Shimen Cave

Shimen Cave is a natural arch formation on Taiwan's north coast that rises roughly 10 meters (33 feet) above sea level with a prominent opening. The rock structure was carved out gradually by wave action and coastal erosion over countless years.

The stone arch once marked Taiwan Island's northern boundary and served as a navigation landmark for sailors crossing these waters for centuries. Erosion gradually reshaped the feature while it remained an important reference point for maritime activity in the region.

The area draws kite enthusiasts who take advantage of the strong ocean winds that blow consistently along the coastline. You can watch people launch their kites and enjoy the natural conditions that make this spot popular for their hobby.

The site is easily accessible by public transport and welcomes visitors year-round. The best time to explore the rock pools at the base is during low tide, when marine creatures become visible in the water.

The top of the arch still contains remnants of an old military gun position, revealing how this coastal spot was once used for defense. These hidden structures offer a surprising glimpse into the strategic military role the location once held.
