Even though it is no longer wartime and there is no longer a lot of military on the island since the young soldiers have gone, there are still numerous special wartime attractions for the traveler to see there. The Jiugong Tunnel is one of the most spectacular wartime attractions in Jiugong.
From the Kinmen Pier take a ferry to the Little Kinmen Jiugong Pier and only walk a short distance to the entrance of the Jiugong Tunnel. The tunnel is also called the Siwei Tunnel because it connects Jiugong and Siwei. It was built in a double J configuration and was important in the defense of the Jinlei waterway.
