The Dark Cave was first discovered back in 1990. Soon after its discovery and exploration, the locals realized that it could be opened up for commercial use and bring worldwide travellers closer to Phong Nha – Ke Bang National Park in terms of the soft-adventure and natural thrill it can offer. Since the Dark Cave tours in Phong Nha started being operated, it has played a great role in terms of giving travellers a wonderful experience if they’re looking to spend a day out in the wild, filled with adrenaline and fun with friends.

Back in 2014, a decision was made to build a 400 meters long double zip-line which will serve as the apparatus to the entrance of the cave. This zip-line is known to be the longest zip-line in all of Vietnam and has also led to achieving a Vietnamese Guinness Record award at the Quang Binh province cave festival of 2015. All the early travellers that used this giant zip-line to access the the Dark Cave’s entrance called it one of the most adventurous and memorable experiences of their life, as zip-lining down above a river to an entrance of a cave isn’t something you get to do everywhere.

You’ll get to experience the geological beauty of the Dark Cave with your whole body, as you make your way deeper inside the cave. The Dark Cave in Phong Nha – Ke Bang National Park is measured to be approximately 6 KM long. On your Dark Cave tour in Phong Nha, you’ll notice that the cave is primarily formed of crevasses that get narrower as you move deeper, muddy bottoms, thick clay walls.

The mud that you find inside is actually quite remarkable!

The pattern, color and consistency of the mud inside the cave make it seem akin to pure chocolate milk. Another amazing part about the mud inside the Dark Cave is that it’s completely buoyant; you will not sink at any point during your adventure inside the darkness of the cave! The nature of the mud makes you float around rather nonchalantly and the mud-pits are considered to be one of the geological highlights of the Dark Cave.

The Dark Cave is considered to be an adventure playground for travellers also due to the features of the cave and how you get to be a part of it in true essence. For instance, if you’ve joined a Paradise Cave tour, you’ll notice that you get to walk to boardwalks and calmly admire the beauty of the cave’s formations with the artificial lighting system involved. However, the Dark Cave tours are quite the contrary. Here, it’s all about jumping in and being part of the adventure from the get go!

After you zip-line to the entrance of the cave Indiana Jones style, it’s time to put on your caving helmet (this will be provided to you by the management there). You’ll find a headlamp attached to your helmet and guided by its light, you’ll make your way barefoot through a crevasse that you’ll notice getting narrower as you continue. This steadily narrowing crevasse also gets muddier with each passing moment and eventually leads you to a section where you’ll be surrounded by thick clay walls on both sides and even underfoot.

As you keep moving forward, you’ll be welcomed by no trail at all and only deep and muddy footprints of the adventurer walking ahead of you. The whole little journey of 300 meters filled with squelching will surely be a really entertaining, funny and memorable experience for you. Please bear in mind that if you suffer from claustrophobia, Dark Cave will surely push you to the limits!

After making your way further, you’ll find that the crevasse you were clumsily traversing leads you to a giant mud pit. Once you get through all this, you’ll be invited by the cave’s cold river where you can enjoy swimming and de-mudding while reinvigorating yourself (in pitch darkness). You will make your way back by kayaking and to accentuate your overall experience, you also get to enjoy a special obstacle course over the water and even a flying fox! For many travellers, dipping in the jade blue Chay River on hot summer days is perhaps the most special part of this entire experience!

After getting done with your adventure, you can grab some grub at the Dark Cave restaurant where you can enjoy the traditional Vietnamese delicacies that’ll surely be an appetizing end to your adrenaline-filled day.

Please note that limited number of visitor can go in the cave for mud bath at a time, be prepared!
