Antong Tunnel Introduction
The Andong Tunnel is a must-visit military attraction in Dongyin, featuring a long staircase. This massive combat tunnel was carved through Erchong Mountain, the location of the Dongyin Command, and was constructed around 1971 during the Cold War. The military released the tunnel to the public in 2002, and it was renovated by the Matsu National Scenic Area Administration, officially opening to visitors in 2004. The entrance to the tunnel is adorned with a camouflage exterior, located next to the training class. Upon entering, visitors descend a steep slope and approximately 464 stairs, leading into the branching, cave-like, complex underground structure of the Andong Tunnel. The Andong Tunnel, which cuts through Erchong Mountain, is about 300 meters long and features eight passageways along the corridor, including rooms for the squad leader, dormitories of different sizes, a command room, an ammunition depot, a washing room, and even a pigsty, all connecting to the seafront. The observation holes are positioned on the cliff's edge, once serving as gun ports, and now provide an excellent viewpoint for enjoying the sea, seagulls, and the fjord. Visitors can look out and see rock formations named "Indian Head" and "Puppy Head," making it worthwhile to explore this area. The various constructions within the tunnel have been restored, adding significant tourism value. Around April each year, protected bird species like black-tailed gulls and sand martins migrate from Japan to nest and breed in the tunnel entrance and surrounding reefs. From the observation platform, the blue sea, clear sky, strange rock formations, and flocks of seagulls create a breathtaking scene. Every summer, this site attracts many bird lovers. Notes: 1. A complete visit takes about 30-60 minutes, and the tunnel stairs are steep; be prepared to climb back up. 2. Please turn the lights on and off when entering and exiting the tunnel, which is steep; vehicles are not allowed inside! 3. Sand martins are highly sensitive to noise; please speak quietly while birdwatching in the Andong Tunnel to avoid disturbing them.
