II. Highlights of Phong Nha-Ke Bang

Phong Nha-Ke Bang takes pride in its stunning nature that you may have to hold your breath on contemplating.

1. Rivers and Streams

Here, there are the charming Son and Chay Rivers, (the two longest underground ones in the Phong Nha-Ke Bang), gently flowing in the middle of the two sides’ reed and green bamboo rows. Most of the caves here have been shaped by those two rivers. The Son River flows into the mouth of the Phong Nha cave, which is the only point where it emerges in around 20 km. 

Also, there are more than ten spectacular streams, springs and waterfalls in Phong Nha-Ke Bang area, namely Gió waterfall, Madame Loan & Chài waterfall, Mọc stream erupting from a limestone mountain range, and Trạ Ang stream. 

Far far away can you see the enchanting pure Bong Lai Lake and Chai waterfall, adorned with a number of dark violet flower baskets blooming in the warm weather. Some tourists ever uttered: “Wow! Heaven!” since the scenery is so much romantic and marvellous!

2. Limestone Mountains

The Park also contains two dozens of mighty limestone mountains with over 1,000 m in height. Some of the most noteworthy peaks are the Co Rilata Peak with the height of 1,128 m and the Co Preu Peak with a height of 1,213 m. 

Non-karst topographic area accounts for a low percentage, distributing mainly in outer circle of limestone in the north, northeast and southeast of this national park. The height of these summits varies from 500-1000  m with the deep divisions. The grandiosity and uniqueness of the limestone mountain ranges that only can be found in Phong Nha-Ke Bang is of great attraction to tourists.

3. Flora and Fauna

The Ke Bang primary jungles have been home to 98 families, 256 genera and 381 species of vertebrates, many of which are listed in the Vietnam and World’s Red Book. If you are bold enough, you can go further into jungles to see by yourself these lively rare animals, Gecko, Macaque, and so forth. Watching them closely and directly is somehow thrilling but extremely interesting!

Besides, for those fond of plants, it’s good news that the tropical jungles have a huge number of tropical trees, grass, bush on limestone rocks and soil mounts, sindora trees, rattan and bamboo forest, and the nation’s greatest Calocedrus rupestris. It has 140 families, 427 genera, and 751 species of vascular plants, of which 36 species are listed in Vietnam’s Red Data Book.

4. Phong Nha Cave

Penetrating to a distance of 1,500 m inside Phong Nha Cave, tourists may go from surprise to surprise! Up to now, there are more than 300 caves that have been discovered, and still continuously shaped by the Chay River. 

The Son River flows into the mouth of the cave and keeps flowing underground, where it is referred to as the Nam Aki River. The main Phong Nha cave comprises 14 chambers, connected by an underwater river that runs for 1.5km. 

Notable caves and grottoes of Phong Nha include Phong Nha Cave, Dark Grotto, E Grotto, Cha An Grotto, Thung Grotto, En Grotto, Khe Tien Grotto , Khe Ry Grotto, and Khe Thi Grotto. The most famous one is Phong Nha cave, which has been considered as “First-ranking Cave Wonder” for its world’s most beautiful stalactites and longest rivers by the Brishtish Royal Geography Association. 

Sitting on your boat along the Son River into the Cave, listening to the wind whistling as if in a Cathedral, you may be unable to return! As you get farther into the cave, the more illusory the stalactites and stalagmites look as they glitter when bright light is shone on them.  

Here you can contemplate the splendid landscape of the ancient huge teeth-like stalactites falling and stalagmites roughly rising. The stalactite brilliant light stretches throughout the cave as a beautiful silk full of colors.

Each of the cave contains its own mysterious and miraculous secrets of the eternal dark Caves, stimulating and absorbing tourists to come and discover by themselves!

III. Cultural Heritage of Phong Nha – Ke Bang National Park

The oldest evidence of human occupation of the area are Neolithic axe heads and similar artefacts found in some of the caves. There are some relics of Ham Nghi King, a final King of the Nguyen dynasty before the French colonial period, at the Maria Mountain in the north of the Park. 

Currently the Arem, Ma Coong and Ruc ethnic groups live in two villages in the core zone of Phong Nha-Ke Bang National Park. Until 1962 these indigenous people lived in the forest in houses made of bamboo and leaves or in the caves, living from forest products and hunting. They used simple tools and their clothes were made from the bark of a toxic forest tree (Antiaris toxicaria) and lianas.

Since 1992 the Government of Vietnam has set up two new settlements for these 475 people, who are the two smallest ethnic groups in Vietnam. These people are familiar with a number of economically valuable species, especially precious timber such as Mun and Hue (Diospyros spp., Dalbergia rimosa), and oil-extraction from species such as Tau (Hopea hainanensis) and many medicinal plants. 

The Phong Nha Cave has long been a site of religious and tourist importance, with an old Cham Temple discovered in the cave and it was a site of worship in the ninth and tenth centuries. During the war with the USA the Phong Nha – Ke Bang forest and caves were a garrison and weapons store for the Vietnamese army.

IV. Conservation Values

Phong Nha-Ke Bang National Park is of high conservation value as one of the largest areas of intact forest habitat remaining in Vietnam. As part of a continuous forest block with the neighbouring Him Namno Biodiversity Conservation Area in Laos, it forms one of the largest areas of forest on limestone karst in Indochina. 

The presence of tall lowland forest, which is regionally threatened as a habitat type in the National Park increases the area’s conservation value.

V. Tourist Activities in Phong Nha-Ke Bang National Park

The number of tourists has increased dramatically since the park was listed in UNESCO’s World Heritage Sites. Tourism activities in the area are the responsibility of the Trading and Tourism Department of Quang Binh province, with 280 international standard rooms in the province and 8 vehicles with capacities of 4 to 15 seats for tourist transportation. The forest guards of Son Trach commune in Bo Trach district are placed on tourist security duty.

Quang Binh Province has invested into upgrading the Phong Nha-Ke Bang visitor site to turn it into one of Vietnam’s major tourist destinations.

Multiple eco-tourist projects have been licensed for development and the area is being heavily developed by the province to turn it into a major tourist site in Vietnam. 

Phong Nha-Ke Bang is part of a tourism promotion program called: “Middle World Heritage Road” which includes the ancient capital of Hue, the Champa relics of My Son, the city of Hoi An, nha nhac and the Space of Gong Culture in the Central Highlands of Vietnam.

Some tourist activities in Phong Nha-Ke Bang National Park are organized by local travel agencies and vary in form:

• Tour for expedition of caves and grottoes on boats and with professional cave expedition means

• Ecotourism, discovering the flora and fauna in this national park in the Ke Bang Forest

• Mountain climbing: There are extreme sloping mountains here with a height of over 1,000 m, which is a real challenge for adventurous climbers

In order to facilitate the increasing flow of tourists to the site, the Dong Hoi Airport was constructed and is due to be operational at the end of 2008.
