The incredible landscape, the breathtaking views inside Son Doong have exceeded the imagination and creativity of countless artists and tourists.
Having been recognized as the natural world’s largest cave, Son Doong itself contained a lot of amazing secrets which many professional scientists still have not explained yet.
In general, Son Doong was created 2-5 million years ago by river water eroding away the limestone underneath the mountain where the limestone was weak, the ceiling collapsed creating huge skylights…
Today, Son Doong also becomes such an attractive destination that most of Western tourists are willing to pay the price of 3.000USD (equivalent to 63,6 million VND), however, they still have to wait until 2016 as the tours to Son Doong have been fully booked with no slots left. Anyway, how much do you know about this wild, secret and beautiful cave?
- Son Doong was discovered in a rainy day
In 1991, a local man named Ho Khanh discovered Son Doong by chance when he hidden himself in the cave to avoid rain and being wet. However, it was not until the year of 2009 when the British Royal cave Association approached this place to investigate that Ho Khanh revealed them about the existence of Son Doong.
It is extremely difficult to find the cave entrance hidden deeply in the forest due to its far away location from the national road so Son Doong cave is impossible to observe with Google Earth. Guided by Ho Khanh, the exploration team was able to go deeper inside the cave to take photograph, measure and collect the scientific data. Ho Khanh has described that: “just when set foot to the cave entrance, I felt clearly a cold wind blowing from the deep cave with the sound of the wind wailing through the cliff make me feel my blood freeze.”
- Son Doong can contain a 40-floor building
Son Doong Cave, officially discovered on April in 2009, is more than 200 meters wide, 150 meters high, and at least 6.5 kilometers long, though the explorers said they were unable to explore it fully. British explorers have recently discovered that So Dong is much larger than the world’s biggest known cave. However, the actual length of Son Doong may be longer than the one that scientists have revealed. Cavers of British cave association have not been able to conquer it due to the limited technical condition.
As a matter of fact, Son Doong has exceeded Deer cave of Malaysia’s Gunung Mulu national park which used to be recognized as the world’s largest cave before Son Doong.
Additionally, some sections inside the cave have their size up to 140×140 meters in which there are some 14-meter stalactite pillars. Photographer Casten Peter used to take a section of cave with the width of 91,44 meters, the cave arch with the height of 243,84 meters, that is, Son Doong can contain a 40-floor building inside it.
- It was taken shape 5 million years ago.
According to some scientific document, Son Doong was taken its shape when river flew across the limestone area which was buried along a fault line. Millions years bypassed, the river flows eroded and created a long mountainous underground tunnel. The ceiling part collapsed creating the big holes where the stones are soft enough and then after a long time, they became a giant cave arch.
- Son Doong Cave – The world of botanical diversity
Because the ceiling part of Son Doong cave was collapsed centuries ago, its entrails have a fresh wood, named as Eden by explorers. This wood is home to many monkey groups, crows and bats. Many types of ferns, palms, and green liana cover Son Doong from inside to outside. Many ancient lakes, waterfalls, and rivers located in the cave have created the marine algae. Especially, many explorers also discovered a type of pearl taken shape during the dribble of water, creating calcium crystal in each grain of sand.
- Why the number of tourists to Son Doong has to be limited
The reason Son Doong cave limits its tourists is that the government wants to protect the environment and the natural landscape. Currently, many secrets about the world of plant and animals inside the cave have not been explained thoroughly yet. So Son Doong cave says welcome to professional explorers, biological specialists rather than curious tourists. So unique and wonderful it is that young tourists with “itchy feet” will always be willing to pay a large amount of money to set foot here despite the difficult terrain and condition here. Anyway, if you really feel interested in it, don’t hesitate to prepare for a trip to Son Doong, it will be an amazing experience in your life.
