General characteristics of Phong Nha cave
Phong Nha cave is the most typical beauty spot of the population of caves in Phong Nha-Ke Bang and considered one of the best places to visit in Vietnam. Phong Nha was voted as one of the most beautiful caves in the world according to the following criteria: the longest underground river; the most beautiful underground lake; the highest and widest entrance; sandy beaches, the most stunning coral reefs; largest and the driest and widest caves; the most magnificent and magic stalactites and the longest water cave.
From Dong Hoi, the capital city of Quang Binh province, following Highway 1A to move to the crossroad of Hoan Lao, you can start the journey in Phong Nha cave. At Phong Nha reception center, you will take a motorboat to travel along Son river and go into Phong Nha cave. Son river is from 35 to 40 meters wide with pure blue water and you can watch fish swimming in the river. This river is called “Son” (Red) because in rainy season, rainwater that causes soil erosion falls down the river and makes the color of the river turn into red. Son river flows from Phong Nha cave and connects to Gianh river.
Along the two banks of Son river are large mountains. The motorboat will carry tourists running along the river. Sometimes, we will meet popular scenes like small fishing boats; bamboo hedges with the trunk bending like a fishing rod; children bathing and playing in the river; several herds of cows drinking water; some girls washing their hairs and clothes.
Phong Nha cave is 7,729 meters long. The entrance cave is in a trapezoid, about 10 meters high and 20-25 meters wide. After the motor boat is switched off, the boatman will use a pole to control the boat going inside Phong Nha cave. Entering the cave, you will realize that the scorching heat that covers the Central region during the summer Laos wind immediately disappears.
