What Travellers Say
Reviews Summary
Visitors find the Third Infiltration Tunnel a profound and sobering experience, offering a tangible connection to the Korean War's legacy. While the physical challenge of the tunnel is noted, most agree it's a worthwhile, albeit optional, part of a DMZ tour. The educational value and historical significance are consistently praised, though some find the tour logistics or potential for cancellations frustrating.
"We went to the 3rd infiltration tunnel as part of our DMZ tour. As the bus takes you to the tunnel, you cross an innocuous blue line painted on the road. This marks the start of the DMZ.
At the 3rd tunnel there is large carpark with an old tank, museum and some sculptures at one end and the entrance to the tunnel at the other.
When you enter the building housing the tunnel entrance there is a photo opportunity with some much guards. You then have to deposit your mobile phones as they cannot be taken into the tunnel. You then have to collect a safety hat which turns out to be a vital piece of kit. Don’t take it off!
Now for the fun part(!) - the walk to the tunnel is 350 metres down a steep walk. Then you walk along the tunnel itself for 250 metres until the first (of three) concrete blockades; you cannot go further than the first blockade which is actually only about 170 metres from the border with North Korea.
The walk along the tunnel is quite low in many places - I am 6 foot tall and spent 80% of the 250 metre walk bent over and hit my head on the jagged roof at least a 8-10 times. I was very grateful for the hard hat.
The tunnel has a number of area with dynamite holes made by North Korea and the tunnel is a nice piece of history. But other than that, there is not much to see.
Then you have to walk back along the tunnel for 250 metres half bent over before the 350 metre steep climb back to the top. So make sure you have comfortable walking shoes and are prepared for the walk - I was reasonably ‘puffed’ by the time I reached the top and the souvenir shop."

"Kudos to the management !! This place is beautifully managed. Going inside The Third Tunnel is unique exciting experience. Sports shoes are must, as you need to walk almost a mile inside the tunnel, wet surface. Outside the tunnel, there are many picturesque points to capture memories and spend quality time. Cafeteria and shopping is also available. If you are in South Korea, DMZ is must go !!!"

"Fascinating and intense part of the DMZ experience
The Third Infiltration Tunnel is one of the most interesting and memorable parts of any DMZ tour, a must-see if you’re exploring the area. Just a heads-up: you can’t visit on your own, so make sure to book a guided tour in advance.
The experience begins with staff giving you helmets for safety (you’ll need them!), and then you walk down a steep ramp (about 350 meters) into the tunnel itself. It’s deep underground, and the tunnel is narrow and low in places, so it’s definitely not ideal for anyone claustrophobic. The tunnel leads to a sealed-off area that was once part of a planned infiltration route from North Korea, making it historically significant and eye-opening.
Unfortunately, photos are strictly not allowed inside, so you’ll have to rely on memory, but it’s an experience that sticks with you.
The outside area is peaceful and surprisingly scenic, offering a nice contrast to the intense history underground. You can walk around, enjoy the views, and take photos here.
Highly recommended as part of a full DMZ tour.

For Different Travelers
Tailored advice for your travel style
👨👩👧 Families with Kids
Many DMZ tours include other attractions like Imjingak Park and the Freedom Bridge, which are more accessible and engaging for children. These areas offer historical context without the physical intensity of the tunnel. If you decide to enter the tunnel, assess your child's comfort level and be prepared to turn back if they become distressed.

Understanding the Third Infiltration Tunnel
Visitors often describe the experience as sobering and eye-opening. The narrow passages, low ceilings, and steep incline are designed to evoke the difficult conditions faced by infiltrators. While optional, many feel it's a crucial part of understanding the history and current geopolitical situation. The tunnel's construction is a testament to the lengths North Korea went to in its attempts to undermine the South.
It's important to note that photography is strictly prohibited inside the tunnel for security reasons. Visitors are usually asked to leave their cameras and phones at a designated locker area before proceeding. This measure underscores the sensitive nature of the location and the ongoing military presence.
Navigating DMZ Tours and Logistics
When booking, consider the tour's duration and inclusions. Some tours might offer an optional visit to the Joint Security Area (JSA), though this is often subject to availability and political conditions. It's crucial to book well in advance, as these tours are highly sought after and can sell out, especially during peak travel seasons.
Be prepared for security checks and follow your guide's instructions meticulously. The DMZ is an active military zone, and adherence to rules is paramount. Tours can sometimes be canceled or rerouted due to security alerts or political developments, so it's wise to stay informed and have a flexible itinerary.
