Thien Duong (Paradise) Cave is a newly found cave in this area. Prior to the discovery of Son Doong Cave, it was regarded as the largest and longest cave in Phong Nha-Ke Bang. Some of the most beautiful and spectacular stalactites and stalagmites in the park are found within Thien Duong. It was opened up to tourists in early 2011 with a 1.1 km path to see the beautiful formations. A comprehensive survey has not yet been conducted due to the inherent dangers; therefore, knowledge of this cave is limited and it remains a mystery to the scientists.
