Paradise cave is the longest dry cave in Asia located in Phong Nha – Ke bang National Park’s core zone. With naturally primitive features, Paradise Cave looks like a landscape painting; making it a natural wonder that many have enjoyed since its opening in 2010. The cave height can reach to 72m and up to 150m wide. There are a series of white crystal stalactites (limestone deposits) resembling natural pillars and many other spectacular formations. Visiting this cave includes a buggy ride through the jungle, a 200m sloped hike up to the mouth of the cave and a 1km exploration down into the cave along wooden boardwalks installed to protect the ancient stalagmites and stalactites. All of the magnificient formations are delicately lit up to highlight its grandeur.

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.
