Second Infiltration Tunnel (제2땅굴, Closed every Tuesday 매주 화요일 휴무)The Second Infiltration Tunnel (제2땅굴) in Cheorwon is an infiltration tunnel discovered in 1975 in Hwasaljang-ri, Cheorwon-gun, Gangwon-do (강원도 철원군 화살장리), intended for a southward invasion. The total length is 3.5 km, extending 2.4 km north to south and reaching 1.1 km from the Military Demarcation Line (군사분계선). It is large enough to move approximately 30,000 troops per hour. Of this, 500 meters are open for visitors. Inside the tunnel, there is a large plaza capable of accommodating a significant number of troops, and the exits branch into three directions. At the time the Second Tunnel was discovered, seven South Korean soldiers (한국군 7명) searching the area were killed by North Korean forces. The Second Tunnel has been developed as one of Korea’s representative security tourism sites in accordance with the Iron Triangle Battlefields Development Plan (철의삼각전적지 개발 계획), and many visitors come each year. Inside the Second Tunnel, there is an exhibition hall that explains the structure of the tunnel and North Korea’s invasion plans. The view of the DMZ seen from the Second Tunnel, which symbolizes the division between North and South, is exceedingly beautiful.

It is currently operated by the Cheorwon County Office (철원군청) as part of the DMZ Peace Tourism course, and in addition to the Second Tunnel, there are various nearby attractions such as the Cheorwon Peace Observatory (철원평화전망대), monorail cars (모노레일카), and the Cheorwon Crane Museum (철원 두루미관).
