The 3rd Imfiltration Tunnel

The best time to visit The 3rd Imfiltration Tunnel is during spring (April to June) or autumn (September to November) when the weather is mild and comfortable. Expect clear skies and pleasant temperatures, perfect for exploring the tunnel and nearby outdoor attractions like Imjingak Pavilion and Dora Observatory. Summers can be hot and humid, while winters are cold, so dress accordingly for your visit.

Must-see attractions include descending into The 3rd Imfiltration Tunnel itself to experience its narrow corridors and military barricades. Also visit the Imjingak Pavilion, which commemorates Korean War history, the DMZ Peace Park, and the Dora Observatory for panoramic views of North Korea. These sites together provide a comprehensive understanding of the Korean conflict and the DMZ region.

Most visitors start their journey from Seoul, South Korea’s capital, which is about 52 kilometers from the tunnel site. From Seoul, you can join organized DMZ tours that include transportation or take public buses or taxis to Imjingak Park, where tours to The 3rd Imfiltration Tunnel begin. Advance booking is recommended and identification such as passports is required for entry.

A unique fact about The 3rd Imfiltration Tunnel is that North Korea built a fake factory near the border to mask construction noises during its excavation. The tunnel was discovered only after a North Korean defector revealed its existence, which was initially doubted by South Korean officials until boreholes confirmed the tunnel. It reflects the secretive and strategic military efforts during the Korean conflict.

Visitors often combine their visit to The 3rd Imfiltration Tunnel with nearby attractions such as Imjingak Pavilion, the DMZ Peace Park, Dorasan Station, and the Dora Observatory. These sites provide additional historical context and scenic views of the DMZ and North Korea, making for a rich half-day or full-day itinerary exploring the border region.
