Phong Nha – Ke Bang area has a group of over 300 caves multi – shaped known as the “Kingdom of the cave”, where there is a mystery of wonders and attraction, a paradise for scientists in caves, explorers and tourists. Up to now, the British cave research association in collaboration with the Geography Department of Hanoi National University has surveyed more than 170 caves with a total length of hundreds of kilometers, which have been published on the journal of International Caves  – No. 48, July 1994 and valuated as one of the most beautiful sights with characteristics as follows: the cave with the longest underground river, the highest and widest entrance, the most beautiful sandbank and reef,the most beautiful undergroud lake, the most beautiful and widest dry cave, the most spectacular stalactites, stalagmites and longest water grottos. Among the caves, Phong Nha is really prominent with surveyed length of nearly 8 km, mainly with underground rivers, Vom cave (Arch cave)  is more than 15 km long, Paradise cave is 31.4 km which are included in the list of the caves with the longest underground rivers in the world.

Along with the miraculous cave system, the Trooc river, Chay river and Son river in  Phong Nha – Ke Bang region with the fresh blue streams winding among the rock mountains with forests, have created a poetic beauty as a magnificent water – color  painting.  

The primeval forest Phong Nha – Ke Bang with tens of top of mountains of more than 1,000m high, full of obstacles and no human footprints, is an attractive place for climbing and exploration. For instance, Co Rilata peaks of 1,128 m high, Co Preu of 1,213m high. Lying among the peaks over 1,000 m, suitable for ecological tourism and climbing such as mount Phu Sinh of 965 m high, Ma Ma of 835 m high. Especially, mount Ma Tac of 721 m high.

In  Phong Nha – Ke Bang National Park, there is still existing a primitive tropical forest, little affected, with the covering of  more than 96.2% and features a great biodiversity. In this region, there is according to the survey data, many endemic plant species of the limestone forest such as Chò nước (platanus kerrii), Cho Dai Nghiến (Burretiodendronhsienmu), Trầm Hương (Agarwood), Ba Kích, Sao ….vessel plants include  1,762 families, 511 stains, 876 species, of which 38 species are listed in the Viet Nam Red Book, 25 species listed in the IUCN Red Book (World Union for Conservation of Nature) and 13 endemic species in Viet Nam. Scientists also discovered many rare plant species in danger of extinction such as the Calocedrus rupestris, paphiopedilum spp and many other rare plant species.

In comparison with other conservation areas and national parks in Vietnam, the abundance of the animal species in Phong Nha-Ke Bang is rather high. The rare species, especially primates have been found with the highest number of the country.

             

Besides the vegetation and wild animals, Phong Nha – Ke Bang region is also the place where the highly valuable historical and cultural heritage of many ages have ever been and is currently existing such as archaeological heritages of prehistory, Cham culture, and ancient Viet, vestiges of the base of resistance war against the French of Ham Nghi king in late 19th century at Mai Rai mountain and well-known places such as Xuan Son ferry, Ho Chi Minh trail, the Quyet Thang road No.20 which have entered into the legend associated with brilliant feats and lofty sacrifice of Vietnam people in the war for independence and unification of the fatherland. 

In addition, in the Phong Nha-Ke Bang region live mostly  Chut – minority ethnic group, a few Viet and Bru-Van Kieu ethnic. In Quang Binh, there are about 3,500 heads  Chut-Sach, Chut-May, Chut-Ruc, Chut-Arem, Chut-Ma Lieng people who mostly scatter in Tuyen Hoa, Minh Hoa and a few in Bo Trach district. In Phong Nha – Ke Bang area, about 2,450 people of Chut minority ethnic present in Minh Hoa and Bo Trach districts, mostly of them are above mentioned clans, except Chut-Ma Lieng

The ethnic people of the Chut ethnic group (named as Chut Poong) and their languages that is guessed to be divided from first Viet-Muong language in about century V-VI. Name “Chut” means ‘Rem Da in Vietnamese”, means “Limestone curtain in English”.

The Chut’s people is now agriculturalists, but they used to earn a living by hunting, picking and live in extremely backward and wild conditions. Most of all Chut minority ethnic lived on shifting cultivation and wandering hill tribes in forests and caves … Today, spiritual and material life of the Chut ethnic group has been improving step by step. The Chut’s people culture that is the object of study of many scientists and it is also the attractive places for minority ethnic people cultural tourism in Phong Nha-Ke Bang Area.

During the past years, Phong Nha – Ke Bang as become a favorite tourism place of  the tourists. The number of tourists has increased more and more, especially from the time when Phong Nha – Ke Bang National Park was recognized as a World Natural Heritage. Together with My Son holy land, Hoi An ancient town, Hue ancient capital, Phong Nha – Ke Bang World Natural Heritage formed and opened an original tourist route “the Central Heritage Road”, which will create the atraction to tourists.

Viet Nam’ Government is compiling scientific documentation to submit to UNESCO to consider recognition Phong Nha – Ke Bang National Park as a world natural heritage for biodiversity a second time.

At a conference held in Bonn, Germany, the UNESCO World Heritage Committee approved the addition of two natural sites in its World Heritage List – the Phong Nha – Ke Bang National Park in Viet Nam and the Cape Floral Region Protected Area in South Africa.

 

It is the second time that the Vietnamese park received UNESCO recognition, the first time in 2003 for its geological and geomorphologic values.

In 2009, information of the park’s biodiversity was submitted to the UN agency, but the files were returned. Viet Nam was asked to solve issues related to the integrity, protection and management of the heritage.

 

The site’s new profile includes more geological and geomorphological data. Since 2012, the park area increased from 85,754ha to 123,326ha under a decision by Prime Minister Nguyen Tan Dung to adjust its boundaries.

 

The new information on the park’s biodiversity and ecological and biological processes won it the latest recognition.

 

The UN agency said: “With this extension, the site shares a boundary with the Hin Namno Nature Reserve in the People’s Democratic Republic of Laos.

 

“The Park’s landscape is formed by limestone plateaux and tropical forests. It features great geological diversity and offers spectacular phenomena, including a large number of caves and underground rivers.

 

“The site harbours a high level of biodiversity and many endemic species. The extension ensures a more coherent ecosystem while providing additional protection to the catchment areas that are of vital importance for the integrity of limestone landscapes.”

 

The characteristic of this national park are its karsts that are millions of years old, and said to be most valuable in Southeast Asia. It has majestic landscapes with a spectacular cave system, abundant biological diversity and many historical and cultural relics, and underground rivers.

 

The park, located in Bo Trach district, Quang Binh province, is home to nearly 2,934 species of fauna and flora.

 

In 2014, Quang Binh welcomed around 2.8 million tourists, including 43,000 foreigners, an increase of 129 percent compared to the previous year.

 

In the first three months, the number reached more than 56,000, and the province expects to welcome a total of 3.3 million guests this year.

 

A cave festival entitled “Quang Binh – Kingdom of the Caves,” will be organised from July 15 to 21.

 

Many interesting activities such as the launch of new tourist destinations, promotions and tourist discounts and farm trips will be held during the event which is part of efforts to promote local culture, tourism and the uniqueness of the caves to attract both international and domestic investors and tourists.

The management board of Phong Nha – Ke Bang National Park on December 20 said that U.S. Travel Channel has finished a TV report exploring the imposing landscape of caves on Ke Bang Limestone Mountain and surrounding areas.

The channel has filmed En Cave – the third largest cave in the world and Tu Lan Cave in the north central province of Quang Binh.

 

In a meeting with the national park’s managers, Travel Channel representatives said they hoped to introduce beautiful nature of the national park to visitors from hundreds of nations and territories.

 

Phong Nha – Ke Bang National Park is home to the world largest cave Son Doong which was discovered in April, 2009 and several of other caves in Quang Binh.

 

With assistance from local men, the British Royal Cave Research Association has explored the cave system in Phong Nha – Ke Bang since 1990.

Introducing Phong Nha-Ke Bang National Park

 

Designated a Unesco World Heritage site in 2003, the remarkable Phong Nha-Ke Bang National Park contains the oldest karst mountains in Asia, formed approximately 400 million years ago. Riddled with hundreds of cave systems – many of extraordinary scale and length – and spectacular underground rivers, Phong Nha is a speleologists’ heaven on earth.

Its collection of stunning dry caves, terraced caves, towering stalagmites and glistening crystal-edged stalactites represent nature on a very grand scale indeed, and are beginning to create a real buzz in Vietnam, as more and more riches are discovered.

 

Serious exploration only began in the 1990s, lead by the British Cave Research Association and Hanoi University. Cavers first penetrated deep into Phong Nha Cave, one of the world’s longest systems. In 2005 Paradise Cave was discovered, and in 2009 a team found the world’s largest cave – Son Doong. Huge caverns and unknown cave networks are being discovered each year.

Son Doong Cave

Above the ground, most of the mountainous 885 sq km of Photoing Nha-Ke Bang National Park is near-pristine tropical evergreen jungle, more than 90% of which is primary forest. It borders the biodiverse Hin Namno reserve in Laos to form an impressive, continuous slab of protected habitat. More than 100 types of mammal (including 10 species of primate, tigers, elephants, and the saola, a rare Asian antelope), 81 types of reptile and amphibian, and more than 300 varieties of bird have been logged in Phong Nha.

 

Until recently, access to the national park was very limited and strictly controlled by the Vietnamese military. Access is still quite tightly controlled for good reason (the park is still riddled with unexploded ordnance). Officially you are not allowed to hike here without a licensed tour operator.

 

You can however travel independently (on a motorbike or car) on the Ho Chi Minh Highway or Hwy 20 that cut through the park. Sights that can be visited include the astounding Paradise Cave, turquoise river, ecotrail of Nuoc Mooc and a war shrine known as Eight Lady cave.

 

The Phong Nha region is changing fast, with more and more accommodation options opening. Son Trach village (population 3000) is the main centre.

Air Travel to Phong Nha

 

 

HANOI TO/FROM PHONG NHA
It is relatively easy to reach Phong Nha from Hanoi and vice versa with a number of transport options including train, bus and of course by flight. Most bus companies will now stop directly in Phong Nha, and taking a bus is therefore becoming a popular choice amongst travellers as it saves on the additional transfer required from Dong Hoi (closest train station and airport to Phong Nha).

 

Air Travel to Phong Nha
Of course, the easiest mode of transport is to take a flight here from Hanoi, it being just a 50 mins flight. However, you have to factor in the time travelling to the airport (1 hour from old quarter) and the fact there are only 4 to 5 flights per week. It is best to check the Vietnam Airlines website ahead of time to ensure you can catch a flight on your desired travel dates, otherwise we recommend the train or bus to save your travel days. If you take a flight you will have to book a transfer from Dong Hoi to Phong Nha.

HO CHI MINH CITY TO PHONG NHA
Ho Chi Minh City, also still known by its former name of Saigon, is the biggest city in Vietnam. It is a focal point for those looking to see highlights such as the Mekong Delta, and it’s also a hub for international travel.

 

The only practical way to journey between Ho Chi Minh City (HCMC) and Phong Nha is to take a flight with Vietnam Airlines (or from February, Jetstar Pacific Airlines) to Dong Hoi City (located 45 mins drive from Phong Nha). The tickets cost between $80 and $120 each way and please note the flights are not daily.

 

The bus and train journeys are both just too long to be viable options for those wanting to get quickly between the two cities. Alternatively, for those on a budget but who have a little bit more time, it’s common to find that the cheapest flights are often available between HCMC and Da Nang or Hue (versus direct to Dong Hoi). From Da Nang or Hue, one can find a train to get to Dong Hoi, or even a bus to Phong Nha directly.

 

Travel to Phong Nha by Train

 

 

 

Trains run from most major coastal cities up and down Vietnam and they can be a fabulous travel experience.. If you are taking an overnight train, try to book a soft-sleeper cabin (4 beds per cabin) or even a hard-sleeper (6 beds per cabin instead of 4) for the most comfortable journey. If you book a train ticket to Dong Hoi, you will still need to arrange a transfer from Dong Hoi to Phong Nha.

It is important to select a train with an arrival time in Dong Hoi at least 2-3 hours before your tour departure, as you will need to still make the 45 mins journey by taxi/private transfer to Phong Nha (additional VND 660,000 for transfer from Dong Hoi). We recommend the following trains from Hanoi to Dong Hoi:

 

• SE1 – departs Ha Noi at 7:30 PM (19:30) and arrives the following morning in Dong Hoi at 5:35 AM

 

• SE19 – departs Ha Noi at 8:10 PM (20:10) and arrives the following morning in Dong Hoi at 6:10 AM:

 

• SE4 – departs Dong Hoi at 7:52 PM (19:52) and arrives the following morning in Ha Noi at 5:30 AM

HUE TO/FROM PHONG NHA
Hue is located just a few hours drive from the jungle and caving capital of Vietnam. It is a relatively convenient route with trains and buses of offer from a number of companies, as well as it being a short drive by private transfer if you preferred

 

Hue is just a short 4-hour train journey from Dong Hoi and is a popular city to visit before or after one of our caving adventures. However, the connections in the late evening or morning are not great and would have you arriving in Dong Hoi at a bleary-eyed 1:00 AM or 04:30 AM, making it difficult to check in to any hotel.

 

We would suggest arriving the day before if you intend on taking a train from Hue to ensure you have plenty of rest before your jungle and caving adventure. We would therefore recommend the following trains from Hue to Dong Hoi.

• SE2 – departs Hue at 3:31 PM (15:31) and arriv

es in Dong Hoi at 6:30 PM (18:30)
• SE4 – departs Hue at 4:47 PM (16:47) and arrives in Dong Hoi at 7:37 PM (19:37)

• SE5 – departs Dong Hoi at 7:40 PM (19:40) and arrives in Hue at 10:42 PM (22:42)

Of course, you have quite a few more options if you choose to stay an additional night in Phong Nha, with some early morning trains departing Dong Hoi to Hue at 5:50 AM, 6:28 AM and 7:40 AM. Don’t forget you will need to arrange your transfer from Phong Nha to Dong Hoi in advance if you plan on making your early morning train.

 

DA NANG (HOI AN) TO/FROM PHONG NHA
Da Nang is the biggest city in central Vietnam with beautiful beaches, mountains and a 45 mins drive from the UNESCO world-heritage town of Hoi An. It is a 7 hour train/bus journey between Da Nang and Phong Nha.

 

We recommend arriving the day before your tour if you are taking the train from Da Nang to ensure you get a good nights sleep and not arriving too early in the morning. Do not forget if you are travelling on the train to Dong Hoi, you will need to book an additional transfer between Dong Hoi and Phong Nha (VND 660,000 each way).

 

• SE2 – departs Da Nang at 12:46 PM and arrives in Dong Hoi at 6:30 PM (18:30)
• SE4 – departs Da Nang at 2:13 PM (14:13) and arrives in Dong Hoi at 7:37 PM (19:37)

• SE3 – departs Dong Hoi at 7:40 AM and arrives in Da Nang at 1:00 PM (13:00)

All buses are becoming increasingly popular with most companies now stopping directly in Phong Nha (rather than 45 km away in Dong Hoi). If you are heading down from Hanoi you will arrive at around 4:00 AM giving you enough time for breakfast before the start of your trekking adventure. Most buses also depart around 9:00 PM giving you enough time after your tour to relax and enjoy dinner in one of the local restaurants before taking off. Buses connect Phong Nha with Hanoi, Ninh Binh, Hue, Da Nang and Hoi An.

Phong Nha Cave

 

Phong Nha Cave

The mouth of Phong Nha cave with underground river
This cave, from which the name to the whole system and the park is derived, is famous for its rock formations which have been given names such as the “Lion”, the “Fairy Caves”, the “Royal Court”, and the “Buddha”. This cave is 7729 m long, contains 14 grottos, with a 13,969 m-long underground river. The scientists have surveyed 44.5 km of grottos in this cave so far, but tourists can only penetrate to a distance of 1500 m.

Phong Nha cave tours
Phong Nha cave tours

Phong Nha Cave, like most of the caves in this area, has been continuously shaped by the Chay River. As one gets farther into the cave, the more illusory the stalactites and stalagmites look as they glitter when bright light is shone on them. The Son River flows into the mouth of the cave and keeps flowing underground, where it is referred to as the Nam Aki River, then this river emerges at a site 20 km to the south near Pu Pha Dam Mountain. The main Phong Nha cave includes 14 chambers, connected by an underwater river that runs for 1.5 km. Secondary corridors branch off in all directions. The Outer Cave and some of the Inner Caves have roofs that tower between 25 and 40 meters above the water level. From the 14th chamber there may be other corridors leading to similarly large chambers, but this area proves more dangerous for explorers because of the ongoing erosion of the limestone of the cavern. The Shallow Cave is located 800 meters from the cave mouth, where there is a spectacular landscape of sand and rock. Stalactites and stalagmites jut out like strange trees, exciting visitor’s imaginations.

 

Notable caves and grottoes in the Phong Nha Cave system include:

Dark Grotto (Hang Tối): located upstream of Son River running to the branch of Chay River on the left. This cave is 5,258 m long and with a height of 83 m. The entry is high and wide with heavy forest around the cave mouth

 

E Grotto (Hang E): a 736 m-long grotto accessible by the Hồ Chí Minh trail

 

Cha An Grotto (Hang Chà An): a 667 m-long grotto, with the width of 15 meters

 

Thung Grotto (Hang Thung): This grotto has an underground river of 3351 m, with the height in some part exceed 133 . This river receives water resources from Rao Thuong

 

En Grotto (Hang Én): a 1645 m long, 78.6 m high grotto

 

Khe Tien Grotto (Hang Khe Tiên): located south of Phong Nha, this grotto is 520 m long.

 

Khe Ry Grotto (Hang Khe Ry): located south of Phong Nha. The grotto is where the long Khe Ry stream (13.817 km or 8.585 miles) runs out

 

Khe Thi Grotto (Hang Khe Thi): a stream originating from the mountain, running underground the grotto
