Visit the third 'Tunnel of aggression" in Korea

The Third Tunnel of Aggression is one of four known tunnels situated within the Demilitarized Zone (DMZ) separating North Korea and South Korea, and it is one of the most famous "dark tourism" spots in the world. This place is located deeper than 70 meters beneath the ground and 265 meters long, and it is for sure a highlight of any DMZ tour!

The Third Tunnel of Aggression is constructed in the 1970s by North Korea when this country tried to separate itself from South Korea in an effort of denying the existence of the neighboring country. In fact, this tunnel is thought to be built for North Korea to launch a surprise attack on Seoul. Luckily, no attack occurred as South Korea was able to take control of the tunnel and clock off the demarcation line with the North via concrete barricades.

Despite being a famous tourist site that attracts many tourists, the Third Tunnel of Aggression is not a very safe place for visitors, because the tunnel passage is dark, long, and narrow, and it’s a steep incline to access it. The place is still being guarded even though there are some souvenir shops there. Taking photography is strictly forbidden once inside the site.
