1. The Third Tunnel of Aggression is one of four known tunnels dug by North Korea beneath the Demilitarized Zone (DMZ) that separates North and South Korea. Discovered in 1978, it is 1,635 meters long and 73 meters below ground. It is the most touristic tunnel open for tourists in South Korea. The tunnel was designed to transport North Korean troops for a surprise attack on Seoul. It is estimated that it could accommodate up to 30,000 soldiers per hour. Visitors can take a 265-meter hike through the tunnel, which is just 1.95 meters high and 2.1 meters wide. Due to its narrow size, visitors are advised to wear helmets provided by the tour company.

2. The Third Tunnel of Aggression is open seven days a week, except for some national holidays. The operation hours are from 9:00am to 5:30pm, and the last admission is at 4:30pm. Visitors are welcome to call the DMZ Tourist Information Center at +82-2-771-5596 for more information.

3. To enter the Third Tunnel of Aggression, visitors must join a DMZ tour, which can be arranged through authorized tour operators. The cost of the tour varies depending on the operator and itinerary chosen. Visitors are also required to bring their passport to validate their identity. Transportation to the DMZ is not included in the tour, so visitors must arrange their transportation separately. The tour bus departs from several designated locations in Seoul and may take 1-2 hours, depending on traffic.

Overview

More Info

The Third Tunnel of Aggression is one of four known tunnels situated within the Demilitarized Zone (DMZ) separating North Korea and South Korea. Located more than 70 meters beneath the ground and at 265 meters long, the Third Tunnel of Aggression is a highlight of any DMZ tour.The tunnel was built by North Korea in the 1970s, who initially denied its existence when South Korea discovered it later. The North were then said to have claimed it was a coal mine, before it was revealed that they had dug the tunnel in order to launch a surprise attack on Seoul. The South eventually took control of the tunnel, blocking off the demarcation line with the North via concrete barricades.Although the Third Tunnel is now very much a tourist site (there’s even a gift shop near its entrance), it still remains guarded and taking photography is forbidden once inside. The tunnel passage is dark, long, and narrow, and it’s a steep incline to access it.The DMZ can only be accessed via authorized shuttle buses and tours. There is also a dedicated monorail that serves the Third Tunnel area.
