Hidden within Phong Nha-Ke Bang National Park, Quang Binh, Dark Cave is like a rough gem, captivating visitors with its pristine beauty, mystery, and challenging adventures for those who love to explore.

 Discovered by BCRA (the British Cave Research Association) in 1992, Dark Cave has an impressive name due to the darkness that envelops it year-round as there are no openings for light to enter. With a length of 5,258-meters, the cave system is like a secret world hidden with countless wonders.

The special feature of Dark Cave is the Exit (back entrance), where you begin your exploration journey. Located in the Abandoned Valley, the Exit possesses a majestic and mysterious beauty with a 50-meters high and over 20-meters wide ceiling. Stepping through this Exit door, you feel like you’ve entered a completely different world. The exploration is enveloped in a completely silent darkness. 

To navigate Dark Cave Exit, you need specialized lighting equipment to explore the layers of marlstone and siliceous limestone cliffs. Be cautious when crawling through sharp rock cliffs and crossing mud ponds ranging from 200 to 500 meters long. The cave has a complex geological structure.

The geomorphology of the Dark cave belongs to the ancient strata in the Abandoned Valley area. Dark cave plays an important role in the process of researching the history and determining the age of the entire cave systems in Phong Nha-Ke Bang. Therefore, conquering Dark cave is one of the most exciting and challenging journeys in Abandoned Valley. You need to prepare a healthy body, adaptability, and a brave spirit.

Pristine beauty, a challenge for adventurers
