The biggest cave. What is the largest cave in the world

In 1991, a unique Son Doong cave was discovered in Vietnam (near the border with Laos), recognized as the largest and most beautiful cave in the world. Its length reaches nine kilometers, its height is 150 meters, and its age is several million years. Some 150 halls, which would take months to explore, were discovered in the cave.

In 2009 and 2010, speleologists who arrived from the UK worked in Shondong Cave. They spent two weeks underground and described in detail unusual phenomenon nature. The scientists were amazed by the deep chasms and magnificent stone columns that they encountered along the way. They are confident that modern skyscrapers will fit in the halls of the cave.

Path to Son Doong Cave

In 2015, the cave was officially visited by the first non- large group tourists, each of whom did not spare three thousand dollars for a dangerous trip to the dungeon. They had to go down an 80-meter rope and use climbing equipment in dark labyrinths to see 70-meter stalagmites and unusual pearls, underground clouds, jungles and amazing animals, and also hear the roar wild river, the waters of which formed large rooms in the rocks and carved rock paintings.

How to get to Shondong Cave?

To get to the entrance to the cave you need to move through the impenetrable jungle for more than a day, which not everyone can do. Only the hardiest tourists descend into the cave. Each group of eight people is accompanied by experienced guides and speleologists. Below, a fire is made and food is prepared, and a tent city is created. Tourists will find a multi-kilometer walking route crossing water obstacles.

Always connected with caves large number secrets and riddles, because this is - the whole world magic, silence and silence. Even in ancient times, caves were used to shelter humans and animals, and some were even considered the abodes of the gods. In nature, no two caves are identical, because some have lakes, others have halls with grottoes, wells, glaciers and waterfalls. Many thousands of years rainwater destroyed the stone, forming stalactites and stalagmites of bizarre shape. In some caves, calcite forms in the form of pearls, flowers, and thin twigs that crumble at the slightest touch. We present to your attention the rating of the most amazing and beautiful caves peace.

1. Cave of Giant Crystals, Mexico

A cave of giant crystals in Mexico was discovered by ordinary miners working in the south of the country. At the depth of a three-hundred-meter shaft, they discovered a cave literally strewn with huge crystals from the inside. The crystals in the caves are translucent, and their color varies from bright white to golden. The crystals are rectangular or cylindrical in shape, and their length reaches several meters. The base of the cave is stone, which indicates its ancient origin. The huge crystals in it were formed by nature over several million years. Apparently, the Crystal Cave room used to be full rock which was gradually washed away groundwater, after which such unusual formations remained.

2. Na Pali Coast Cave in Kauai, Hawaii

The Hawaiian island of Kauai was created more than 5 million years ago as a result of volcanic activity in the area. One of the island's most spectacular attractions is the Na Pali Coast. Here the rocks practically hang over the sea, and on their surface grow exotic plants and various birds nest. In addition to the picturesque volcanic mountains and evergreen beaches, tourists are attracted here mysterious caves. For many centuries sea ​​waves methodically ground out volcanic rocks, thus forming the caves of Hawaii. In the caves you can enjoy virgin nature and sea views.

3. Melissani Cave, Greece

About located on greek island Kefalonia, the Melissani cave, was forgotten for several centuries and was only remembered in 1951, when the Greek Giannis Petrohelios rediscovered and discovered it. After all, even in Greek mythology, this cave was mentioned as the home of nymphs. The reason for such a wild imagination of the ancient Greeks is quite clear - the cave with its turquoise lake, surrounded by a dense forest, looks truly fabulous. The Melissani cave has a stone base on which there are shallow azure waters, at the top there is a huge stone dome with a huge hole through which one gets into the depths of the cave. sunlight, creating amazing reflections on its walls. The entrance to the Melissani cave is also very picturesque - it is overgrown with greenery, and the “door” is decorated with natural brownish stone “plaster”.

4. Skocjan Caves, Slovenia

One of the most famous karst cave systems on our planet are the Škocjan Caves. On the beautiful Kras plateau, located in the southwest of Slovenia, are these wonderful caves, officially recognized as a nature reserve and site World Heritage. The Škocjan Caves owe their appearance to a local river flowing through it called “River”, which over the centuries has “cut down” the caves in the karst deposits. However, as a result of water erosion, several vaults of the cave collapsed, forming the “Mala Dolina” and “Velika Dolina” karst sinkholes, separated by a natural bridge. On the territory of the “Velika Dolina” the River goes underground, appearing on the surface after 34 kilometers already in Italy. In addition, on the territory of the Škocjan Caves there are many dangerous sinkholes, sinkholes and small waterfalls. The largest European grotto, the Martel Hall, is also located in the caves.

5. Marble Caves in Chile Chico, Chile

High in the Andes lies one of the deepest lakes in the world - Lago General Carrera (Chilean name) or Lago Buenos Aires (Argentine name), since the lake is located on the border of Chile and Argentina. Not far from the Chilean city of Chile Chico are the famous Marble Caves. Although the walls of the caves are not made of marble at all, but of limestone, against the backdrop of turquoise water its vaults, which have white and blue tones of color, look very impressive. Thanks to this natural beauty, thousands of tourists come to see the Marble Caves every year. Small pleasure boats bring tourists here, allowing them to see all the splendor of the colors of the cave, as well as look into the natural windows, as if they had melted in the walls of the labyrinth of Marble Caves - boats can no longer pass there. In addition to the amazing Marble Caves, fishing lovers also come to the lake, because its waters are rich in trout and salmon, as well as some other types of fish.

6. Mammoth Cave in Kentucky, USA

Mammoth Cave is located in American state Kentucky. This unique karst cave has a unique microclimate. The cave was discovered about 4,000 years ago, and remains of ancient torches are still found in it. The cave was used by local tribes for various purposes. American scientists have discovered the mummy of a man who died in this cave more than 2,000 years ago. After numerous studies, scientists came to the conclusion that people were mining gypsum here. Found in an underground river rare species shrimp, crayfish and blind fish. In addition, flocks live in the cave bats. Already from the end of the 19th century, Mammoth Cave became a tourist attraction, for which purpose electric lighting was installed along its entire length. However, if you wish, you can walk through the cave as in ancient times - with a paraffin lamp.

7. Prices of the Yucatan Peninsula, Mexico

Coenotes are peculiar formations in caves that appear in rocks under the influence of water. South of the Mexican resort of Cancun, located on the Yucatan Peninsula, there is one of the most beautiful cenotes. According to some data, in ancient times Yucatan was an underwater reef. After the water left, huge caves remained. The caves and grottos of Yucatan are completely underground. There are no land rivers on the peninsula - they all flow underground. The Mayan people once considered cenotes sacred and drank water from them during religious ceremonies. Tourists from all over the world come to Yucatan to swim, dive and admire the underground landscapes. And ancient stalactites and stalagmites make underwater world truly fabulous. Through the cracks of the caves, sunlight penetrates into the cenotes, giving them a special beauty.

8. Blue Caves, Greece, Zakynthos Island

Zakynthos, one of the largest Greek islands, is home to the amazing Blue Caves. The island has become popular among tourists due to its picturesque surroundings, including beaches and villages. In the village of Volaims there is the Blue Cave, which can only be reached through the sea, as is the case with most of the island. If you visit the Blue Cave at sunset or sunrise, you can enjoy the blue color of the sky and ocean reflected in it. For many years water erosion, the rocks took on the appearance of amazing natural arches. Thanks to the unusual light effects of the Blue Caves, this place is one of the most visited in Greece. In addition to the beautiful caves, Zakynthos has a famous beach, considered one of the best in the world.

9. Fingal's Singing Cave, Scotland

Over many centuries, on the island of Staffa (the island belongs to the Inner Hebrides group of islands) in Scotland, rain and sea formed one of the largest caves in the world - the Singing Cave of Fingal. The cave owes its name to the famous Scottish poet James Macpherson. According to legend, the giant Fingal, in order to connect Scotland and Ireland, built a dam along which a huge giant walked into his home, while Fingal lay down to rest before the battle with him. However, his wife turned out to be resourceful and said that it was the baby, the son of Fingal, who was sleeping. The huge giant imagined the size of this “baby’s” father and ran away in fear, destroying the dam behind him. According to legend, Staff Island is part of this dam. The second reason for the name of the cave is the Geltish meaning of the phrase “Cave of Melodies”. The name was given to the cave due to the fact that during the surf, the cave hall repeatedly repeats the sounds of the sea, as if it were singing!

10. Skaftafell Ice Cave, Iceland

Surprisingly beautiful structures - ice caves - often form on the edge of glaciers. In Iceland, on the lagoon of the Svínafellsjökull glacier, there is the famous Skaftafell Cave. Over the past centuries, the glacier has been compressed so much that there are almost no air bubbles, due to which almost all sunlight is absorbed, except for the blue fraction visible inside the cave with the naked eye. Although such blue ice is only possible when washed away top layer glacier, for example, in winter. However, similar light occurs in floating icebergs and other ice caves. The Skaftafell cave has a seven-meter entrance on the shore. At the end the cave narrows to one meter. However, visiting ice caves is not safe, as it is constantly transforming and can collapse at any time. Only in winter is visiting such caves relatively safe. Because ice caves move with the glacier, cracking sounds can often be heard inside them.

Caves are underground cavities that communicate with the surface by one or more

inlets. The largest caves have complex systems of passages and halls, often with a total length of up to several tens of kilometers.

Today we will visit some mysterious caves.

Limestone cave Tham Lod. This is one of the most ancient caves in Thailand. It is very popular among archaeologists. A human skeleton that was more than twenty thousand years old was found here. Visitors to the cave will be able to see the dwelling primitive people. Caves were generally used by ancient people as comfortable dwellings.

Inside this cave, the walls are covered with massive formations over 20 meters high, which make you feel very insignificant in this world. There is no artificial lighting in the cave, so you need to move around inside with a flashlight. The very name of the cave - Nam Lod, which translated from Thai means “water passing through” - speaks about its essence.

Cave on the beach in New Zealand.

In most caves, the air is breathable due to natural circulation, although there are caves in which you can only be in gas masks. For example, guano deposits can poison the air. However, in the vast majority of natural caves, air exchange with the surface is quite intense.

In addition to caves that have access to the surface and are accessible to direct study by humans, earth's crust there are closed underground cavities. The deepest underground cavity (2952 meters) was discovered by drilling on the coast of Cuba

And this is just a cave and beautiful lake. Unfortunately, the photographer forgot to leave the name of the area.

Castor cave Olsztyn in Poland. Caves according to their origin can be divided into five groups: tectonic, erosion, glacial, volcanic and, finally, the largest group - karst. Most of these caves are like this. It is karst caves that have the greatest extent and depth. Karst caves are formed due to the dissolution of rocks by water, so they are found only where soluble rocks occur: limestone, marble, dolomite, chalk, as well as gypsum and salt.

Reed Flute Cave in China. This is an iconic place in Guilin, China, located in a picturesque area with karst formations. This natural limestone cave gets its name from the reeds that grow around it, which the locals used to make ancient wind instruments.

Caves appear in many fantasy works (both fantasy and science fiction). Caves (more precisely, bunkers) in science fiction mainly serve as shelters after a global catastrophe that has made life on the surface impossible. In fantasy, caves are inhabited by gnomes, kobolds, goblins, dragons; V role playing games they often play the role of dungeons. In Russians folk tales among the inhabitants of the caves are the Mistress of the Copper Mountain and the Serpent Gorynych.

Ice Cave at Matthiessen State Park, Illinois.

Krubera-Voronya is the deepest (at the beginning of 2014) cave in the world (depth 2196 meters), located in the Arabica mountain range in Abkhazia. The entrance to the cave is located at an altitude of about 2250 m above sea level in the Orto-Balagan tract. A karst cave of a subvertical type is a series of wells connected by climbers and galleries. The deepest plumbs: 115, 110, 152 m:

Among the most famous literary heroes who ended up in the caves: Tom Sawyer along with Becky Thatcher, as well as Bilbo Baggins.

Cave of Crystals, Iceland. You can enter the cave from the shore, through a 7-meter hole. The tunnel gradually narrows, and at the end its height is no more than 1.2 meters. Ice caves are generally unstable and can collapse at any time. They are only safe to visit in winter, when cold temperatures cause the ice to freeze heavily. Cracking sounds are constantly heard in the cave. They are heard not because the cave is about to collapse, but because the cave is moving along with the glacier itself. Every time the glacier moves a millimeter, loud sounds are heard.

Prehistoric people used caves all over the world as homes. Even more often, animals settled in caves. Many animals died in trap caves starting from vertical wells.

The longest cave in the world is Mammoth Cave (USA) - karst, built in limestone. It has a total length of passages of more than 600 km. The length of the explored part of the cave system is more than 587 km. In the surveyed part there are 225 underground passages, about 20 large halls and more than 20 deep shafts:

The extremely slow evolution of caves, their constant climate, and protection from the outside world have preserved a huge number of archaeological finds to us. This is pollen from fossil plants, bones of long-extinct animals (cave bear, cave hyena, mammoth, woolly rhinoceros), rock paintings of ancient people.

Although the living world of caves, as a rule, is not very rich (excluding the entrance part where sunlight reaches), nevertheless, some animals live in caves or even only in caves. First of all, this bats, many of their species use caves as daily shelter or for wintering. Moreover, bats sometimes fly into very remote and hard-to-reach corners, perfectly navigating the narrow labyrinthine passages.

(Photo by Danny Xeero) The Batu Caves were created by nature more than 400 million years ago. IN XIX century one merchant from India built a temple to the god Muruga in this secluded place.

The cave is naturally a natural cavity that has arisen in a mountain, large enough for a person to penetrate. They are studied by such a science as speleology. Thanks to speleologists, we know a lot about caves, because they can be very different: deep, beautiful, bizarre or simply huge. What is the deepest cave in the world and what other outstanding caves exist on Earth?

This Vietnamese cave was discovered relatively recently - in 1991 - by a local resident who was afraid to enter it because of the terrible roar of water inside and called friends for help. Eighteen years later, speleologists from Britain began to study it closely. Having covered a distance of four kilometers, they came across an obstacle in the form of an impressive wall, entirely formed from solid calcite (rock-forming material). In 2010, the study resumed again, the expedition stayed in the depths of the cave for two weeks.

Unusual stone columns and deep gorges were found in the cave. The wonders of Shondong amazed the entire speleological world. The dimensions of the cave are truly gigantic; in some places a skyscraper could fit there. It resembles a lost city underground. It’s even surprising that for so many years no one suspected its existence.

When floods occur, it is not possible to enter the cave

The cavity is 150 m high and about 9 km long. After the opening of the cave, extreme sports fans flocked there. To get underground, you will need a rope and other climbing equipment. Along the way, you will be able to explore dark labyrinths decorated with real rock patterns created by water flows. After all, inside this strange cave a stormy underground river roars, creating various tunnels. In some places she managed to break through to the surface.

Shondong is an extremely unusual place. 70-meter stalagmites grow here, attracting the attention of tourists, and real clouds are formed due to the mixing of warm and cold air. No matter how difficult and tiring the path to the cave may be, everyone who has been there unanimously assures that it is worth it.

Lubang Nasib Bagus

This largest cave in the world is located in Malaysia. It has a famous grotto called Sarawak. This grotto has very impressive dimensions - 600 by 415 m, and a height of about a hundred meters. The total volume of the grotto reaches a fantastic figure of 25 million cubic meters. It was discovered by three cavers from England in 1981.

At that time, they examined the karst massif, which is located in the Gunung Mulu Nature Reserve. The scientists climbed up the river and found themselves in the cave from which it flows. The speleologists didn't even have enough flashlights to fully illuminate it.

The area occupied by the Sarawak Grotto can easily accommodate several dozen aircraft.

Miao (Miao)

China also has one of the largest caves on the planet. It is hidden under the hills, and you can only get there by moving along underground river. The cavity is a huge cave chamber. Several years ago, an expedition took place to study this chamber in detail using the laser method.

This expedition was organized by the British, including specialists from the Chinese Institute of Karst Geology. Funding was provided by the American National geographical society. Later, all the information was announced at a conference on the issue of caves held in England. After extensive laser scans, the cave was officially mapped in 2013.

The volume of Miao is approximately 11 million cubic meters

Eisreisenwelt

Is on the planet amazing place, surrounded on all sides by ice. It is located in Austria near the city of Salzburg. This is the longest cave in the world that is partially made of ice.

The cave goes as much as 40 kilometers into the depths of the Alpine mountains, but ice occupies only a small part of it, followed by limestone. The cave was formed by the efforts of the Salzak River, which made a hole in the mountain, and the ice appeared due to snow that fell into the cave and into winter period were freezing.

The entrance to the ice part of the cave is always open to tourists, and cold winds constantly blow through the tunnels, which prevents snow and ice from melting, and in the warm season, cold air rushes out, forming a kind of air jam.

According to official data, the discoverer of the cave was A. Posselt in 1879. This naturalist, however, was able to explore only the initial 200 m. Before the discovery, only local residents knew the cave. They were afraid of it, calling it the devil's abode. In the mid-20th century, it was decided to build a special cable car, which reduced travel time from 1.5 hours to just 3 minutes. The open season lasts from early May to late October. A full tour of this impressive site will take approximately 1.5 hours.

It's difficult to find a photo of the cave's interior because photography is prohibited there.

Red Cave

On the Crimean Peninsula, part of Russia, there is also an outstanding cave, or rather a cave system, stretching for more than 25 kilometers. There are many halls underground different sizes And appearance, between them lies a difficult labyrinth. True, only 500 m is accessible to tourists, and then under the supervision of an experienced guide.

Internal view The cavity is striking primarily due to the lighting, skillfully distributed along the entire route. Its intensity is adjusted in such a way that the relief is emphasized and beautiful shadows are created. Walking through the cave is convenient and safe: it is equipped with special paths with railings. The place is very interesting from the point of view of speleology, especially for its large stalagmites and bizarre sagging on the walls. There is also an amazingly clean river flowing inside. It is so transparent that sometimes it can only be seen by reflections of light.

Hearing this name, anyone will imagine the remains of the greatest prehistoric giants discovered by scientists underground. But this is just a play on words, in the English dialect “mammoth” means huge. However, despite the fact that it has nothing to do with mammoths, traveling in it is extremely exciting. This is a whole underground kingdom, full of halls, galleries and passages. The cave seems to live its own, independent life: rivers roar here and waterfalls bubble. The reservoirs even have their own unique fauna: blind fish, shrimp without eyes...

The main entrance is located in the USA, Kentucky. Nearby, in the western part of the Appalachians, there are several smaller underground systems that were previously considered independent, but now it turns out that they are all somehow connected to Mammoth. A significant national park was founded on this territory, where a colony of rare bats lives and you can enjoy untouched nature. In Mammoth Cave, scientists have repeatedly come across unusual finds, for example, the mummified corpse of an Indian, perfectly preserved along with clothes thanks to special climatic conditions.

The cave has not yet been fully explored, but its estimated length is 587 km.

Sak-Actun

This unique cave is one of the main attractions not only of Mexico, but also of the world. Flowing in it large river has the same name, translated meaning “white cave”. The cave system has a length of more than 300 km and is a suite of rooms connected by passages. The study of Sac Actun, located on the Yucatan Peninsula, began only in 1987, but in the years since then, only one percent of the territory has been studied. It is difficult to imagine how many more amazing things are hidden in it, because the cavity was formed 65 million years ago.

According to one version, its occurrence is the result of a collision of the Earth with a huge meteor. At the place where it fell, a crater appeared, from which, in turn, many cracks spread underground. Time passed, and the crater, along with the cracks, was filled with rainwater. And so it turned out to be a long deep underground channel. Local tribes, such as the Mayans, have always treated this river with respect.

The river occupies almost the entire cave, and the spectacle is extremely beautiful.

Krubera-Voronya

This cave is located in Abkhazia. Its length is just over two kilometers, and Georgian scientists began to study it in 1960. Krubera-Voronya is of interest not only for speleologists, but also for biologists. Here they discovered a previously unknown species of beetles, which were recognized as record holders among insects for the depth of their habitat. Biologists also claim that many other new species can be found in this place.

The cave is mainly studied by the famous speleological group Cavex. It was this team that was the first to reach the maximum depth - 1.7 km. Research cannot be called easy: the expedition kept coming across dead ends and had to go back. It also happened the other way around: windows were discovered in the wall of the cave, leading to the opening of new paths.

From Kruber-Voronya flows the most short river on the planet - Reprua, which is only 18 meters long

Sarma

Sarma is located in Arabica Mountain in Georgia. It is a series of wells and halls, between which many tunnels and small climbs meander. Sarma is unanimously recognized by scientists as one of the most beautiful and scientifically interesting caves, extremely valuable for the world speleological community.

Sarma is conventionally divided into three levels - the first goes to a depth of 420 m, the second - to 900 m, the third - to 1830 m, further the territory has not yet been explored. Sarma received its name in accordance with the name of the wind: due to the peculiarities of aerodynamics, a strong wind always blows here hurricane wind, reaching speeds of 50 km/h, which local residents are afraid of.

The cave is closed to tourists, so you can get into it only as part of an expedition with the appropriate skills and equipment

Our Earth is a place filled with amazing wonders and mysteries of nature, only a small part of which has been explored by mankind. Huge and majestic caves always delight travelers.

Research of caves has been going on for years, expeditions find more and more natural formations. Some caves are considered beautiful, others are difficult to pass through, there are the most large caves.

The longest cave in Russia

There are many caves in Russia, both dry and flooded. The Botovskaya Cave is considered the longest. It is located near the village of Konoshalovo in the remote taiga Irkutsk region. To date, more than sixty-eight kilometers of underground passages have been explored, however for a long time it was believed that the length of this natural object was about seven kilometers.

She was discovered by chance by a local hunter following the scent of a bear. This cave has a grotto containing lakes. The uniqueness of the Botovskaya cave is that it consists not only of limestone, as is most often the case in karst caves, but also of sandstone. The type of this object is horizontal.

The cave was first explored in 1947. It has about twelve thousand intersections and many intricate passages. In 2013, an expedition discovered a map of this cave carved into stone, which exactly repeats the passages. The size of this “map” is relatively large.

While studying the passages, it became clear that the Botovskaya cave was visited more than once by Neolithic researchers.

The opportunity to get into the cave appears only in winter, since it can only be reached by tractor on the ice of the Lena River. The path on the ice is almost ninety kilometers.

But the Orda Cave is recognized as the longest underwater cave in Russia. It is located in the Perm region, eighty kilometers from the city of Kungur and received its name in honor of the nearby village of Orda. It was discovered when the high left bank of the Kungur River collapsed.

Scientists first explored the cave in 1993. It is a plaster horizontal labyrinth. Most of it is filled with water. The length of the cave is four kilometers six hundred meters. Being the largest water cave in Russia, it is in second position in Eurasia.

Large and beautiful caves

Since there are many caves in the world, we can highlight several of the most beautiful and largest ones. Such is the caves of Zakynthos, located on the Greek island of the same name. The caves reflect the color of the sky and ocean. They are also called blue caves. The Cave of Melessani, or as it is also called, the Cave of the Nymphs, is also located in Greece.

In the southwestern part of Slovenia there are the staggeringly sized Škocjan caves. The underground halls and gorges are immense in shape. In fact, this is a whole network consisting of eleven caves.

In Chile Chico there are the most beautiful Marble Caves. The amazing thing is that they are entirely made of marble. The beauty of the naturally formed caves mesmerizes visitors who come there.

In America there is National Park with the name "Mammoth Cave". The park was founded in 1941 and is located in Central Kentucky. The cave system is recognized as the longest in the world.

It is impossible not to say about the caves of Cenota Yucatan. They formed on the Yucatan Peninsula. Even the Mayan Indians considered them sacred.

In 2000, the Crystal Cave was discovered in Mexico. Its second name is the Cave of Crystals. It contains many huge selenite crystals. You can visit the cave only with special equipment, since it is located at a depth of three hundred meters, and with a humidity of ninety-nine percent, the air temperature there reaches fifty-eight degrees.

The most amazing and unique is the Romanian cave Movile. Its uniqueness is that it is a closed ecosystem. For five million years it existed separately from the Earth's ecosystem. This was the reason that several dozen unknown plants and living creatures were discovered in this cave. It was opened only in 1996.

On the island of Borneo there is Ila National Park. There is a cave there, discovered in 1980, reaching a kilometer in length, two kilometers in width, and its height is two hundred meters.

There is a cave in the US state of New Mexico large sizes– Big Room or “Big Room”. Its length is five hundred and fifty meters and its height is seventy-seven meters.

The largest cave in Vietnam

It is in Vietnam that there is a cave that is recognized as both the largest and most beautiful in the world. Its name is Hang Son Doong or Son Doong Cave. The location of this natural site is Quang Binh province, five hundred kilometers from Hanoi, near the border with Laos in national park Phong Nha-Kebang.

Local residents have known this huge cave since 1991, and it was discovered by speleologists in 2009. It was not easy to find her, since she is located in impenetrable jungle. Its width is one hundred meters. The length of Shondong has been studied for six and a half kilometers, while in some places the height reaches two hundred and forty meters.

The deepest cave in the world

Among all the caves in the world, the deepest is the Crow Cave or Krubera Cave, located in Abkhazia in the Gagra ridge. The cave is branched, there are two branches in it. The depth of one is one kilometer three hundred meters, the other is two kilometers one hundred and ninety-six meters.

The cave was discovered and explored for the first time in 1960. The last expedition dived in 2012. Each subsequent expedition tries to reach greater depths than the previous one.

The caves surprise not only with their size, but also with their beauty. But there are other beautiful places in Russia. .
