Spanning 248 kilometers across the 38th parallel, the Korean Demilitarized Zone (DMZ) stands as the last remaining frontier of the Cold War. Visitors can peer into North Korea from the Dora Observatory or descend 73 meters underground into the secret 3rd Infiltration Tunnel.
Find Guided ToursThe Korean Demilitarized Zone (DMZ) is a 248-kilometer-long and 4-kilometer-wide buffer zone separating North and South Korea. Established on July 27, 1953, under the provisions of the Korean Armistice Agreement, it was created to cease hostilities of the Korean War. The zone acts as a physical barrier across the 38th parallel, extending exactly two kilometers on either side of the Military Demarcation Line.
Despite its name, the DMZ is the most heavily fortified border in the world. It is lined with landmines, barbed wire, and active military personnel. However, the strict prohibition of human habitation over the decades has inadvertently transformed the landscape. Today, the restricted area functions as one of the most pristine temperate ecological sanctuaries in Asia.
The zone remains globally recognized as the last frontier of the Cold War. It serves as a site of intense geopolitical significance where the two Koreas remain in direct confrontation. This tension is most visible at the Joint Security Area (JSA), an 800-meter-diameter compound where soldiers from both nations stand face-to-face. The JSA has been the focal point of major historical events, ranging from the 1976 Axe Murder Incident to the historic 2018 Inter-Korean Summit.
Beneath the surface, the history of conflict continues. North Korea secretly dug multiple infiltration pathways beneath the border, with four tunnels discovered to date. The 3rd Infiltration Tunnel, found in 1978, sits 73 meters underground. Measuring 1,635 meters in length, military engineers designed it to move up to 30,000 soldiers per hour.

Walk 73 meters underground into a secret military passage discovered in 1978. The damp, steep pathway stretches for 1,635 meters. North Korea originally designed this covert route to move up to 30,000 soldiers per hour beneath the heavily fortified border.
