Phong Nha cave or the “river cave” is situated along the historic Ho Chi Minh trail and stands as a relic system of the American/Vietnam war. This cave was actively used to aid the route supporting the battleground of South Vietnam. Safe from the routine bombings, it was used as a place to hide secret floating bridges
that would be brought out at night and placed over the river to help trucks get supplies to the south. It once served as a hospital, with weapons installed at the entrance. Today, this area has become the first section of the ever popular Ho Chi Minh Road, as it showcases as lush, mountainous landscape. Visiting this cave includes a 6km dragon boat ride up the turquoise Son river and into the cave where you can marvel at the cave’s magnificient structure. Drift 1km
into the cave before exploring 300m on foot.

The Dark cave is an adventurous and action- packed experience. Visiting this cave includes harnessed zip lining over a turquoise river, swimming into the mouth of the cave (lifejackets included), walking through the dark with only the head torch on your mining helmet to illuminate the way, floating about in the buoyant mud baths deep in the cave, washing clean with a swim in the lake inside the cave, then kayaking back across the river to test your strength
on the hanging obstacle course and open ziplines. The Dark cave is named as such because it is one of the few caves that has had no artificial lighting installed. The cave is comprised of mostly basalt, in addition to limestone. Basalt is a black, hard rock; also contributing to the cave’s name.
