The Third Tunnel
停止: 30 minutes
Descend into the Third Tunnel of Aggression, also called the 3rd Infiltration Tunnel, a chilling relic of North Korea’s covert plans, uncovered in 1978. Located just 52 km from Seoul and 12 km from Munsan, this 1,635-meter-long passage—2 meters high and wide—could funnel an entire division per hour for a surprise invasion. When discovered, North Korea claimed it was a South Korean plot, but dynamite marks and slanted drilling proved otherwise. Walking its damp, narrow depths feels like stepping into a Cold War thriller. Sense the eerie weight of history as your guide recounts its discovery by a defector’s tip. If tight spaces aren’t for you, relax near the exit. This stop on your group DMZ tour from Seoul is a heart-racing highlight, blending danger and discovery.Read moreMore about The Third Tunnel
