The Phong Nha – Ke Bang Nature Reserve was created in 1999 and was renamed the Phong Nha Ke Bang National Park in 2001. The park derives its name from Phong Nha Cave, containing many fascinating rock formations, and Ke Bang tropical forests. The National Park contains terrestrial and aquatic habitats, primary and secondary forest, sites of natural regeneration, tropical dense forests and savanna and is rich in large, often spectacular and scientifically significant caves. The property contains and protects almost 200 km of caves and underground rivers making it one of the most outstanding limestone karst ecosystems in the world. The karst landscape is not only complex but also ancient, with high geo-diversity and geomorphic features of considerable significance.

The karst formation process has led to the creation of not only underground rivers but also a variety of cave types including: dry caves, terraced caves, suspended caves, dendritic caves and intersecting caves. The Phong Nha cave is the most famous of the system with tour boats able to penetrate inside to a distance of 1500m. The Son Doong Cave, first explored in 2009, is believed to contain the world’s largest cave passage in terms of diameter, height and volume.

The exploration of these most amazing caves Phong Nha Cave, Thien Duong Cave (Paradise Cave), Son Doong Cave, Hang En Cave etc. came into existence to bring a giant wave of tourism to not just Phong Nha – Ke Bang National Park but all of Vietnam.

Life in Phong Nha – Ke Bang National Park


Phong Nha has an unusual and special charm to itself. The simplicity of the lifestyle that the locals of Phong Nha lead, is truly beautiful to see and know about. Lots of money or a lack of it has never stopped the locals from sticking to their roots and smiling through all phases alike. The families live together, work together and constantly put their efforts towards a collective growth of Phong Nha. The days are spent working hard and the nights are spent relishing good food and chatter with loved ones.

The occupations of the Phong Nha locals are diversified and common at the same time! Some are involved in agriculture, some are involved in fish farming, some are involved in providing transportation services to visitors, some in providing wonderful accommodations, while some run restaurants for Phong Nha travellers to enjoy the authentic Vietnamese cuisine.

The Na Village on the other side of the majestic Son River has a majority of locals working as boatmen taking visitors to the ever glorious Phong Nha cave. This is one of the rather unconventional and important occupations in Phong Nha, in terms of the rapid development of tourism in the region.

Although the Phong Nha – Ke Bang National Park suffered in the past in the Vietnam War, the people of Phong Nha could fight through their adversities with the unconditional support of Mother Nature and got over the harsh times with intense determination. The natural beauty of Phong Nha could never be destroyed and it gave the people hope and happiness even in times of grief.

Tourism has changed the entire image of Phong Nha and it is now considered one of the premier holiday and travel destinations in the whole world, as travellers come here from every walk of life and go back with special memories.

A heart-warming story

To get a more realistic taste of the facts mentioned above, here’s an excerpt of Phong Nha through the eyes of a local boatman:

“My name is Giáo, I’m 60 years old and I’m a boatman making daily trips to the Phong Nha cave. My family has been living here their whole life and witnessed lots of ups and downs of Phong Nha village.

About 20 years ago, Phong Nha had suffered a lot even after the war ended. We, with our agricultural background, still lived in poverty with no electricity, transportation or stable incomes. It’s so unbelievable how things have changed. Now, thanks to the great development of tourism on our land, our lives have been majorly improved. We have electricity for the most part, living conditions in the town are way better than before and we earn an increased income from our boat jobs, together with our family’s fish farming & agricultural activities. My children could pursue better education and my family continues to live a peaceful life here in Phong Nha. It’s a wonderful feeling to think that there is such a big world outside of Phong Nha and people from every corner would visit us with so much love. It fills us with so much happiness, as we see Phong Nha gradually becoming a worldwide example for beauty & peace, and a land that welcomes everyone with open arms.”

How tourism transformed Phong Nha for the better

Despite a massive wave of tourism, Phong Nha is one of the few places on Earth that still hasn’t lost its tranquility. Phong Nha has been a game-changer for Tourism in Vietnam and attracts travellers from every corner of the world and diversified walks of life.


The standard of living of the locals has improved by leaps and bounds since tourism made its way into Phong Nha. Apart from the incredible generation of employment opportunities and monetary benefits for the Phong Nha locals, it has also brought Phong Nha closer to the rest of the world. Not the just friendly locals but even the kids grow up watching people from all over the world and communicating with them. Phong Nha has indeed become a global destination thanks to the development of tourism in the region and changed the lives of the Phong Nha locals for the best! Any Vietnam Travel itinerary or South-East Asia travel experience would be incomplete without a visit to this magical land.
