Jiu Dong Tian Caves, Arch in China

 

On our visit to China, we toured the Jiu Dong Tian Cave system by boat. We had to take a tour bus down the river, hike down the river to a bridge, cross over, then take another tour bus down the other side of the river, then hike down into a cave before boarding boats to continue on through the caves. We went under this huge arch as part of the hike down to the dock. For size comparison, you can see a picnic table with a red umbrella and people standing under it. After emerging from the cave, there was another dock where others could go on the tour by going upstream. Normally, we would've continued farther down river and taken another tour bus back, but recent storms caused damage downstream, so we ended up going back through the cave a second time by traveling upstream to the original dock.

Dachuandong Arch, near Si Lian, China, 4th largest arch in the world

 

In Guizhou Province, near the village of Si Lian, is a series of sinkholes and arches. There are actually 4 arches, but we only saw the second and third ones as they are the largest. When we visited this area, a local tourism official insisted on showing us the way and accompanying us with a couple of staff members. The reason for his action is that he wanted to show the government that people are visiting these features, and there should be investments in infrastructure to accommodate more visitors. His staff members recorded him speaking about the need for investments and pointing to our group of American tourists traveling all the way here to see how special this area is. It was also good that he guided us, because we encountered very narrow roads. He posted the videos on social media, and our guide was recognized when we checked into our hotel later that same day. The video had gone viral.

The third arch was the largest. Its span of 300 feet (91.4 meters) makes it the 4th largest arch in the world. We had to hike through the second arch to get to it. The name means "big cave with a window". The Chinese, instead of using the term "natural arch" or "natural bridge," seem to prefer using their words for "heaven's gate" or "cave with window" to describe these geologic features. We were told that this particular area was used in the past for making gunpowder. Maybe it was considered a dangerous undertaking, so those engaged in the manufacture of gunpowder had to keep well away from everyone else.

Qingxudong Arch, near Dafang, China, 7th largest in the world

 

Qingxudong Arch has been measured by laser rangefinder to have a span of 251 feet (76.5 meters) and a height of 246 feet (75 meters). That happened in 2015 by Natural Arch and Bridge Society member Gunter Welz. We used our own laser ruler when we visited on May 19, 2026, and basically confirmed those numbers. This arch had plenty of visitors and cars, vans, and even a small motorhome parked underneath. It's located near the village of Yang Chang Ba in Guizhou Province, China. In terms of span, the Qing Xu Dong Arch is considered the 7th-largest arch in the world. There's a small stream flowing under it. Beyond the arch, the stream curves into a cave and ends up going underground. It's very spectacular. The Chinese word dong translates to "cave" Instead of calling these features "natural arch", the Chinese tend to use either "heaven's gate" or "cave with window."

Yunmentun Natural Bridge in China, 16th Largest in the World

 

We went on a trip to China to view 9 of the world's largest natural arches and natural bridges starting May 17, 2026. This was the first one we saw on this trip, it is number 16 on the list. Instead of calling these features "arches", the Chinese seem to prefer using the term "gate", as that is the translation for the "men" part of the name Yunmentun. Altogether it translates as Cloud Gate Village. It's been measured at 213 feet (65 meters) for its span. We rode in a boat upstream on the Yongshui River, viewed the bridge from the river side, then went under the bridge to a dock along this tributary.
