Seoul DMZ Tour: Third Tunnel, Dora Observatory & Red Bridge

Summary

Walk tunnels under the DMZ, peer into North Korea and cross a swaying bridge

You’ll step inside history on this DMZ day trip from Seoul — walking through Imjingak Park’s quiet memorials, exploring the eerie Third Tunnel beneath the border, peering across into North Korea from Dora Observatory, and (if you want) crossing the swaying Red Suspension Bridge over Seolmari Valley. It’s a day that lingers long after you’re back in Seoul.

What’s the experience like?

I almost missed the pickup because I’d convinced myself I needed one more coffee — classic me. The driver waited, smiling like he’d seen this before, and we joined a few others heading north out of Seoul. Our guide, Minji, started chatting about her own family’s stories from the war, which felt surprisingly personal for a group tour. I caught a whiff of pine as we neared Imjingak Park; someone nearby was eating kimbap and honestly it made me hungry even though it was barely 9am. There’s an old train there — rusted but proud — just sitting on broken tracks that used to run all the way through to Pyongyang. It’s hard not to stare at it.

The DMZ tour really hit me in the Third Tunnel. You put on these hard hats (mine kept slipping) and duck your way underground where North Korean soldiers once tried sneaking through. It’s damp down there, with echoes bouncing off rough stone walls — you can hear people’s footsteps behind you but can’t always see them. Minji pointed out drill marks and explained how they found coal dust smeared everywhere as cover-up; I didn’t expect to feel so uneasy in such a small space. When we came back up, sunlight felt weirdly sharp, almost too bright after that tunnel.

Dora Observatory is where you get to look right into North Korea through those big binoculars. It was hazy but I still saw that “propaganda village” everyone talks about — empty buildings painted cheerful colors but no one moving around. A couple next to us argued over whether they could spot Kaesong City or not (they couldn’t agree). The air smelled faintly metallic up there, maybe from all the fences and barbed wire? I don’t know. We skipped strawberry picking but did try the Gamaksan Red Suspension Bridge at the end — it wobbles just enough to make you laugh nervously if you’re not great with heights (I’m not). The view down into Seolmari Valley is something I still think about when things get too noisy back home.
