A day on the DMZ: Imjingak, the Third Tunnel and Dora Observatory
Pick-up outside the hotel at 07:30, back in Seoul by four. That is the shape of the standard Paju DMZ day, and it covers more ground than the name suggests. The Joint Security Area, the bit with the blue huts and the soldiers facing each other across a line of concrete, has not been open to ordinary tourists since 2023. What is left is the wider zone, which turns out to be the more interesting half anyway.
Gamaksan and the Gloster bridge
The day opens away from the border with a suspension bridge, which sounds like filler and is not.
It is a ten minute uphill walk from the car park, steady rather than punishing, through trees with old military positions dug into the slope. The bridge itself is 150 metres of deck, 1.5 metres wide, slung about 45 metres above the Ungye valley. It sways, which is the point, but it is wide and solidly cabled and I would not call it frightening. If you want a bridge that scares you, this is not it.
What the tour operators tend to skate over is the name. Paju calls it the Gloster Heroes Bridge, after the 1st Battalion, Gloucestershire Regiment, who fought here at Solma-ri in April 1951 and held up a vastly larger Chinese force for three days at the cost of most of the battalion. Standing on a wobbling footbridge and being sold a photo opportunity above the ground where the Glosters were surrounded is a strange bit of dissonance, and one worth knowing about before you cross rather than after.
At the far end there is an observation deck with a large moon sculpture for the photographs, plus views across to Beomnyunsa temple and the tower on the opposite ridge.
Imjingak and the peace park
Imjingak sits about seven kilometres short of the Military Demarcation Line, outside the controlled zone, which is why it is free to wander and full of coach parties.
The centrepiece is a steam locomotive from the Gyeongui Line, pulled out of the DMZ and conserved. The account we were given: the driver was hauling supplies north, was ordered to turn back, stopped at Jangdan station, and walked off to find help. American soldiers then destroyed the train where it stood so the North could not use it. He survived because he had walked away from it, and it was his memory that located the wreck decades later. The metal is peppered with bullet damage. The track it sits on ran north, and if the line ever reopens, the South is connected by rail to China, Russia and eventually Europe. Our guide talked about that as a live hope rather than a museum caption, which was the moment the day stopped being abstract.
Alongside it, barbed wire hung with thousands of ribbons written by separated families. Our guide, AJ, said she avoids reading them because they make her cry. She quoted a few from memory anyway. Nearby is the Mangbaedan altar, where displaced people perform ancestral rites facing north towards home villages they cannot visit, and the replica Freedom Bridge, built for the 1953 prisoner exchange. The numbers there are their own small horror. The South asked for 88,000 men and got back roughly 12,000. Some of the rest were still alive to escape and testify in the 2010s, in their seventies and eighties, describing years of mine clearance and mine work as forced labour.
A short walk on is the Peace Bell, a bronze bell hung inside a red-columned pavilion and rung by visitors on days of significance, each toll intended as a wish for reunification.
Near the old railway line stands a Statue of Peace, one of the seated girl figures found at memorial sites across the country, commemorating Korean women and girls forced into sexual slavery by the Japanese military — a reminder that the peninsula's twentieth century holds more than one unresolved history.
The barbed-wire perimeter runs the length of the park, fencing off the river approach even here, well short of the checkpoint proper.
The defector talk
The site runs a film and a live talk by a defector, with English translation.
The line that stayed with me was about schooling: children are taught, and repeat, that North Korea is the best country in the world. Sitting there, I found myself wondering how many Americans hear that and think about the pledge their own children recite every morning. The talk also included a straightforward admission, that she had been taught the South was effectively an American colony and had since learned it was not true. You then walk out into a souvenir shop where half the merchandise is printed with the Stars and Stripes. Nobody involved seems to notice.
The film footage of rural North Korea was presented as shocking. It showed shacks, dirt roads and old rolling stock. I have seen the same in rural Cambodia and across large parts of Africa, and I have ridden a train in Egypt built in West Germany. Poverty is not proof of anything on its own, and the footage is doing less work than the framing suggests.
One incident I have not decided how to read. As two tourists tried to join the defector talk, a member of staff stepped in front of them, shouted "no Chinese," and turned them away. She did work there, so it was not a bystander. It may have been a blanket policy, or it may have been an aggressive way of saying the session was the English one. I could construct a case for a genuine ban, given that China is the reason the North still exists, but I would be guessing. What I can report is that it happened, loudly, in front of a room of visitors.
Into the Civilian Control Zone
After Imjingak the bus is checked by a soldier who boards, masked, and works down the aisle with the passenger list. Bring your passport. It is a short piece of theatre with real consequences behind it, and it does set the tone. The message as we approached was if anyone's forgotten their passport or got the details wrong no one is going in.
You cross on the Unification Bridge, opened in 1998 and built by Hyundai. Chung Ju-yung, the founder, was born in what is now North Korea and funded his escape south with money from a cow sold off his father's farm. In 1998 he drove convoys of cattle back across, 1,001 head in total, framed as repayment. Everyone calls it the cow bridge.
Some geography, because it clears up a common muddle. The DMZ is two kilometres either side of the Military Demarcation Line, so four kilometres wide, running 248 kilometres across the peninsula. South of that sits a Civilian Control Zone, roughly eight kilometres deep on this stretch, which is where the tour actually spends its time. There are working rice fields inside it and people farming them. The road you are on is National Route 1, which runs south to Mokpo and, on paper, north through Panmunjom to Kaesong, Pyongyang and Sinuiju. It stops at the border. Traffic beyond the checkpoint is mostly military.
Dora Observatory
A steep climb up to the observatory, and no photographs inside. None at all. I will sometimes bend, break or laugh at a rule I think is pointless, but I do not play games with foreign military police.
Through the glass, and through the fixed binoculars, you get Kijong-dong, the North's showpiece village, where the buildings have doors and windows painted on and nobody lives. Above it, a hillside slogan in Korean characters laid out like the Hollywood sign, which our guide translated as our country is the best. I picked out a soldier on a guard post. No cars, a few bicycles.
On the southern side is Daeseong-dong, which is a real village of about 140 people inside the DMZ itself. Residents pay no tax and do no military service. A man can bring a wife in from outside, but a woman who marries out has to leave, since bringing in a husband would hand a man an exemption from conscription. There is an elementary school and nothing beyond it, so the population drifts away and the village keeps shrinking.
Practical note: the binoculars are set at fixed heights. Do not end up at the children's ones.
The Third Infiltration Tunnel
Discovered in 1978 after a defecting engineer described the programme and the South drilled more than a hundred water-filled pipes across the suspected line until one of them blew. The North's defence was that it was a coal mine, so they smeared the walls with coal dust. The rock is granite. Four tunnels have been found; the guides will tell you the working assumption is that there are many more.
I did not go down, and I would make the same call again. I have no fear of heights, or strange places. I've scaled mountains and dove the depths but I will not climb into a tunnel by choice. It is a 300 metre access ramp to reach the tunnel, roughly 75 metres below ground, the tunnel drops to about 1.5 metres of headroom, the air is thin and stale, it is crowded, and cameras are banned. The monorail that saves you the climb back up was out of service. If I could have photographed even the descent I might have talked myself into it. My guide worked hard on me. I stayed put and looked at the small museum instead, which is oddly hard to find, and the souvenir shop, which is not.
If you are reasonably fit and do not mind enclosed spaces, go down. It is the single most concrete thing on the tour. Just be honest with yourself about the climb back out.
Unification Village
Last stop, and slight. A small farmers' market inside the control zone, growing rice, soy and ginseng, worked by families who moved in from the 1970s when the government leased the land cheaply to retired soldiers and displaced people, on the understanding that they would farm the frontier and help watch it. Around 430 people live there now. There are a couple of other options here, including a JSA replica museum we skipped, but mostly it is lunch, a toilet stop and one more rack of souvenirs before the hour back to Seoul.
The JSA question
You will see JSA tours advertised. Treat that with caution.
Public access was suspended in July 2023 after a US soldier, Travis King, broke away from a tour group and ran across the line. He was held for a little over two months and expelled. How bad a person must you be to be a prime propaganda tool like a US soldier who defected, to be expelled after only 10 weeks? Tours briefly reopened in limited form in 2025 and were pulled again later that year. As of early 2026 there is no reliable public schedule, and no operator can guarantee access on the day. Book the DMZ tour for the DMZ. Do not pay a premium for a JSA that may not happen.
Verdict
Worth the day, and not for the reasons the marketing suggests. The best of it is the ordinary detail: rice fields under a checkpoint, ribbons on wire, a train left where it was shot, a road that goes nowhere and was built to go to Sinuiju. The weakest of it is the parts that try hardest, the propaganda poverty footage and the gift shops. Go, listen carefully, and do your own arithmetic on what you are shown.
