The 2nd Tunnel - Cheorwon (제2땅굴 (철원))
The 2nd Tunnel, which was made by North Koreans to invade South Korea, was discovered on March 24, 1975. This tunnel is 3.5 kilometers long and sits 50~160 meters below the surface. It stretches out 1.1 kilometers and 2.4 kilometers in the south and north directions respectively. Only 500 meters is open for tourism among the whole length. Inside of the tunnel, there is a plaza to gather a large military force. The tunnel is divided into 3 exits. The use of this tunnel would allow for thirty thousand armed forces as well as tanks to pass through per hour. For now, the tunnel is operated as part of Cheorwon Security Tourism Course and many tourists visit this area every year.
