Dark Cave (Hang Tối)
Hang Tối
A zip-line into the cave, a headlamp to explore the darkness, a natural mud bath, and a kayak trip back. It is the most popular adventure activity in Phong Nha.
Dark Cave is located on the Chày River near Moc Khe. It has no lighting inside, which gives it its name. The activity goes like this: first take a zip line about 400 meters long across the river to the cave mouth, then swim into the cave. Wearing headlamps, walk to the deep natural mud pool and float in it. Afterward, return to the river to kayak and play on water rides and zip line into the water. Admission is about 450,000 VND, including equipment. You need to be able to swim (life jacket provided), bring a change of clothes, and store valuables in lockers. It is often combined with Paradise Cave in the same day.
