The Heart of Phong Nha – Ke Bang National Park.
Located in Phong Nha–Ke Bang National Park in Quang Tri Province, Central Vietnam, Phong Nha Cave is one of the most famous and accessible caves in Vietnam.
The name “Phong Nha” means “Wind and Teeth”, referring to the cave’s sharp stalactites that resemble giant teeth. With its spectacular underground river, stunning limestone formations, and rich history, Phong Nha Cave has been recognized by UNESCO as part of the world’s natural heritage.
Often called the “First Wonder of Caves” in Vietnam, this site is a must-visit for nature lovers and adventure travelers.
A Brief Overview of Phong Nha Cave
- Location: Phong Nha – Ke Bang National Park, Son Trach Commune, Bo Trach District, Quang Binh
- Length: Over 7,700 meters, with about 1,500 meters open to tourists
- Highlights: Underground river, rock formations, and historical wartime shelters
A Natural Masterpiece
Phong Nha Cave is famous for its underground river, one of the longest in the world. Visitors explore the cave by boat, gliding along calm blue waters beneath cathedral-like ceilings of limestone.
Inside, you’ll find:
- Magnificent stalactites and stalagmites shaped like lions, Buddhas, and fairies
- Wide chambers with sparkling mineral walls
- Cool, fresh air year-round — around 20–22°C
History and Significance
Phong Nha Cave has been known to local people for centuries, but it became internationally recognized after the British Cave Research Association (BCRA) surveyed it in 1990 and 1992.
During the Vietnam War, the cave was also used as a hiding and storage area for weapons due to its remote location and natural protection.
Today, it’s not only a geological wonder but also a symbol of Vietnam’s resilience and natural beauty.
How to Visit Phong Nha Cave
Phong Nha Cave is one of the easiest caves to visit in the park, suitable for all travelers — from families to solo adventurers.
Here’s how you can plan your trip:
Step 1: Get to Phong Nha Village
Phong Nha village is about:

- 220 km from Hue
You can reach Phong Nha by:

Once in Phong Nha village, most guesthouses and homestays can help you book a cave tour easily.
Step 2: Go to the Phong Nha Tourism Center
The main ticket office and boat pier are located in Phong Nha town, by the Son River.

Along the way, you’ll pass peaceful countryside views, floating houses, and children swimming in the river — a glimpse into rural life in Quang Binh.
When your boat glides into the dark mouth of the cave, the temperature drops and you’ll feel a sense of mystery and awe.
