After the discovery in 1990, Dark cave was soon put into operation as a tourist attraction in Phong Nha. The cave is famous for lots of adventurous activities such as Zipline, kayaking, and cave discovery.

Where is Dark Cave – Chay River?
Dark Cave is located on Ho Chi Minh West road, in Bo Trach, Quang Binh, Vietnam.
The location of the Dark cave is about 60 km from Dong Hoi, and it takes more than 1 hour to drive from Dong Hoi to Dark Cave.
If you stay in Phong Nha town, the distance is approximately 20 km, and it takes 30 minutes to get there.
Do you know that Dark cave – Chay River is located only 2km away from the ecotourism site Thien Duong Cave and 500m from Mooc River?
I would suggest combining either Thien Duong Cave or Mooc River in one day along with your visit to the Dark cave as the location of these attractions is quite far away.
How to get to Dark Cave – Chay River
a) By motorbike
If you’re an adventurous traveler, you can rent a motorbike for one day in either Dong Hoi or Phong Nha. I rent my bike from MotorVina and love the service.
On the way to Dark Cave, you will be amazed by the scenery with beautiful rice paddy fields, local houses, and small paths.
Note: If you don’t have experience in driving, you should better hire a motorbike driver.
b) By car
If you’re traveling by group, it can be an excellent choice to rent a charter car for a day or more.
c) By Tour
Several companies are offering daily tours from Phong Nha/ Dong Hoi to Dark Cave. The most common one is a day tour to Dark Cave and Thien Duong Cave.
Although the ideal time to visit Phong Nha-Ke Bang attractions is from March to September, the best time to visit Dark Cave is from the middle of March to May.
At this time, the scenery is gorgeous with blue sky, white clouds, and turquoise water. Also, the weather is cold and not too hot, so it’s easy to enjoy outdoor activities.
It can be crowded from June to August as it’s the high season for local tourists to visit this site.
From September until March next year, the weather is cold with storms, so I would not recommend traveling here.

Before the fun starts
When you get to the location, the instructor will give you general information about the Dark Cave.
They will show a video of activities that visitors can do there and introduce the activity packages. As I mentioned above, there are two packages that you can choose from.
After deciding on the package, you will need to sign a form and take it with you when purchasing the ticket. The form indicates your health and mental standards to participate in this experience. Also, there’s a part of insurance and safety protocols.
If you need to rent a locker, it’s compulsory to pay a 50000 VND deposit for a lock. The money will be returned after you return your lock, so keep your key tight!
What to wear in Dark Cave
To participate in the Discovery program, women are required to wear a bikini or basic swimsuit, while men wear swimsuit pants.
Therefore, it is necessary to prepare them in advance or buy them at Dark Cave.
After changing to an appropriate swimsuit, you will then guided by the staff to put on a safety belt, life jacket, hat, and headlamp to ensure the safety requirements.
Things to do in Dark Cave Chay River
Try the longest Zipline in Vietnam
The zip line is my favorite part of Dark Cave. I was super scared at first and hesitated to try it due to my fear of height.
The swing was not too fast, and I could enjoy the scenery around. As the zip line was just 400 meters, it was quick to get to the other part.
Tips: You can carry your GoPro or selfie stick, but be careful not to drop it.
Explore Dark Cave
After the zip line, we swam a short distance to the entrance of the Dark Cave. Our guide gave a brief instruction of Dark Cave, and we followed him into the cave.
The cave was completely dark and brought a strange and exciting feeling. The flashlight mounted on each helmet was the only means to light up the way, so we had to stay close together and not get lost.
As the path to the Dark Cave was narrow and slippery, we had to wriggle through small slots and not fall. After walking about 100 meters to the cave, I could feel the mud under my feet and touch them on the surrounding.
It was amazing to explore the cave even though it was just a short trip.
Enjoy mud bath
We found a natural mud bath after walking 500m into the cave and relaxed there for about 10 to 15 minutes.
This mud bath was formed thanks to the high level of water in the rainy season. The mud bath has essential minerals that are suitable for skin and relaxing purposes.
After relaxing at the mud bath, we walked to a small lake to wash the mud layer and enjoy the feeling of fresh skin after the natural Spa course.
Kayaking on Chay River
We then walked back to the entrance and got on the kayak to the activity spot. Doing the kayak racing between our group was fun.
About Chay River
From February to August, the weather is sunny, and the Chay river has crystal clear water.
However, from September to October, it starts to rain a lot, and Chay water becomes muddy caused by the soil that flows into the river.
From December to January, the water is cold and difficult to swim.
Participate in outdoor activities on Chay River
From March to August is the best time to enjoy outdoor activities on the Chay River.
There are a few games that you can do there, and I love the zip line one. Sliding the zip line to the middle of the river and dropping from above to the cold water creates an extreme feeling.
Tip: There’s a kid swimming pool on Chay river as well, so it’s a great bonus if you’re traveling with kids.
Where to stay in Phong Nha
I would suggest staying in Phong Nhainstead of Dong Hoi to save your travel time between the attractions. Also, Phong Nha town is charming, and the surrounding nature is stunning.
