Thien Duong was discovered in 2005 by a local resident and then explored by the British Cave Research Association (BCRA). Initially, explorers covered a modest 5km of the cave, but their subsequent explorations discovered the cave is 31km long, surpassing the previously recognized longest cave in the national park, Phong Nha Cave.

Towering up to 72 meters with an impressive width of 150 meters, Thien Duong Cave’s magnificent limestone formations, stalactites, and stalagmites led explorers to name the cave Thien Duong as it is truly a paradise on Earth.

Recognized as a UNESCO World Heritage Site, the cave has been meticulously developed for exploration while ensuring the preservation of its pristine beauty.

Thien Duong Cave has blossomed into a sought-after destination for tourists in Vietnam.
