Opened to the public in 2010, Thien Duong or Paradise Cave is 31 kilometres in length, making it the longest dry cave in Asia. The interior feels as lofty, heavenly and humbling as a grand cathedral. With vaulted ceilings rich in stalactites, it’s an exceptionally pretty cave. Travelers shouldn’t miss it.
Dark cave is amazing and the true experience, kayaking over the river to get there, walking through the dark with only the head touch on your mining helmet, having a mud fight in the mud baths deep in the cave and then washing clean with a swim in the lake inside the cave.
