If you are interest about the history of North Korea invasion to South Korea in 1950 and armistice in 1953, you have to take this tour.
DMZ and Joint Security Area are a must to visit. Tunnel 3 let you know North Korea always want to invade South Korea. Recently
the tension is quite immense. Remember this is NOT a sightseeing place. At the end there are 15 minutes for souvenir shop. If possible
better to the museum in the second floor, worthy a visit.
