About Thien Duong Cave
Thien Duong Cave (Paradise Cave, Hang Thiên Đường) is a large limestone cave in Phong Nha-Kẻ Bàng National Park in central Vietnam, discovered and surveyed in the mid-2000s. It is one of the park’s largest and most-visited showcaves with long internal galleries and extensive speleothem formations.
The cave was located by a British-led expedition in 2005 and subsequently surveyed and measured; infrastructure to allow public visits was installed and opened in the following years. Since opening, it has become a standard stop for visitors to the Phong Nha region.
Thien Duong sits within Phong Nha-Kẻ Bàng National Park in central Vietnam, on the karst plateau west of the coastal city of Đồng Hới and reached by road from nearby park entrances.
