East Coast National Scenic Area

Shimen Recreation Area is located 4 to 5 kilometers north of Shiti Fishing Port. Its name ("Rock gate") originated from the huge sea caves in the coastal reef area that are shaped like gates. The Hollywood film, Silence (2016), was shot here, making Shimen landscape known to the world.

Following along Provincial Highway 11 to Shimen Recreation Area, you can find parking space and trails built along the terrain. On the right, the trail leads to public toilets; the middle trail leads to the pavilion with sea view of the sea; and on the left the trail leads to the sea cave.

From Shimen Recreation Area to Shitiping and Gangkou Tribe, there is a reef coast stretching for several kilometers. The reef coast, which was originally a volcanic rock formation, has been eroded by waves for many years, developing a variety of geological wonders, such as sea caves, sea grooves, potholes, and sea terrace. The largest Shimen sea cave is 5 meters tall and 18 meters wide, with three openings. On top of one opening there is a giant large-leaved banyan tree. The sea-facing opening is called the "March Cave" as it looks like a March (a Nissan car model). Together with the sea groove facing the Pacific Ocean outside of the sea cave, this spot is now a must-see attraction for visitors.

When visiting Shimen Recreation Area, besides taking pictures at the March Cave and the beach, you can stand in the cave and listen carefully to the 3D sound effect of the whistling wind and pounding waves. In addition, carefully observe the vibrant coastal ecology here, especially the various seaweeds growing all over the reef coast, which is a paradise for fish and shrimp and a natural classroom for observing and learning about coastal creatures.
