Nature #05: The Underworld


Well, here we go on another one of our trips, through a world that is real, but that very few know or even heard of: it is the mysterious "Cave World", not just one or two, several of them even in unsuspected places. They enchant, not only for their greatness, but also for their beauty. Check out the new #Nature in full! 🙂

We can find them in the most remote places of our immense world: in Asia, North America and Europe. Some of these caves are formed when the water seeps down through cracks in the limestone rock. The limestone rocks dissolve little by little, forming openings.


For millions of years, these openings, and the limestone left by the drops of water, have managed to form majestic caves, like some of them that readers will see in photos posted in this article. However, some despite taking millions of years to form, they have been eroded by the water of lakes or the sea.

However, if you are thinking of visiting them, beforehand I advise you to curb your curiosity, because, although they are open to visitation, such as: Phraya Nakhon, in Thailand, most of them have their visitation only released, for radical adventurers who must obtain passes in advance.

As you can see in the images that we publish, people who get the opportunity to explore these wonders of nature, carry several special equipment. The good news for us poor mortals is that in almost all expeditions, those who have the privilege of visiting them, are accompanied by professional photographers.

The photo sessions, of the highest quality and resolution, give us the opportunity to learn about these mysterious places, a gift from Nature, many of them practically untouched by humanity (literally). Here we go? 😉

1 - Son Doong Cave, Vietnam

It is the largest known cave in the world today. It is full of countless beauties, including isolated ecosystems, climatic systems and geological formations. Its dimensions are impressive, at least 4.5 kilometers long, reaching 140 meters high in some parts, perhaps for this reason, its end has not yet been found.


2 - Ice cave near the Mutnovsky volcano, Russia

Ice caves like this one form in the glaciers that surround the Mutnovsky volcano in Russia. Some of them are formed by openings that originate from volcanic cracks.

3 - Vatnajokull glacial cave, Iceland

It is located on the Vatnajokull glacier in Iceland, the largest glacier in Europe. These species of caves are formed as a result of the frozen water of the glacier. For this reason, they can be quite dangerous, because glaciers are constantly breaking down and changing their formation.

4 - Naica Mine, Mexico

These caves are home to some of the largest crystals ever found - the formations are magnificent, worthy of comic book heroes, such as Superman, because they reach up to 11 meters in length and 4 meters in diameter.

However, like everything in this life, there is a restriction, which in this case, has a very understandable reason: the Crystral Cave, where the crystals are located, visitation is closed because of its depth, heat and so many other reasons.


However, to everyone's delight, a large volume of images were taken to document the gigantic crystal cave.

5 - Batu Caves, Malaysia

The caves now mentioned, have been used by Chinese and English settlers, as well as by the indigenous Temuan people. The excrement of cave bats was extracted for use in agriculture, but nowadays, the place is occupied by gigantic statues. The good news is that this beauty is open for visitation.

6 - Mendenhall ice caves in the United States

This ice cave is part of the Mendenhall Glacier, near Juneau, Alaska's capital. The magnificent work was sculpted in the melting glacier and, the incidence of sunlight, is what gives rise to a fabulous aspect in the place. Due to the conditions of constant changes in the glaciers, we cannot say whether this cave will survive long.

7 - Cave in Algarve, in Portugal

This cave is located in a place prone to several formations by the sea, due to the relative solubility of the rocks in the water. In this specific case, this cave, near Lagos, can only be accessed by water.

8 - Glow Worms Caves, New Zealand

Waitomo's Glow Worms caves are home to a unique insect due to its peculiarities - the luminous Arachnocampa firefly. It produces shiny threads of silk that descend down the cave ceiling and shine to attract innocent prey.

The set of the dark cave, with thousands of luminous points, gives the place an aspect of the night sky, as if it were the "copy" of an anonymous painter, of the work created by the Supreme Architect of the Universe. They can be visited with a guide.

9 - Tham Lod Cave, Thailand

It is what we can call a cave covered with mysteries, because very little is known about this cave in Kyaut Sae, in Myanmar. What is only known is that inside it, a “work” was made, making it resemble a Buddhist temple. The view from inside is magical.

11 - Marble caves in Patagonia

Patagonia's Marble caves are known for their stunning reflections that turquoise water casts over the cave's white marble ceiling. These are also called “Marble Cathedral”, due to its beautiful shapes and characteristic arching.

12 - Antelope Canyon, in the United States of America

Located in Arizona, it has been sculpted by thousands of years of wind and floods of recurring lightning, which make its smooth walls look very smooth and fluid to our eyes.

During the desert monsoon season, floods can occur that become dangerous because they cannot be predicted. Such floods, unfortunately, ended up causing the death of some unsuspecting tourists.

13 - Phraya Nakhon Cave, Thailand

The cave mentioned above was historically a popular place visited by the local kings, due to the lighting provided by its roofs, which eventually collapsed. The pavilion, in the center, was built especially in order to receive the visit of King Chulalongkorn, in the year 1890. It is an extraordinary work.

14 - Ellison's Cave, in the United States

In this cave there is a moat from the Fantastic Cave, which is part of the Elisson Cave, in the North American state of Georgia. It is a very popular attraction among so-called “Pit climbers”, who are adventurous and are admittedly fans of rappelling in vertical underground falls, for those who like adrenaline, there should be no better feeling than practicing this type of "sport".

15 - Orda, Russia

Ordinskaya, or Cave Orda, is the longest underwater cave in Russia and the only one of its kind made of plaster, with no other in the world. Its length is almost 5 kilometers of water so crystal clear, that divers can see about 45 meters in front of them. Another characteristic of this cave is the absence of currents.

Now, be careful: this is not a place for anyone to get lost, for the simple reason that there are smaller passages that can take people away from the main cave and are not yet very easy to recognize.

The water in this cave has a temperature capable of freezing, since it is minus 20 degrees Celsius on the surface, and anything that someone touches it risks breaking very easily. The diver Lamar Hires, reports that he saw pieces of plaster as big as cars and buses falling from the walls and ceiling of the cave.

We ended our great adventure here ... Until next time! 😉
