scenery of sea and sky, although there is only a small piece of beautiful shell beach here. The coastal reefs appear green because of the seaweed attached to them, and sometimes you can see local residents picking seaweed here. If you walk along the viewing platform and pavilion along the coastline, you can enjoy the vast sea view. 📍Address: 253 Central Road, Shimen District, New Taipei City
