Before I continued with the tour, here is the regulation.
DMZ, The Korean Demilitarized Zone is the buffer zone between North and South Korea, running across the peninsula along the 38th parallel.
The DMZ, a heavily militarized border. The DMZ is 250km long and about 4km wide.
We visited the 3rd Infiltration Tunnel which is one of the 10 tunnels built as an invasion route for the North Korea. So far, only 4 had been discovered. The 3rd tunnel is the most dangerous one because it infiltrated the deepest into South Korea. It is 1.95 meters high, 2.1 meters wide and 1,635 meters long. The tunnel penetrates 435 meters south of the military demarcation line (MDL) and ends at the Truce Village of Panmunjeom. The MDL goes down the center of the DMZ.
No photography is allowed in the tunnel. It is not an easy walk down the tunnel. Sometimes, we had to bend down and we often heard hard hat knocking the ceiling. Walking back up is also a challenge as it’s really tiring with the climb.
