Paradise Cave (Hang Thien Duong) discovered by scientists of the British Caving Research Association in 2005, has a length of 31km, the longest dry cave in Asia. With naturally primitive features, Paradise Cave looks like a landscape painting, making it very attractive to visitors. According to spelunkers, the deeper one journeys into the cave, the more one feels the wells of heavenly clarity all around. There are a series of white crystal stalactites resembling glass pillars and many other spectacular formations.
