Vom cave system

The Vom cave system consists of Vom, Dai Cao, Duot, Ca, Ho, Over, Pygmy, Ruc Caroong grottos. In the cave system, there are a huge number of beautiful stalactites and stalagmites. Notably, the Arem minority has lived in Ruc Caroong cave as the natural hunter-gatherers.

Tien Son cave

Tien Son or Dry cave is a famous cave in the Phong Nha - Ke Bang area. The cave has several fanciful and majestic stalactites, stalagmites as those in Phong Nha cave, but there is a distinctive sound from the stones and stone columns when they are knocked in the cave, creating an echo like the sounds of gong and drumbeat.

According to the British researchers, Tien Son cave was formed tens of millions of years ago when a stream flowing through the mountain had eroded and excavated Ke Bang limestone mountains. Later, the geological formation of this mountain mass that had been raised or lowered caused the rocks to collapse, preventing the flow and creating Tien Son cave at the top. The river then flew through the underground, creating Phong Nha cave. Phong Nha and Tien Son cave are located adjacent to each other, but these caves are not connected.

Thien Duong cave

The cave was discovered in 2005 and had a total length of 31 kilometers. Due to the beauty of the cave, it was named as Thien Duong or Heaven cave. The cave is considered to be larger and longer than the Phong Nha cave. It is a dry cave without underground rivers flowing like Phong Nha. There are many stalactites and stalagmites in the cave, and the atmosphere is extremely cool and fresh. The ground here is soft and flat that is convenient for sightseeing and exploring.

Son Doong cave

Son Dong or Son Doong is one of the newest caves discovered in the Phong Nha - Ke Bang area. The cave is considered to be the largest cave in the world, 4-5 times larger than Phong Nha cave, and also Thien Duong Cave. The largest cave in Son Dong is over 5 kilometers long, 200 meters high and 150 meters wide, which is said to be able to contain the largest Boeings in the world. In the cave, the researchers found an underground river with a 2.5-kilometer length of the stalactites which are up to 70 meters high. The cave also has coral populations and fossil relics.

Also, the cave has two "skylights" where the ceiling collapsed, bringing sunlight into the cave, and enabling the ecosystem here to grow like a tropical jungle in a cave as "Adam's Garden."
