Chenggong Cave/Chenggong Beach Introduction
The Chenggong Tunnel, carved from granite, is located in front of the popular attraction Chen Jinglan Western-style Mansion. It combines the functions of a coastal tunnel and a civil defense tunnel. Compared to other tunnels in Kinmen, the Chenggong Tunnel is smaller in scale but is equipped with a command center, anti-aircraft artillery positions, high-caliber artillery positions, machine gun bunkers, dormitories, and kitchens, all of which served significant purposes during wartime. Currently, various life-size statues are set up to simulate past defense scenes, and an M-41 tank is parked nearby for close viewing. The tunnel stretches 560 meters, with Zhongxing Pavilion marking the boundary on both ends; the seaside section is controlled by the military to monitor the situation in Liaoluo Bay, while the other end connects to the Zhengyi Village Office, providing a refuge space for residents, perfectly embodying the atmosphere of kinship between military and civilians in Kinmen's past. Today, the Chenggong Tunnel and the beach have shed their wartime solemnity, with the blue sea becoming one of Kinmen's most popular summer swimming spots! The phenomenon of "blue tears" occurs from April to June each year due to changes in wind direction and temperature, with Kinmen's waters often showcasing this beautiful scenery. Chenggong Beach, being easily accessible and safe, is an excellent place to observe the blue tears! ◆ Tips for Observing Blue Tears ◆ ◼️ Season: From April to early June each year, during the transition from spring to summer (this is the fog season, so please pay attention to flight conditions). ◼️ Time: Around the third day of the Lunar New Year (when the moonlight is weaker), 1-2 hours before high tide. ◼️ Wind direction: South wind. ◼️ Suggested equipment: Shoes with anti-slip functionality, and you may also bring a flashlight or headlamp (for finding the way; please turn off the lights when observing the blue tears). ◼️ Photography tips: Use a professional camera and tripod, set the ISO to 800-1,000, aperture at 2.8, and white balance above 3,000K, with an exposure time of 30 seconds.
