It is considered one of the largest and most beautiful dry caves in the world, with ceilings reaching heights of up to 72 meters.
The cave is formed within a karst mountain massif estimated to be between 350 and 400 million years old.
Unlike many other caves in the region that contain active river systems, Paradise Cave is a fossil cave, meaning its underground river has long since dried up.
The temperature inside the cave remains a constant 20-21 degrees Celsius throughout the year.
A specialized 7-kilometer trekking tour is available for advanced visitors that goes much deeper than the standard public walkway.
Paradise Cave, known locally as Thiên Đường Cave, is a massive dry cave system located within the Phong Nha-Ke Bang National Park in Quảng Bình Province. Discovered in 2005 by a local resident and explored by the British Cave Research Association, it is recognized for its immense scale, stretching 31 kilometers in length. The main public-access section features a wooden walkway spanning the first kilometer to protect the delicate limestone formations. It is characterized by high, cathedral-like ceilings and an extensive collection of stalactites and stalagmites. The cave maintains a constant internal temperature significantly cooler than the external tropical climate. Visitors access the cave entrance via a climb or a shuttle service from the base of the karst mountain.
The first 500 meters of the walkway, where dramatic floodlighting highlights the largest and most complex limestone formations.
Wear sturdy, non-slip footwear as the wooden walkways can become slick due to high humidity.
Bring a light sweater, as the internal temperature is notably cooler than the jungle outside.
Rent the electric shuttle from the parking area to the base of the mountain to save energy for the final ascent.
Avoid visiting during the peak of the rainy season (September to November) as flooding can occasionally restrict access to the park or interior paths.
Do not touch the stalactites or stalagmites to prevent damage from skin oils; stay strictly on the wooden walkway.
