Thien Duong (Heaven) Cave, located in the World Natural Heritage of Phong Nha-Ke Bang National Park, is an attractive destination thanks to its magical and mysterious formations.
The 31-kilometre cave, situated in the middle of a limestone mountain range, is the longest dry cave in Asia.Its width ranges from 30 to 150 metres, with an average height of around 60 metres. Tourists have recently been allowed to visit seven kilometres of the cave that have previously been off limits.
Unlike Phong Nha cave or Tien Son cave, which also belong to the Phong Nha-Ke Bang complex, the atmosphere in Thien Duong remains relatively cool and moist, with an average temperature of from 20-21 degrees. The cool air can be felt sitting in front of the cave’s opening.According to many, the stalagmites in Thien Duong cave are more spectacular than those found in Phong Nha Cave. Many people claimed to have seen images of tigers, elephants, fish and even gods in the formations within the cave.
