The North Korean border is a day trip from Seoul, South Korea. The demilitarized zone buffers the border between South Korea and the hostile isolated nation of North Korea. Despite the escalating threats from the North, tourists can go to the edge of the DMZ and transfer onto special buses escorted by United Nations soldiers. Using coin-operated binoculars at the Dora Observation Post near the border village of Panmunjom, you can stand on a platform and look across the DMV expanse and into North Korea. No cameras allowed. It’s unnerving, but you come away with a deep appreciation of the simmering hostility.
