Part
of the US National Park in central Kentucky, the Mammoth Cave has the
longest cave system in the world called the Mammoth-Flint Ridge Cave
System with over 365 miles of subterranean passageways. Established as a
national park on July 1, 1941, it also became a UNESCO World Heritage
Site (1981) and an International Biosphere Reserve (1990). Other
spectacular sights to see include the giant sinkhole aptly named ‘Cedar
Sink,’ and the ‘Frozen Niagara.’



The
Phong Nha Cave, which is a part of the UNESCO World Heritage Site in
Phong Nha-Ke Bang National Park, is located in the Minh Hoa districts in
north-central Vietnam, about 500 km south of Hanoi. The national park
was created to protect its over 300 caves and grottoes, aside from the
ecosystem and the limestone forest of the Annamite Range. Out of the 300
Phong Nha caves, only 20 of those have been surveyed by scientists.
With a total length of 126 km, it held several records including the
longest underground river and the largest caverns and passageways before
the discovery of Son Doong Cave.

A
natural cave in Belize near San Ignacio in the district Cayo, it is not
only a popular tourist destination but an archaeological site as well. A
single-passageway resurging stream with 6,400 meters of passages, there
is an indication that there can be an additional 6 km of passageways as
shown by the dry traces at sinking streams. An important archaeological
site, there was evidence that the first kilometer of the cave
passageway was used by Mayans due to a number of pottery shards that
have been discovered dating as far back 200 AD along with the remains of
28 humans.

A
protected cave system in Slovenia, the cave is just 2 miles long but
attracts year-round tourists and visitors. It consists of the Reka
River, which goes underground for an additional 21 miles and represents
one of the longest ‘karst’ underground wetlands in Europe. It became a
UNESCO World Heritage Site in 1986 and was lauded by the scientific
community as one of Earth’s natural treasures.


This
cave in Leasburg belongs to Missouri National Park, which was
established in 1982. Although it was first settled by people in the
1850s, it has a history of land disputes and vandalism. It is now
secured as a protected national park where cave tours, swimming,
fishing, picnicking and hiking are being offered at the visitor’s
center, which also has a nature museum. The Onondaga Cave boasts of
towering stalagmite, dripping stalactites and other active flowstones.

A
national park since 1971, the Puerto Princesa Subterranean River
National Park is located in Palawan, Philippines. Also known as the St.
Paul Underground River, it is a part of the Saint Paul Mountain Range.
Aside from the underground river where visitors can explore the cave in a
boat, it was also discovered in 2010 that the underground river has a
second floor, indicating the presence of small waterfalls inside the
cave. It is composed of a huge 300-m cave dome; unbelievable rock
formations, and an underground river.

This
cave is located in the Selma Plateau, 1,380 m above sea level in the
Sultanate of Oman. Formed in fossilliferous carbonate rocks, it is the
9th largest cave chamber in the world. A single chamber alone measures
about 310 m by 225 m with a free-standing roof about 40 m thick. The
cave has a volume of 4,000,000 cubic meters, while its floor area is
about 58,000 square meters. Its deepest part is about 178 m below the
top of the highest entrance.



A
landmark and a tourist attraction outside the city of Gullin in
Guangxi, China, its name was derived from the reeds growing inside the
cave that are ideal for flute making. It offers magnificent rock and
mineral formations, stone pillars, and carbon deposits. Illuminated by
different colored lights, it has been one of Gulin’s most interesting
tourists’ attractions for the past 1,200 years. Rediscovered in 1940s by
a group of refugees, this 180 years old cave has more than 70
inscriptions written in ink that date as far as 792 AD to the Tang
Dynasty.

A
famous sea cave on the coast of the island of Capri in Italy, the
sunlight that passes through the underwater cavity and shines through
the seawater creates a blue reflection that illuminates the cave.

The
Kverkfjöll ice cave, located in a frozen lagoon in Skattafel, Iceland,
is considered one of the most famous glacier caves in the world. Formed
by the hot water from a volcanic spring below Vatnajökull glacier, it
was discovered during an expedition in the 1980s.

The
location of some complex caves in southwestern France, it is more
famous for its Paleolithic cave paintings, which were discovered by a
teenager in the 1940s. The Paleolithic art, which is estimated to be
17,300 years old consists of images of large animals known to exist in
the area due to fossil evidence. Listed as a UNESCO World Heritage Site
in 1979, it was opened in 1948 but was closed down to the public until
1963 to preserve the art. The rooms in the cave that you can explore
include the Chamber of Felines, the Hall of the Bulls, the Apse, the
Nave, the Shaft, and the Passageway.

This
was just recently discovered in 2000 when scientists discovered the
chasm below after drilling an aquifer and pumping out tens of thousands
of gallons of water. A cave that is connected to the Naica Mine in
Chihuahua, Mexico, its crystal formations are mind bogglingly large and
measure over 30 feet in height and 4 feet in diameter. Formed due to the
water-source that is rich in calcium sulphate, it was heated by an
infusion of magma making the cave extremely hot and people can only
endure ten minutes of exposure with proper protection. This is also the
reason why most parts of the cave are unexplored.

A
cave at Waitomo on the north island of New Zealand, it is known for the
population of glowworms that are around the size of an average
mosquito. It is part of the Waitomo Cave system along with the Ruakuri
Cave and the Aranui Cave. Unique only to New Zealand, this is a must-see
for any traveler who can enjoy a boat ride amidst thousands of
glowworms illuminating the cave and be a part of over 120 years of
cultural and natural history.

A
sea cave on the uninhabited island of Staffa in Scotland, it was formed
entirely from hexagonally-jointed basalt columns within a Paleocene
lava flow. It is well-known for its naturally arched roof, which
produces eerie sounds made by the echoes of the waves to give the
atmosphere of a natural cathedral.

An
open airpit cave situated at the Municipality of Aquismon in Mexico, it
has freefall drop of 333 m from the floor of the cave to the lowest
side of the opening, with 370 m drop from the highest side. The 2nd
deepest pit in Mexico and the 11th in the world, a skyscraper like the
NYC Chrysler Building could easily fit. The cave has low temperatures
with thick vegetation at the mouth and rains can cause waterfalls to
cascade into its opening. Aside from the layers of debris and guano, you
can also find a sinkhole in a fault of the lower Cretaceous limestone,
which can go down further to 512 m.

Also
known as ‘La Cueva del Fantasma,’ this is an interesting cave located
in southern Venezuela. Situated in one of the most biologically rich and
geologically ancient parts of the world in the Aprada tepui, it is just
barely large enough to contain two helicopters. However, experts
believed that this is not actually a cave but a collapsed steep gorge.
