The DMZ, or demilitarized zone, is the boundary area between North and South Korea. It is considered a cease-fire zone. While travelers can visit the DMZ, not all areas of the zone are safe. Only a small portion of the DMZ, known as the JSA or Joint Security Area, is open to the public.
The Korean Demilitarized Zone is a strip of land running across the Korean Peninsula near the 38th parallel north. The demilitarized zone (DMZ) is a border barrier that divides the Korean Peninsula roughly in half.
It was established to serve as a buffer zone between the countries of North and South Korea under the provisions of the Korean Armistice Agreement in 1953, an agreement between North Korea, China and the United Nations Command.
The DMZ is 250 kilometres (160 miles) long and about 4 kilometres (2.5 miles) wide. There have been various incidents in and around the DMZ, with military and civilian casualties on both sides. Within the DMZ is a meeting point between the two nations, where negotiations take place: the small Joint Security Area (JSA) near the western end of the zone.
In the JSA, you can physically stand in North Korea, although you will be within a building that also houses South Korean soldiers. You can also visit a North Korean gift shop that sells stamps, wine, and currency from North Korea. Be aware that the only way to visit the DMZ is on an authorized and guided tour.
