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.
- Public access length: A developed visitor route of about 1 kilometre provides easy access to the main chamber and the most impressive formations; additional sections are accessible only with guides and permits.
What to See #
- Show-cave walkway: The main show-cave walkway installed when the cave was opened to visitors, allowing access along roughly 1 kilometre of the best-preserved chamber and formations.
- Wild passages: Wilder passages beyond the public route that extend further into the system and are visited only by caving teams or with special permission.
How to Get to Thien Duong Cave #
Thien Duong (Paradise) Cave is inside Phong Nha-Ke Bang National Park near the village of Phong Nha. From Dong Hoi (airport and railway) travel northwest to Phong Nha village, then continue by tourist shuttle, taxi or rented motorbike to the cave area - the drive from Phong Nha village to the Paradise Cave parking/visitor area is a short regional road transfer (commonly arranged by tour operators and hotels in Phong Nha).
Visitor facilities include a car park and a short walk from the parking area to the cave entrance; regular day‑trip shuttles and guided tours run from Phong Nha village.
Tips for Visiting Thien Duong Cave #
- Paradise (Thien Duong) Cave is easiest to visit during the park's dry season to avoid road and trail closures; check local shuttle timetables from Phong Nha village before you travel.
- Access the cave from the Phong Nha park entrance-there is a short walk from the parking/shuttle drop to the cave mouth and paid access is managed at the site, so arrive early to secure a morning slot.
- Many visitors only see the well-lit main walkway; consider a guided program or combine with nearby Dark Cave activities to experience the surrounding karst landscape and quieter trails.
