The Jeita upper cave has an overall length of 2,130 meters (7,000 ft) of which only 750 meters (2,500 ft) are accessible to visitors via a specially conceived walkway; access to the remainder of the cave was restricted to prevent ecological damage which may occur due to the flocking tourists. The upper cave contains a great concentration of a variety of crystallized formations such as stalactites, stalagmites, columns, mushrooms, ponds, curtains and draperies. The longest stalactite in the world is located in Jeita’s White Chamber; it measures 8.2 meters (27 ft) long. The upper cave houses the world’s largest stalactite and is made of a series of chambers the largest of which has a maximum height of 120 meters (390 ft).

The cave contains many large stalactites and stalagmites many of exceptional beauty. A feature of the stalagmites is their “dish-pile” appearance, formed by water dropping from up to 80 meters above and depositing calcium carbonate over a wide area.

Although the extensive system of tunnels and chambers go on for over four kilometers, only about a quarter of this is open to visitors, who may proceed into the cave only in groups supervised by a guide. Tours are conducted at regular intervals on most days – there is a “Standard Tour” which takes an hour and an “Adventure Tour” which takes an hour and a half. The “Adventure Tour” consists of crawling through narrow passages and climbing up steep rock formations guided by small lights. The caves contain spectacular halls and grand limestone formations (on both tours) as well as some rather small passages on the Adventure Tour. The smallest passage that tourists will have to pass through on the Adventure Tour is just under 30 cm high at the exit.

In 2004 the penetrated depth was increased on each of three expeditions. At that point the Ukrainian team crossed the -2000 m mark for the first time in the history of Speleology. In September 2007, a new, unexplored part was found by Alexandre Klimchouk, and the cave became even deeper. This expedition confirmed the depth of the cave which is now 2,191 (±9) meters deep.

The largest of the chambers, named the “Cathedral Cave”, currently serves as an auditorium. It was converted due to the chamber’s natural acoustic properties, which according to experts, enhances and blends tones into a uniform and faithful rendition of sound. It is equipped with a concrete stage and has a seating capacity of over 100. St. Michael’s Cave can be reached by car, taxi, cable car or by foot.

The Cave Bath is a thermal bath in a natural cave in Hungary and is unique in Europe. The thermal water (temperature: 30°C, 86°F) is reputed to cure pain in the joints, and since it has lower salt content than most thermal waters (around 1000 mg/liter), people can bathe in it for much longer, practically for an unlimited amount of time. The Cave Bath can be visited all year long except for January.

13. Víðgelmir: Lava Tube Cave

Image Source

Víðgelmir is one of the longest (1.585 m) caves in Iceland and largest (148.000 m³) lava tube cave in the world. It’s situated in Western Iceland. The roof of the lava tube has collapsed, creating two large openings near its north end which are the only known entrances. The cave entrance is wide but narrows down in some places. An iron gate was installed at the first constriction in 1994 to preserve the delicate lava formations or speleothems which haven’t already been destroyed. Evidence of human habitation, probably dating to the Viking age, has been discovered in the cave and is preserved in the National Museum of Iceland. Long stretches of the cave floor are very rough and shouldn’t be navigated without a guide.

Lava tube caves are formed when a low-viscosity lava flow develops a continuous and hard crust which thickens and forms a roof above the molten lava stream. When the eruption subsides, the still molten lava moving beneath the crust will continue to drain downhill, leaving an open lava tube cave.

14. Marble Arch Caves: Limestone Cave

The Marble Arch Caves are a series of natural, limestone caves located in Northern Ireland. The Marble Arch Caves are a popular tourist attraction due to their accessibility and grandeur. The caves were opened to the public in 1985 following work to make them more accessible the previous year. Tourists can partake in a seventy-five minute long tour of the show caves during which they travel through the first part of the caves in a specially designed boat floating on the subterranean Cladagh River, before walking through the rest of the chambers.

15. Blue Grotto: Sea Cave

The Blue Grotto (Grotta Azzurra) is a noted sea cave on the coast of the island of Capri, Italy. Sunlight, passing through an underwater cavity and shining through the seawater, creates a blue reflection that illuminates the cavern.

Image Source

The Blue Grotto has become the emblem of the island of Capri. The grotto was known by the Romans, as proved by the antique statues which were found in the Grotto. This discovery, the remains of an ancient landing place and the work on an underground tunnel, create an image of a natural cavern adorned by statues. The grotto was known to the locals under the name of Gradola, after the nearby landing place of Gradola, but it was avoided because it was said to be inhabited by witches and monsters. The Blue Grotto was used by the emperor Tiberius as his private swimming pool.

Holloch Cave is a 194km long cave situated between the river Muota and the area of the Pragelpass in the Valley of Muotha in Switzerland. It is also notable for having a depth of 939m. The initial exploration started in 1875 and was led by Alois Ulrich. A large part of the exploration of this cave was led by Alfred Bogli. The explored length of the cave increased from 25km in 1952 to 100km in 1968 (it was the first cave in the world where the explored length reached 100km.) Until 1970, it was thought to be the largest cave complex in the world, this title now thought to be held by Mammoth Cave National Park.

17. Optimisticeskaja: Gypsum Cave

Optimisticeskaja, meaning “optimistic” in Ukrainian, is a gypsum cave in Ukraine. As of 2005, it has 230 km of mapped passageways. By some other sources it is referred as having about 133 miles (214 kilometers) of surveyed passageways, that makes it the third-longest cave in the world, after Mammoth Cave and Jewel Cave) and the longest gypsum cave in the world. The entire cave lies under a 2-kilometer square area in a layer of Upper Tertiary gypsum that is less than 20 meters thick. The passages tend to be low and often choked with mud. They comprise a dense network on several levels, making Optimisticeskaja what is known as a “maze cave.”

18. Dobsinska Ice Cave: Ice Cave

Dobsinska Ice Cave is an ice cave in Slovakia. It is included in the UNESCO World Heritage list as a part of Caves of Aggtelek Karst and Slovak Karst site. It lies 130 m above the Hnilec River, and the entrance is at an altitude of 970 m. The cave was discovered in was open to the public just one year after its discovery. And in 1887, it was the first electrically lit cave in Europe. The cave slowly descends from the entrance and with the northern orientation it cools off cave’s interior in winter, as the cold air falls down. In the summer, the warm air cannot fall down to the cave. Thus the annual temperature average stays around 0°C. The cave iced up, as this cycle repeated for many centuries.
