The Door to Hell
The flaming hole is located in central Asia in the state of Turkmenistan. It is located in the Karakum desert near the village of Derweza, about 260 kilometers from the capital of Ashgabat.
It is believed that the capacity of natural gas found in the hole is one of the largest in the world. The name “Door to Hell” has got holes because it burns since 1971 when the site was found. The hole diameter is about 70 meters, while the depth is about 20 meters.
In an effort to minimize the risks of gas, they were set on fire by expecting it to burn in a few days. But the budgets seem to be far away, and the crater continuously burns for 45 years. A large part of Turkmenistan is rich in natural gas and there is little understanding of how long it will continue to burn.
Travertine Pools of Pamukkale
Pamukkale is a natural site in Denizli in southwestern Turkey. The area is famous for a carbonate mineral left by the flowing water. It is located in Turkey’s Inner Aegean region, in the River Menderes valley, which has a temperate climate for most of the year.
Tourism has been a major industry in the area for thousands of years, due to the attraction of the thermal pools.
Overshadowed by natural wonder, Pamukkale’s well-preserved Roman ruins and museum have been remarkably underestimated and unadvertised; tourist brochures over the past 20 years have mainly featured photos of people bathing in the calcium pools. Aside from a small footpath running up the mountain face, the terraces are all currently off-limits.
The Initiation Wells
Located near the historic center of Sintra, Portugal lies a spectacular estate that sits in a World Heritage protected landscape.
Along with the other palaces it is considered one of the principal tourist attractions of Sintra.
The property consists of a romantic palace and chapel, and a luxurious park that features lakes, grottoes, wells, benches, fountains, and a vast array of exquisite constructions. The palace is also known as “The Palace of Monteiro the Millionaire”, which is based on the nickname of its best known former owner, António Augusto Carvalho Monteiro.
The wells were never used, nor intended for water collection. Instead, these mysterious underground towers were used for secretive initiation rites.
Caño Cristales – Colombia
Caño Cristales is a Colombian river located in the Serrania de la Macarena province of Meta. The river is commonly called the “River of Five Colors” or the “Liquid Rainbow,” and is even referred to as the most beautiful river in the world due to its striking colors.
A bed of rocks covered in dull green mosses are visible below a cool, clear current.
The river from the end of July through November is variously colored yellow, green, blue, black, and especially red, the last caused by Macarenia clavigera plants (family Podostemaceae) on the bottom of the river.
This only happens for a brief period in between seasons. During Colombia’s wet season, the water flows too fast and deep, obscuring the bottom of the river and denying the Macarenia clavigera the sun that it needs to turn red. During the dry season there is not enough water to support the dazzling array of life in the river. But for a few weeks from September through November, the river transforms into a veritable living rainbow.
The Catacombs of Paris
The Catacombs of Paris are underground ossuaries in Paris, France, the popular site houses the skeletal remains of some 6 to 7 million former Parisians, though not all areas of the Catacombs are open to the public. This ossuary was created as part of the effort to eliminate the city’s overflowing cemeteries.
Back in the late 18th century, cemeteries were becoming over-populated.
Preparation work began not long after a 1774 series of gruesome Saint Innocents-cemetery-quarter basement wall collapses added a sense of urgency to the cemetery-eliminating measure.
The ossuary remained largely forgotten until it became a novelty-place for concerts and other private events in the early 19th century.
Quarry tunnels have existed on the outskirts of Paris since Roman times. The limestone in these quarries built Paris as we know it today, and eventually, helped the city expand to the point where the quarries were directly underneath the busy metropolis. Some 200 miles of labyrinthine tunnels are believed to exist.
Despite the vast length of the tunneled, underground world, only a small section of it is open to the public. This tiny portion, known as Denfert-Rochereau Ossuary, or more popularly, “The Catacombs,” has become one of the top tourist attractions in Paris.
The Tunnel of Love – Ukraine
The Tunnel of Love located in Ukraine, Klevan, used to be just another train rail section, but eventually turned into one of the most romantic spots on Earth.It is a railway surrounded by green arches and is three to five kilometers in length. It is known for being a favorite place for couples to take walks.
As trees were left to grow freely around the rails, the passing train was the only thing shaping its way through. Eventually, by crossing the Kleven village forest back and forth three times a day, the train shaped a closed tunnel according to it’s size.
The tunnel is at its lushest during the spring and summer when the trees are at the peak of their leafiness, but the colorful foliage of fall and snow-covered branches of winter make for captivating sights as well.
The legend says that if two people are sincere in their love and cross the tunnel while holding each other’s hands, their wishes will come true.
The cenotes in Mexico
A cenote is a natural pit resulting from the collapse of limestone bedrock that exposes groundwater underneath,that leads to a pool of often gorgeous turquoise-colored water. Cenotes are common geological forms in low latitude regions, particularly on islands, coastlines, and platforms.
It was discovered almost 7,000 cenotes in Mexico’s Yucatán Peninsula.
Especially associated with the Yucatán Peninsula of Mexico, cenotes were sometimes used by the ancient Maya for sacrificial offerings.
Some cenotes are part of a massive underground network of rivers and caves that remain, for the large part, unexplored. Others are just afternoon swimming holes or cave-diving destinations.
Mount Buzludzha – Bulgaria
Buzludzha is a historical peak in the Central Balkan Mountains, Bulgaria. Formally known as the House-Monument of the Bulgarian Communist Party, the monument at Buzludzha Peak is like something out of a 1950s sci-fi movie. This building is 1432 meters high (4,698 feet).
In 1868 it was the place of the final battle between Bulgarian rebels led by Hadji Dimitar and Stefan Karadzha and forces of the Ottoman Empire.
The domestic monument of the Bulgarian Communist Party, along with 107 m towers, was designed by Georgi Stoilov.
Now abandoned, the site has become one of the world’s most famous modern ruins.
The lagoon can be found in the tiny fishing village of Las Coloradas, located on the eastern coast of Mexico’s Yucatán Peninsula. Las Coloradas has miles of pristine, empty beaches, making it an ideal private getaway. This rosy beach is part of the Rio Lagartos Biosphere Reserve, which protects nearly 150,000 acres of beaches, forests and dunes.
It’s SO pink that many people find it hard to believe it’s real. However, it’s completely natural, and there’s a perfect scientific explanation to it.
No magic or paint were used to color the lagoon. It’s actually inhabited by the red plankton and brine shrimp and they dye the water with their chemicals. The fairytale-like landscape is also decorated with the piles of salt as Las Coloradas was once a salt mining town.
This is not the only body of water on Earth to trade up for that coveted pink hue. Koyashskoye Salt Lake in Crimea alternates between pink and red because of its high concentration of microscopic algae and brine shrimp. Several lakes in Australia are pink for the same reason. But of all the pink paradises, Las Coloradas might be the prettiest.
