Pac Bo Historical Site: Ho Chi Minh’s Cave in Cao Bang

To understand why Vietnamese visitors arrive here almost in a hush, you need a little background. You do not need a history degree, just the shape of the story.

In 1911 a young man named Nguyen Tat Thanh left Vietnam by ship from Saigon. He spent the next thirty years abroad, in Europe, the Soviet Union, China and elsewhere, working, studying, and slowly becoming the political figure the world would later know as Ho Chi Minh. He did not set foot on Vietnamese soil again until early 1941.

The place he chose to come back to was Pac Bo. On 28 January 1941, which fell on the second day of the Lunar New Year, he crossed the border from China at a stone marker known as milestone 108 and walked into Cao Bang with a small group of comrades. He was fifty one years old and had been gone for three decades. He picked this remote corner on purpose. It was far from the eyes of the French colonial authorities, close enough to the border for a quick exit, and the local Tay and Nung communities were sympathetic to the cause.

For the first ten days or so he stayed in the home of a local family. Then, around 8 February, he moved into a small limestone cave that the Nung people called Coc Bo, which means something close to “headwaters” or “the source of the water.” He even marked the date on the cave wall. He lived and worked out of that damp little space, and it became the headquarters for everything that followed.

Two details from those years tend to stick with people. First, he renamed the landscape around him after his political heroes: the stream beside the cave became Lenin Stream, and the mountain above it became Karl Marx Mountain. Second, it was here, at a jungle hut called Khuoi Nam a short walk from the cave, that the Eighth Plenum of the Indochinese Communist Party was held in May 1941. That meeting created the Viet Minh, the independence movement that would go on to lead the resistance and, eventually, the August Revolution of 1945.

There is one more marker that surprises visitors. Pac Bo is also the symbolic starting point, Kilometer Zero, of the Ho Chi Minh Trail, the supply route that ran more than three thousand kilometers south toward Ca Mau. You can stand at the monument that marks it.

Here is the same story as a quick timeline:

• 28 January 1941: Ho Chi Minh crosses the border at milestone 108 and reaches Pac Bo after thirty years abroad.
• Early February 1941: He moves from a local family’s home into Coc Bo Cave.
• May 1941: The Eighth Plenum meets at Khuoi Nam hut nearby and founds the Viet Minh.
• 1941 to 1945: Pac Bo and the wider Cao Bang area serve as a revolutionary base.
• Today: The whole area is protected as a Special National Historical Site.

That is the weight the place carries. Now for the part that makes it a genuinely lovely half day even if revolutionary history is not your thing.
