If you drive about two hours east of Bangkok, heading toward the Cambodian border, the landscape starts to flatten out into a haze of rice paddies and dust. Most travelers skip this part of Sa Kaeo province. They’re usually rushing toward the neon chaos of Poipet’s casinos or the ancient stone faces of Angkor Wat. But there is a patch of land here, tucked near the foot of a small hill, that was once the most densely populated place on earth.
Khao I Dang Thailand isn't a name you'll find in many glossy travel brochures. Honestly, it’s a bit of a ghost.
Back in 1979, this wasn't a forest conservation area or a quiet learning center. It was a city. A city of bamboo, blue plastic tarps, and absolute desperation. After the Khmer Rouge fell, hundreds of thousands of Cambodians stumbled across the border, literally starving and covered in the dust of the "Killing Fields." Khao I Dang was where they landed.

The "Bamboo City" That Saved a Generation
When people talk about Khao I Dang Thailand, they often call it the "Holding Center." That sounds clinical, almost like a warehouse. But for the 160,000 people crammed into just over two square kilometers at its peak, it was the only thing standing between them and a shallow grave.
The camp opened in November 1979. Within just a few months, it became the eleventh-largest "city" in Thailand. It was a massive logistical nightmare. Think about it: you have to truck in every single drop of water. 10 to 15 liters per person, every day. If the trucks didn't show up, people didn't drink.
It was a strange, temporary civilization. There were hospitals run by the International Committee of the Red Cross (ICRC), schools where kids learned in the dirt, and even traditional dance troupes trying to keep Khmer culture alive while their country back home was a smoking ruin. Many of the refugees were the "intellectuals" Pol Pot tried to wipe out—doctors, teachers, artists. Because they spoke French or English, Khao I Dang became the "elite" camp, the primary gateway for those hoping to resettle in America, France, or Australia.

It wasn't some peaceful sanctuary. Not even close.
While the UN and NGOs were doing their best, the camp was a pressure cooker. You had Thai soldiers on the perimeter who weren't always friendly. You had "illegals"—refugees who hadn't been officially registered—hiding in literal holes in the ground or under floorboards to avoid being pushed back across the border.
Violence was a constant. Night raids by bandits were common. One survivor, Youk Chhang, who later became a famous historian, remembers hiding in a well to escape patrols. Others tell stories of grenades being tossed into huts over petty thefts.
And then there was the "Dangrek Pushback." This is a part of the Khao I Dang Thailand story that many people get wrong or forget. Before the camp was fully established, the Thai military actually forced thousands of refugees back over the Dangrek Mountains at gunpoint into minefields. It was a massacre. Khao I Dang was, in many ways, the world’s guilty response to that horror. It was a place where "humane deterrence" finally gave way to just... humanity.
Visiting Khao I Dang Today: What to Expect
If you go there now, don't expect to see a bustling city. The bamboo is gone. The blue tarps have rotted away.

Today, the site is the Khao I Dang Learning Center. It’s managed by the Thai Forestry Department. It’s quiet. Maybe too quiet. There’s a small museum with photos and a scale model of what the camp used to look like. You can see the old surgical ward foundations if you look closely enough through the weeds.
Getting There
You basically have to want to find it. It’s about 35 kilometers north of Aranyaprathet.
- Take a bus or train from Bangkok to Aranyaprathet.
- Hire a local driver or hop on a motorbike taxi. Just say "Khao I Dang"—the locals know it.
- The "Learning Center" is usually open, but it’s a good idea to check their Facebook page or call ahead, as it’s tucked away in a forest area.
Why This Place Still Matters
We tend to look at refugee camps as "problems" to be solved. Khao I Dang was different. It was a incubator.
Nearly 235,000 Cambodians passed through this specific patch of dirt on their way to new lives. If you meet a Cambodian-American in Long Beach or a Cambodian-French family in Paris, there is a massive chance their family story has a chapter set in Khao I Dang Thailand.
It’s where surgeons who hadn't held a scalpel in years finally got back to work. It’s where children who had seen nothing but war learned their first ABCs. It was a place of "excruciating loss and relative joy," as scholars often put it.
Actionable Insights for the History-Conscious Traveler
- Don't just look at the photos. Walk the perimeter. Try to imagine 160,000 people living in a space smaller than a typical airport. The scale is what hits you.
- Support the Documentation Center. If you want to dive deeper, look up the Documentation Center of Cambodia (DC-Cam). They are the ones doing the heavy lifting to preserve these stories.
- Combine your trip. If you're visiting the Sdok Kok Thom Khmer temple (which is stunning and nearby), make Khao I Dang your second stop. It provides the modern context to the ancient history you see at the ruins.
- Talk to the guides. Some of the people working in the area have family who were either guards or workers during the camp years. Their perspective is often much more nuanced than the official plaques.
The camp finally closed in 1993. The last residents were sent back to Cambodia or off to the US. But the land doesn't forget. When you stand at the base of the hill today, you aren't just looking at a forest. You're looking at the place where a nation's soul was kept on life support.
