Động Ngườm Ngao cave is a beautiful and surprisingly large cave near Ban Gioc waterfalls. It is not that well know, and located at the end of a little dirt road off TL206. Even though it is not on everybody’s radar, I would highly recommend adding a visit to this cave when heading to Ban Gioc.
How to get there
From Cao Bang it is around 90km to Ban Gioc, where the cave is located nearby. I saw a few buses going that way, but you might need to change buses in Quang Nguyen first. Check at the bus station if direct buses are going. Some might stop at the village nearby, which is 20 minutes away from the cave falls. An alternative way is hiring a private car, or even better, try hiring a motorbike. The road from Cao Bang all the way to Ban Gioc and the cave is in good condition. Just follow QL3 until you reach Quang Ngai. Then just follow TL206. Following that route you will see some beautiful scenery, so having the chance to stop once in a while would make the trip more enjoyable.
