1. Seoul: South Korea Demilitarized Zone Half & Full Day Tour
Journey to one of the most meaningful tourist destinations in the world at the Korean Demilitarized Zone (DMZ) on the border of South and North Korea. Gain an understanding of Korean history and culture. First, visit Imjingak Park. See the Bridge of Freedom, used by prisoners of war who were repatriated from the North. Next, head to the 3rd Infiltration Tunnel, an incomplete passage built by North Korea that runs under the Demilitarized Zone. Discovered in 1978, the tunnel passes through bedrock 240 feet (73 m) below ground. You can go inside the tunnel by foot. Once you're back on the surface, your guide will take you up the slopes of Mount Dora for a look across the country from the Dorasan Observatory. In good weather, you can see all the way to North Korea without using the observatory's telescope. Lookout at the 2.4-mile (4-km) stretch of the DMZ that has divided Korea since 1953 before you return to Seoul.
