The National Park of Phong Nha-Ke Bang was established in 2001
by the decision of the Prime Minister
to transform the National Park of Phong Nha-Ke Bang
into the National Park of Phong Nha-Ke Bang.
The name comes from two parts,
Phong Nha Cave and Phong Nha-Ke Bang Rock Forest.
This is a castle area with global significance.
Not only does it have the value of geothermal energy,
but it also has the value of biodiversity.
Phong Nha-Ke Bang is located in Phong Nha-Ke Bang,
about 200,000 hectares wide,
along the Vietnam-Laos border.
Much of the park's area
is connected to the National Park of Phong Nha-Ke Bang
of the People's Republic of Vietnam.
This area plays a very important role
in preserving biodiversity
because of its area and location
in the connection between the two regions.
The National Park of Phong Nha-Ke Bang
was established to protect
one of the two largest castle areas in the world
and preserve the North Chiang Son ecological system.
The park is characterized by rock formations,
more than 300 large and small caves,
rivers,
and rare plants
found in Vietnam and around the world.
In recent years, Phong Nha-Ke Bang
has been known by many people
as one of the most magnificent places in Vietnam.
With its beautiful landscape,
Phong Nha-Ke Bang
has captivated the hearts of many tourists.
It has gone through important construction periods,
and has continuously created
mountain ranges
due to the high elevation
and slope of the precipitates.
It plays a role as the cause
of all the causes
that create biodiversity
in terms of geography, geomagnetism,
hydrothermal network,
and biodiversity of caves.
The process of constructing the castle
has formed rivers,
caves,
caverns,
hanging caves,
tree-shaped caves,
and winding caves.
The caves of Phong Nha-Ke Bang
are divided into two main systems.
The Phong Nha system
consists of 9 caves
that flow into Song Son River,
and the Dong Vong system
consists of 8 caves
that flow into Chay River.
It has undergone many major changes
in geography and geomagnetism
over the centuries,
which has made the geography
here extremely complex.
Phong Nha-Ke Bang is a place
that displays impressive evidence
of the history of the Earth's crust.
It helps scientists understand
the geological history and geography
in the area.
Excavations have confirmed
that Phong Nha-Ke Bang
is one of the most distinctive
and beautiful models
for constructing complex characters
in Southeast Asia.
Therefore, UNESCO's
Cultural, Scientific and Educational
Organization has recognized
Phong Nha-Ke Bang National Park
as a World Heritage Site
with outstanding characteristics.
Phong Nha-Ke Bang is an outstanding model
that shows the main development
periods of the Earth's history.
Preserved as evidence of life
and geological processes
that are taking place,
it is meaningful in the process
of shaping landforms
or characteristics of geography
and geomorphology.
These are the outstanding values
of geomorphology
of Phong Nha-Ke Bang.
The area of Phong Nha-Ke Bang
is located in the west of Quang Binh
province, comprising two areas.
The area of Phong Nha-Ke Bang
is located in the north
and the area of Phong Nha-Ke Bang
is located in the south.
In general, the geography here
is distributed in a gradual direction
from the south to the north
and from the west to the east.
From the south to the north,
Phong Nha-Ke Bang has the highest
altitude, about 700 to 900 meters
above sea level.
From the west to the east,
Phong Nha-Ke Bang
is the watershed area
between the east and the west of Truong Son.
The Viet-Lao border area
comprises the top of Phong Nha-Ke Bang
with a height of 800 to 1000 meters.
In the area of Mu Gia,
there are also some peaks
of 1,200 to 1,600 meters.
Phong Nha-Ke Bang
lies in the An Ti mountain range,
a young mountain range
that has developed strongly
in the Kai No Roi period.
Therefore, the limestone blocks
in this area are characterized
by a rather strong geological
and geological rock.
The climate of Phong Nha-Ke Bang
is hotter and warmer
than other areas.
The above factors have made
the evolution of the caster terrain
here not exactly the same as elsewhere,
although this evolution
occurred with the same
disintegration mechanism
and destruction of geology.
Thus, many types
and types of caster terrain
have been created both on the surface
and below the deep cave.
The geological rock system
on the surface of limestone
has created conditions for water
to penetrate the blocks,
increasing the possibility of dissolution
due to the water containing
acids reacting with limestone.
The magnificent activity system
of Phong Nha-Ke Bang
was created by the process
of the construction of the cliffs.
Then, the process of geophysical
and chemical deformation
has intensified and disintegrated
over millions of years.
In the hot and humid climate,
the process of casterization
is very strong in strength
and speed of destruction.
Geological characteristics
of Phong Nha-Ke Bang reflect
the evolution of geological
and ancient world history,
geomagnetic evolution
and geological diversity
associated with the history
of the development of the earth.
Each stage of the development
of the earth is characterized
by a characteristic structure
called the architectural plateau.
According to the research
of scientists,
Phong Nha-Ke Bang is the total result
of five major stages
in the history of the development
of the earth's crust.
The late Ordovician stage,
Silur, is about 450 to 410 million years
before the original.
The Devon stage is about
410 to 355 million years.
The Carbon-Permian stage
is about 350 to 250 million years.
The Mesozoic stage
is about 250 to 65 million years.
The Cainozoic-Neogen stage
is about 23.75
to 1.75 million years
and the Quaternary
is about 1.75 million years.
From these research results,
scientists have confirmed
that the Phong Nha-Ke Bang area
still shows geological events
that prove the history
of the development
of the earth's crust
for 450 million years.
The complex construction
of the earth's crust
is the cause of all the causes
of the formation and destruction
of geosystems.
It is the evolution
of a geosystem
like today.
The geosystem
and its various components
are the determining factors
of the geosystem
and are also one of the factors
that determine the climate,
water, climate,
natural geography,
biodiversity
and the environment.
The Phong Nha-Ke Bang
is one of the largest
and relatively original
and not divided
in Southeast Asia.
This mountain
is over 1,000 meters thick
and mainly carbon-permian
with a high viscosity
and a thick layer.
This is a guarantee
for the evolution
of geosystems.
Initial discoveries
have shown that the caves
lie at different heights
and show that the Phong Nha-Ke Bang
has a long history
of geological evolution
and has gone through many periods.
This has been proven
by the multi-layered structure
of the caves.
The strong evolution
of geosystems
in terms of geosystems,
climate,
has created a rich geosystem.
The Phong Nha-Ke Bang
is now always open
to welcome tourists.
The Hien Hoa River
will take us to the Phong Nha-Ke Bang.
In the summer,
the river is clear
and gentle
and embraces the mountains.
The clear,
delicate water
flows into the river
as if following
all the souls of tourists.
In the rainy season,
even when the sky is gloomy,
sometimes the river
brings a red color.
That is because the water
follows too much red soil
and the wind
destroys the soil.
On the other side of the river
is Dai Son Gorge,
a part of the Phong Nha-Ke Bang.
30 minutes by boat
is also the time
for us to enjoy the land.
When the soul is wide open
following the river,
the Phong Nha-Ke Bang
is right in front of us.
From a distance,
we can see
the shape of the tunnel
close to the water
which makes us feel
that the boat
is not easy to get in.
When we get close,
everyone is surprised
by the vastness of the tunnel.
The cool air
makes us feel comfortable.
When the sun shines,
the temperature in the cave
is only 20 degrees Celsius.
The Phong Nha-Ke Bang
is like a giant thermocouple
of nature.
It is because the air pressure
is very different
between the inside and the outside.
The cave is so big
that it looks like a sky full of glass.
On top of it,
there are huge rocks
which make us feel
like we are in a monster's cave.
According to the southernmost governor,
the Phong Nha cave is also called
the cave of the gods
or the cave of the gods
which is located in Tien Coc mountain.
Since the early 20th century,
the Phong Nha cave has been visited
by French and British explorers
to conduct research.
But in the late 20th century
and early 21st century,
the discoveries of the Royal British Cave Society
and Vietnamese scientists
led to a comprehensive understanding
of the cave system
in Phong Nha-Ke Bang.
These research results
have been used as a basis
for the protection, planning
and development of tourism
as well as completing the documents
to be submitted to UNESCO
to be recognized as a World Heritage Site.
Nature is so clever
that it can understand the words
of thousands of things
to create a perfect balance.
Creation does not leave Phong Nha alone
but has added more life
to Phong Nha.
Located at a height of about 200 meters
on the Phong Nha cave,
Tien Son cave is 980 meters long
and does not intersect
with Phong Nha cave.
The way to Tien Son cave
is very beautiful
along the winding mountain range.
In the middle of the mountain range,
we can stop,
take a deep breath
and enjoy a peaceful landscape
with small caves.
In the middle of the winding mountain range
is the Chok River.
Put your feet in the cave
and you will feel like
you are stepping into the natural world.
Every place, every hideout
is a natural wonder.
Thousands of colorful light balls,
crystal-colored light bulbs,
colorful star-shaped stones
are floating in the air.
Clear eyes,
clear eyes,
every place is perfect.
The unique features of nature
are not lacking.
This place is the soft,
soft,
If Phong Nha,
the beautiful water palace,
where there is a king of water,
a fish fairy,
Tien Son is the opposite
of Ngoc Hoang and Tien De.
In fact,
Phong Nha and Tien Son
are a pair of twins,
a unified form of creation.
The wonder of Tien Son
has made tourists confused,
confused
because they don't know
which cave is more beautiful.
The cave system of Phong Nha Ke Bang
is the oldest in Southeast Asia,
and its formation is related to
the carvings created in the Tang Dynasty,
that is, at the same time
with Pha Tech San formed in the South.
The cave system here
was developed on
the largest limestone in Southeast Asia,
which is very old,
from the late 4th century to the 5th century.
Around the limestone,
the development of non-carbonate terrain
is the best condition for
the formation of limestone caves,
while increasing biodiversity
in the area.
Phong Nha Ke Bang
is nicknamed the King of Caves,
with hundreds of different
large and small caves.
These caves are mostly
in two main systems,
the Phong Nha cave system
with a total length of 5,000 meters
and the Vom cave system
with a total length of 36,000 meters.
Visit the World Heritage Site
Phong Nha Ke Bang,
visitors can freely choose
their tourist destination.
If you love the world of the ancestors,
come to Phong Nha cave,
one of the most magnificent,
or you can come to Tien Son cave,
the home of Thach Nhu.
In the future,
you can visit the Heaven Cave,
nicknamed the Queen of Caves,
or Son Dong,
the largest cave in the world,
just announced by explorers.
If you choose sports tourism
and nature exploration,
you can cross the Tien Son 40 km
to conquer the U Bo peak,
which is considered
the lowest point in Vietnam.
Here, I feel like
I'm in Sapa,
Ba Na or Dalat
with the fresh and cool air.
On sunny days,
visitors can take a look
at the ocean,
the white sand at the end of the sky
or the green forests.
That green color keeps running
and spreading endlessly
makes me feel like I'm floating
in the air and enjoying
the scenery around me.
More than ever,
you feel so close to nature
because of the scenic views
of the mountains and rivers.
If you want to come to nature
with mountains, forests and rivers,
I invite you to come back
to Thuong Ngoan,
where you can see
the fascinating ecotourism
of the Khe Bang family.
From the bottom of the earth,
the main water source of the lake
is flowing up.
You don't have to worry
when you enjoy this
beautiful and unique scenery.
The water flows up
from the bottom of the earth
and merges with each other
to create a beautiful river.
The flowing water
is the manifestation
of a river
in the cave system.
The ecological tourism
of the Nguoc Moc river
is located in the middle
of the high mountains
and the steep streams
coming out of the mountains.
The pure beauty
of nature
will bring the visitor
a relaxing, comfortable
and close feeling
of being in harmony with nature.
The large and small rocks
close to the entrance
of the Moc river
surrounded by the forest
and the wind
gently blowing
on the fragrant trees.
The endless forest flowers
will make you dizzy
as if you are lost
in the fairy tale
of the childhood.
The Nguoc Moc river
is an attractive
and wonderful
that will leave
to become an unforgettable impression of a magical natural landscape.
Along with the beautiful natural scenery,
Kẻ Bàng's house also carries the legendary Trường Sơn trail,
where the heroic deeds of the people are recorded.
Kẻ Bàng's house contains a warm and beautiful forest,
full of wild flowers, with many mysterious things of nature.
This is a place full of aesthetic, beautiful,
scenic, geographical, historical and biodiversity,
which is not found anywhere else.
That is why UNESCO has recognized Kẻ Bàng's house
as a World Heritage Site in terms of geography and biodiversity.
Although there have been some initial results about the geography of Cagster,
but due to the large area of the limestone,
the diverse geography of Cagster, both on the surface and under the cave,
mainly the long river cave,
there are still many unknown locations.
Studies and discoveries have only been carried out
at locations that can be reached relatively easily.
This shows the importance of the limestone block of Kẻ Bàng's house
to our understanding of Cagster areas around the world.
Thanks to the rarity of the terrain,
the diverse conservation of nature,
including the diversity of geosciences and biodiversity
in Kẻ Bàng's house is still very good.
With the global values of geography, geoscience and biodiversity,
as well as many other values that have been recognized,
Kẻ Bàng's house has enough conditions
to build a geological park in Vietnam.
The construction of a geological park
not only develops the tourism economy,
but also protects the environment sustainably.
Therefore, the conservation of Cagster landscapes
in the house of Kẻ Bàng
will bring great scientific and practical significance.
