The only cave in Korea to use a train to view the inner side of the tunnel, the 4th tunnel

韩国唯一，利用观赏用电动车可以观赏洞窟内部的第4洞窟

 
The 4th Tunnel was discovered on March 3, 1990. It is located 1,200m from the Military Demarcation Line in the demilitarized zone of South Korea. This is the only tunnel to be discovered that provides full access to tour groups. Educational instruction is given in the square outside the tunnel. Around the entrance, there are many safety centers and monuments including military equipments. Among them all, the most noticeable is the statue of the military dog, ‘Hunt’. Hunt is an investigatory dog that died during the process of exploring the 4h tunnel. It saved the life of a squad, in which it stepped on a North Korean mine. There are no ranks for military dogs, but Hunt was declared as a lieutenant by his death. The safety education center has a theatre and exhibition hall with a capacity of 200 people. Plus, the 3D projector featuring the North Korean tour sites enables easier understanding of North Korea.

1990年3月3日被发现的第4洞窟，是韩国唯一利用观赏用电动车，观赏洞窟内部的地方。杨口东北方26公里地点的DMZ内被发现的这个洞窟，离军事分界线仅仅是1.2公里之处。入口周围包括军用装备，还有纪念碑与安保教育馆，其中最显眼的就是军犬‘Hunt’的铜像。Hunt是第4洞窟追踪过程中死去的嗅探犬，踩到北韩埋设的地雷而献出生命，救出了1个分队军人的宝贵生命。军犬本来没有军衔，但承认该功劳，追封为少尉，并在第4洞窟前竖立铜像，纪念该功劳。安保教育馆备有可以同时容纳280多名的电影院与展示馆，将北韩的观光地记录在交卷的三维立体摄影机安装在休息厅，提高对北韩的理解。
