Unusual beaches. The most yellow beach. Red sand beaches

When we think about the sea coast, our imagination immediately reproduces a picture of a beach with golden sand washed by the waves of the azure sea. Could you imagine that the sand in this very picture is not golden, but... green? Or maybe black? Or it’s possible that it’s not sand at all. It seems to me that all the most interesting things in our world can be created by nature. Therefore, let's give free rein to our imagination and try to imagine ourselves on the most unusual beaches in the world. Moreover, we will consider them in order of increasing unusualness, so to speak. Perhaps some of you have already seen these beaches in person.

So, let's take a trip to the most unusual beaches in the world?

The yellowest beach

So, let's start with the yellow sand we are all familiar with. But, again, yellow is different from yellow. In the photo below you can see that almost orange is meant. The yellowest representative among the beaches in the world is Ramla il-Hamra Bay and San Blas Beach, which is located on the island of Malta. As you know, the color of sand depends on the type of rock from which it is formed. Typically, the golden color of sand is due to the predominance of silicon dioxide in the form of quartz (SiO2) mixed with iron. The more iron in the sand, the yellower it is.

The whitest beach

We are also familiar with sand of such a beautiful color. Many beaches are its owners. For example, the Thai Similan Islands are famous for their white sands. You could even say that many beaches in Thailand are famous for their white sands. Thus, Sammet Island near Pattaya also has magnificent white sand. The sand on the UNESCO-protected Hong Island near Phuket is also almost snow-white. The list of white beaches also includes the island of Poda, where crabs are found. Another beach, located near Sydney. This beach has the whitest sand in the world. He can even boast of a place in the Guinness Book of Records for this. The main advantage of white sand is its extraordinary beauty in photographs. In any sunlight there is a feeling of unreality. But it's worth remembering that White sand reflects the sun's rays more strongly. Therefore, the tan will be more active. The white color of the sand is again due to its chemical composition. The white color of sand is usually found in the tropics and means great content calcium carbonate (CaCO3) from limestone rocks, as well as from the hard organs of corals. The corals die and turn the sand white.

The most cave beach

Many beaches boast mountainous landscapes. However, the most striking in this category is PhangNga Beach in Thailand. The beach is protected by UNESCO for its unique composition of rocks and minerals. It is surrounded by steep cliffs. And not just rocks. Looking at them, it seems as if they melted in the sun, trying to drain from the sea, and then froze, forming bizarre shapes. The beach's rocks are a collection of unique natural minerals and limestone in red, grey, brown and orange colors. The rocks consist of countless caves of various shapes. If you walk here and look closely, you can see mineral inclusions that look like semi-precious stones.

The most squeaky beach

So what? - you say. All sand creaks. But I want to talk about the sand, when walking along it with your eyes closed, it seems as if you are walking in the snow. So, again, in Thailand, there is Karon Beach, which is located in Phuket. He is the owner of 8th place in the world according to the rating of the most best beaches. Perhaps also due to the unusual properties of sand. The color of the sand is divided by a visible line into light golden and yellow. When you step on the light sand at the entrance to the beach, it immediately seems that you have been deceived - it does not creak. But, as soon as you walk closer to the sea and step on the yellow sand, all doubts immediately evaporate. The sand begins to creak underfoot. Unusual sensations.

The most shell beach

Shells are sea creatures. They can be found on any beach, just in different quantities. So there are beaches that are completely covered with shells. For example, Shell Beach, Gustavia, on the Caribbean island of St. Barts is the most shell beach in the world. The result of this kind of metamorphosis may be a change in sea level. For example, at this place the seabed was previously inhabited by clusters of mollusks, and when the bottom was exposed, they left their shelters on the shore and fled to the sea. Strong currents, hurricanes and waves constantly replenish the supply of shells on the beach. Due to the fact that the shells on this beach are white, it seems that the beach is strewn with flower petals. Very beautiful, of course. But walking probably hurts. For this reason, shell collectors have a blast here.

The most crab beach

There is such a province in Thailand - Krabi. From the name it is clear that it is a favorite place for crabs. Walking, for example, along Klong Muang beach, you will notice that the sand has a strange consistency. It consists entirely of small but very even balls. These balls cover the surface of the beach in countless numbers and form patterns. Moreover, the patterns are so smooth and beautiful that it seems as if (I already said this somewhere) their origin is foreign and they were painted by aliens. But the artists are not aliens at all, but crabs like these. They roll the balls themselves, digging holes for themselves in the sand. As you can see closer, in the center of each drawing there is a small hole - the crab's home.

The glassiest beach

We know that the beach can be sandy or pebbly. However, there is a beach in California, Glass Beach, Fort Bragg, which is covered with glass pebbles. That is, instead of pebbles, he has multi-colored glass pebbles. The origin of this kind of material, however, is not natural. The fact is that in the 20th century there was a trash can here. When the landfill was closed, mountains of broken bottles were washed by waves and blown by the wind for many years. So, nature has made one of the most unusual beaches in the world out of a terrible garbage dump.

The oldest beach

This is the nickname given to the beach with organic remains in the UK. A seemingly ordinary beach is a nature reserve due to the presence of unusual ancient rocks and remains in its bins. Here you can find extraordinary shells imprinted into stones, huge imprints of shells on rocks, as well as the shells themselves, which clearly came to us from the past. It is known for certain that the remains of dinosaurs and ancient lizards were also found on the beach.

The pinkest sand

Sounds incredibly romantic. Yes, and it looks the same. Pink Sand Beaches on Bermuda boast pink-tinged sands. Of course, such beauties are recognized as one of the most romantic places for, for example, honeymoon. Of course, the sand on the beach is not bright pink. But in the sun it clearly glows pink. Especially when in contact with sea ​​waves. Pink sand- this is the result of foraminifera living in these waters - microscopic animals whose shell is pink. They live in water and attach to reefs and fish. But periodically strong waves throw them ashore, where they leave their shells.

The reddest beach

There is probably a less romantic, but no less mysterious red sand beach in Hawaii. Red Beach is somewhat isolated and has high waves, which matches the color scheme. And the sand here is red thanks to long-ago eruptions of the Cauqui volcano, which filled the sand with iron oxide (rust).

The blackest beach

Look at the photo first. No, this is not land. This is sand. Punalu'u Beach, south of Hilo on Hawaii's Big Island, has warm, completely black sand. And again, volcanic eruptions are to blame. Volcanic lava basalt has flowed into the Pacific Ocean for centuries during eruptions. The water boiled, and lava particles splashed out along with the steam, turning into sand. After a long time, the beach turned into this black coast. Another attraction of this beach are the turtles, which, after migrating, love to bask on the black sand. Residents take care of the turtles and provide each with a sign: “The turtle is resting after a long journey. Please don't interfere!

The greenest beach

For me personally, green sand is associated with something foreign. Maybe that's how it is? The beach, again in Hawaii - Papakolea Beach, is absolutely green. And it wasn’t aliens who made the beach sand green. He is completely of earthly origin. And here, as it turns out, the volcanoes did their best. Scientists, while studying the green beach, confirmed the presence of green peridot crystals in it.

The most rainbow beach

And, finally, a beach that combines almost all of the above colors - rainbow. This beach is located in California. Pfeiffer Beach Big Sur is like one big canvas, which depicts abstract stripes, fancy patterns, as if painted with paint. And all because the hills around the beach contain pomegranate, particles of which, along with sea ​​water and paint the sand in unusual shades, and they are constantly different.

These are truly the most unusual beaches. Perhaps someone, having looked at such an abundance of beaches, will want to add to their travel collection and see them with their own eyes.

Have a pleasant experience and new discoveries!

Places where everyone would like to be photographed.

All beaches are the same: sun loungers, turquoise water and golden sand. But there are places where everyone would like to be photographed. Below are the ten most interesting ones. The holiday season is in full swing!

Glass Beach

Glass Bay, Ussuri Bay, Vladivostok (Russia)

A garbage dump that spontaneously appeared on the coast led to the formation exotic place recreation. “Ermine” (that’s what the landfill was called) irritated the townspeople for a long time. In 2011, the area was finally closed and hidden under a concrete sarcophagus. But the sea came into play. Gradually, fragments of broken bottles, covered in water, began to be washed out onto the neighboring sea area. This is how it was formed Glass Cove— Steklyanukha, as the locals call it. 70% of the surface of this beach is covered with round multi-colored glass, shimmering so beautifully in the rays of the sun and the foam of the surf.

In 2002, a similar beach in California became part of the McCarriher National Park. Today the territory is protected by the authorities. This site is one of the most famous glass beaches in the world. Thousands of tourists visit the territory and strive to take home a souvenir. It got to the point that the authorities developed a program for the delivery of broken glass to preserve the area’s features. Will the same thing happen? seaside bay- We'll see.

Secret beach

The Marieta Archipelago includes many islands that have been included in the UNESCO list of most important islands since 2008. biosphere reserves. The reason was unique caves, tunnels and rich fauna. On one of the uninhabited islands there is a beach hidden from the eyes of the uninitiated.

As a result of military tests (at the beginning of the 20th century, the United States tested artillery here), an oval-shaped hole was formed on the surface of the island. Under the influence of erosion, a unique landscape was formed: a narrow strip of sand under the sun's rays and a small pond hidden under the arches of the cave. The diameter of the cave is several tens of meters. Interesting marine animals enter the lagoon, making the beach especially attractive to tourists. The island is home to the largest population of sea swallows. It is home to 103 of the 159 recorded species of marine fish in Banderas Bay. Coral reefs of many varieties make the bottom topography interesting for diving.

Underwater beach

Holy Water Beach, aka Beach Cathedrals located in the northeast of Galicia, on the shores of the Bay of Biscay.

Geometrically correct 30-meter arches grow out of the water, reminding romantically inclined people of the vaults of a church cathedral. The impression is further enhanced when, at low tide, the strip of land between them is exposed.

For lovers of landscape photographs, special trails have been laid at the top of the slopes, from where they offer views of the gigantic arches. When the tide goes out, tourists can go down and walk on the still wet sand until the next tide.

Warm beach in the North

Northern and warm is the Icelandic beach of Neutholsvik. Despite the fact that it is located on the 63rd parallel (Russian Arkhangelsk is only 1° to the north), it is quite suitable for beach treatments. In addition to a narrow strip of sand, which is sandwiched between a rocky slope and the ocean, there are artificial pools with thermal water, and warm changing rooms with shower. Extreme enthusiasts can also swim in open water— its temperature in the lagoon usually does not exceed 10 °C. From time to time you can meet daredevils here wearing socks and gloves (this way you can avoid cramps), although from the outside it seems that a full-fledged wetsuit is more appropriate here. The beach is free and has urban status, as it is located practically behind the Reykjavik airport, which is why it is very popular with both visitors and the local population.

Beach with airplanes

Maho (Saint Maarten Island, Caribbean Sea)

A small “piece” of the Netherlands nestles in the Caribbean Sea. The island of Saint Martin has a very limited area - only 87 km², slightly larger than the Central District of Moscow. But life here is in full swing: residential buildings, hotels, small industries, and even some agricultural land remains. There is also an airport here - one of the most dangerous in the world (others): the standard runway size for international airliners is approximately 3500 m, but here it is only 2300 m. Behind the airport fence is a beach where tourists sunbathe. And this is the only beach in the world that is lined with signs with aircraft arrival times and posters warning you that the air flow from an airplane can knock you off your feet. However, this does not stop airspotters—people who are keen on watching airplanes—even despite tragic incidents (in July 2017, a curious New Zealand vacationer was knocked down to death). Huge airliners take off and land directly above the heads of vacationers, the distance from the bottom of the plane to their heads is 30-40 m!

Green Beach

“Hawaiian Diamond” is the native name for Papalokea Beach, located on the southernmost tip of the Big Hawaiian Island. The small oval bay, fenced by a rocky shore, has excellent conditions for relaxation: warm sea and wide sandy coast. Only the sand is not quite simple; it is based on the semi-precious mineral chrysolite. An increased concentration of olivine (the second name of the mineral) creates olive-colored sand, which can change to a dirty swampy shade.

Unfortunately, the green sand of volcanic origin is gradually washed away by the surf and the area of ​​the unique beach is decreasing. It is strictly prohibited to remove sand from the beach, even if I remember this - the local police are monitoring this. Visiting the beach is free. You may have to pay locals to give you a ride to the beach - this usually costs $15.

Shell Beach

Shell Beach, Shark Hall. 45 km from Danhill (Australia)

A paradise for shell lovers lies in Western Australia. The beach stretches in a narrow strip for 120 km. During its existence, it became covered with a huge layer of shells of the most different types. The water polished their surface and smoothed out the sharp edges, making souvenirs pleasant to the touch and attractive to look at. For hundreds of years, hurricanes carried marine organisms here, forming a layer up to 10 m thick. But there is one thing - collecting shells is prohibited. The beach is a World Heritage Site. Police patrols monitor the behavior of tourists. In addition, when departing from the country, your luggage is carefully searched, and it will be difficult to explain to the authorities where you got a set of shells in your bag. However, there are no limits for walks and photographs!

Jurassic Beach

Near Lyme Regis (West Dorset, UK)

Near the small village of Lyme Regis you can see creatures that lived on earth more than 100 million years ago. The local beach is a real exhibition of fossils under open air. The coastal strip harbors millions of ammonite specimens that witnessed the age of dinosaurs.

Fossils from the Triassic period, well preserved in soil and seawater, provide insight into the history of the planet. Unlike the two beaches described above, here tourists can freely take the shells they like with them - the authorities do not prevent this at all. The fact is that frequent landslides constantly reveal new layers of fossils, updating the “exposition”.

And Lyme Regis simply lives by its natural heritage. In addition to the many souvenir shops, even the lampposts on the city's embankment are made in the shape of ammonites.

Salty beach

Most of the salt in Russia is mined from a lake in Astrakhan region. The area around Lake Baskunchak is distinguished by a riot of colorful landscapes. The lake itself has a salt concentration lower than the Dead Sea (300 ppm versus 350), but drowning in it is also impossible - often people just lie down on the water, pick up a laptop and watch movies while swimming.

The bottom of the reservoir is covered with a layer of table salt 8-10 m thick. The lake is located on top of a huge salt massif, which goes hundreds of meters deep. Minerals have a beneficial effect on the skin and help eliminate toxins.

Hot Beach

There is a beach on the North Island of New Zealand that is visited by more than 700,000 people every year. The area is not distinguished by its aesthetic appearance or water features. The property of the area is hidden from view and becomes accessible at low tide: underground water flows here. thermal rivers, carrying hot water into the ocean. When the sea line retreats, the sources come to the surface. Temperature underground water reaches 64 °C. Shops located near the beach offer rentals of shovels and buckets - tourists can easily make themselves an impromptu geothermal bath by digging a small hole in the sand.

The most desired and warmest time is inexorably approaching - summer. It is that time of year when all worries fade into the background, when life takes on new colors, when dreams begin to come true.

And many people want to spend these long sunny days somewhere far from home, where reality dissolves in starry nights and the sound of the surf.

And if you are a fan active image in life, if you don’t particularly like to climb mountains or cross forests, armed with a tent and canned food, but rather have a measured and “lazy” holiday, then your paradise is probably the beach. Where else if not on the golden warm sand you can relax and forget about your problems?

Plunge into the dark expanses of the seas or oceans or, with childlike spontaneity, indulge in such an activity as creating beautiful sand castles?..

It is curious that the beach was formed as a result of symbiosis natural factors and active human intervention. Thus, at the beginning of the last century, from explosions during military exercises, the blast wave caused severe destruction of stone, and volcanic activity rock formations completed the matter.

Now Las Islands Marietas is a national park protected by the state and included in the UNESCO World Heritage List. The impressions from your stay in this fantastic protected corner of Mexico will remain with eyewitnesses forever.

"Glass" (California, USA)

"Glass" beach, located in national park McCarrickara near Fort Bragg in California is another result of the joint work of nature and the negative impact of man.

An amazing beach with colorful glass pebbles owes its formation to a city dump. This place in the early 20s of the twentieth century was chosen for a garbage dump; later (at the end of the 60s), the authorities closed the beach and moved large garbage to another area, however, some of the small waste - piles of broken glass, plastic and other things , and remained homeless on the shore under the scorching rays of the sun. Over the next few decades, real miracles happened.

The surf cleared the beach, polishing the broken glass to absolute smoothness. Now this amazing corner of the earth attracts tourists, sparkling and shimmering with all the colors of the rainbow in the sun. This is how nature turned trash into a real treasure!

Extreme Maho Beach, Netherlands

Maho Beach is the most extreme beach on earth. It is located in the southwest of the island of St. Martin, part of the Netherlands.

This amazing place not only remarkable for its azure-clear sea, snow-white sand, warm sun and palm trees. People go here for thrills, because this is the only beach in the world where planes fly literally a few meters above the heads of sunbathing tourists, to their horror and admiration at the same time. The point is that located here international Airport named after Princess Juliana is one of the largest in the Caribbean, it is among the most dangerous on the planet. Its runway starts almost on the beach (only 2,180 m). The noise of an airliner landing is incredible, but, nevertheless, it does not scare away curious tourists. The spectacle is, of course, very impressive, but do not forget about precautions, which is why there are warning signs everywhere. There is a bar next to the beach where all the pilots' conversations are broadcast through speakers in real time. And, despite the extreme conditions of takeoff and landing, not a single accident was recorded at the airport.

Pink Sands Beach Harbor Island

Another gem Caribbean Sea is Pink Beach, located on the east coast Bahamas Harbor. The uniqueness of this place is that the smallest corals and marine organisms have colored the sand a fabulous pink color. Sounds very romantic. And it looks the same - clear azure waters

The Atlantic waves caress the amazing sand the color of rose petals. This is truly an idyllic embodiment of heaven on earth! It is impossible not to fall in love with the fabulous creation of nature. Pink Beach is one of the most photographed beaches in the world and is often used for wedding ceremonies.

It is unusual in that at night it lights up with millions of lights, as if the water is illuminated with neon bulbs from the inside. Tourists call Vaadaha the “Sea Of Stars” on earth. This is unique a natural phenomenon is explained by the chemical processes of living organisms - bioluminescence, during which the released energy produces the substance luciferin. This substance, reacting with oxygen, is transformed into a unique sapphire glow. The coast of the island becomes especially bright and fantastic during the plankton breeding season. Such romantic neon splendor fascinates tourists and will remain in their memory for a long time!

White Beach - Hyams Beach (snow-white sands)

On the east coast of Australia, among the many beaches south of the city of Sydney, a unique beach Hyams Beach, known as the whitest beach in the world.

Also, this sand, which looks and feels like flour, is considered the finest-grained and cleanest in the world. It is used to polish silver and make glass and lenses for telescopes. But as beautiful as the sand is, it is also dangerous because of its dazzling snow-whiteness, so when going to this beach, you should not neglect sunglasses. It’s worth not forgetting that white sand reflects the sun’s rays more strongly, so the tan will be more active.

After waiting until evening, you can enjoy the incredibly beautiful glow of the sugar-white sand. The local landscape enchants all its visitors. This is truly a heavenly place!

Disappearing Chandipur Beach (India)

IN eastern India On the shores of the Bay of Bengal you can observe a unique natural phenomenon. Here on Chandipur beach twice a day the sea plays hide and seek with tourists, thereby delighting them. The fact is that during a huge low tide, the beach strip increases by 5 km, allowing vacationers to walk along the exposed seabed for several hours and explore some of its secrets. underwater world and its inhabitants. However, by the time of high tide, it is better for tourists to “meet the sea” while sitting on the shore. The beach is surrounded by towering dunes and casuarina bushes. Swimming here is possible only during high tide. This magical trick of the sea is a popular entertainment among tourists.

This natural miracle can be seen among the desert northern shores Ireland. The giant road made of hexagonal tiles is admirable and simply breathtaking. And you immediately begin to imagine for whom this road was laid out and who built it? Probably, when creating such a miracle, supernatural forces were involved. If you look from above, you can see along coastline paved road 275 meters long. This road leads into the ocean, towards the north for about 150 meters. Columns with a clear geometric shape (hexagons, although other shapes are also found, but rarely), like honeycombs, fit very tightly to each other. The height of the pillars varies - from very small - a few centimeters to twelve meters. The tops of these powerful columns form a kind of sea springboard, which originates at the foot of the cliff. This unique road goes into the sea and “dissolves” in it.

There are many legends associated with this trail, all of them are interesting and worthy of the attention of tourists. But scientists have put forward their view on the appearance of this mystical road. This is the most popular attraction Northern Ireland today owned by the National Trust and declared a UNESCO World Heritage Site.

When you get here, you immediately remember bowling. It’s as if some giant scattered the balls after a bowling game and forgot to put them away. A stunning picture appears at low tide, when these balls are best seen. Who scattered them? Although the balls are “laid out” suspiciously symmetrically. The secret is that the beach is surrounded by rocks. And over the course of hundreds of years, the surf polished these boulders, and they really became like giant bowling balls. Rocks are very hard because soft breed they were “washed away” by sea water. The sea still has a lot of “work” to do, because the rocks surrounding the beach are made of soft rock, which means new balls will appear on the beach.

Merseyside Crosby Beach, (England)

Completes the top ten amazing beaches Merseyside beach, located in England on the shores of the Irish Sea. This place is amazing with its design. The landscape installation “Another Place” by sculptor Antony Gormley is located here, which is a composition of 100 cast-iron figures facing the sea, standing at different distances from each other. The height of each pedestal is 189 cm and weighs about 650 kg. The mold for casting the cast iron people was made from the body of the master himself. During high tides, some sculptures partially, some completely disappear under water, and at low tide they reappear. Locals They call this beach “The Beach of the Drowned.” It is quite a unique and mesmerizing place.

When we hear the word “beach”, a typical image usually pops up in our minds: sun, palm trees, blue waves and white sand, in general, a standard beautiful picture. However, there are many beaches in the world that can destroy all your established stereotypes about what a beach should look like. This selection contains the most unusual, unique and even strange beaches in the world.

15 PHOTOS

Amazing glass beach near the city of Fort Bragg, it was formed as a result of the dumping of garbage from the city onto the beach in the first half of the 20th century. After the city authorities closed the landfill, the crushed glass was washed by the sea surf for decades until it turned into smooth, colorful pebbles.


The unusual beach was formed at the beginning of the 20th century, after the Mexican military used the islands as military training grounds.


The magical glow on the Maldives beach is thanks to bioluminescent phytoplankton. Thanks to the chemical reactions that occur in millions of these living organisms in the water, blue and bright turquoise illumination appears.


Sometimes water and wind can do some pretty amazing things, and one of the many proofs of this is the stunning beach at Ribadeo. The arches, cavities in the rocks and natural labyrinths truly resemble the architecture of classical religious buildings.


The pink sand on this beach was formed by mixing with corals crushed by the sea surf.


Maho Beach is located in the southwestern part of the island, near runway airport. Due to the small size of the island, the airport is located next to the beach, and therefore airliners approaching to land fly literally over the heads of vacationers.


It is unlikely that you will be able to sunbathe and swim on Jökulsárlón beach, since the weather there is almost always cold. However, the beach is worth a visit to admire the beauty of this place, where the black sand formed by volcanic eruptions contrasts amazingly with the mass of ice pieces.

The green color of the sand on Papakolea Beach is given by particles of peridot, a semi-precious mineral of volcanic origin. The beach is open to the public, but guests are prohibited from taking even a handful of sand outside the beach.


These fantastic pillars are actually petrified and cracked basalt lava. They formed about 50 million years ago.


The black sand on the beach was the result of lava that quickly cooled in the sea.


The main reason for the red color of the sand on Rabida Beach is the oxidation of the volcanic soil by iron oxides. Coral deposits on the shore can also give it an unusual color.


13. Shell Beach in Shark Bay, Australia. 15. Cave beach in Algarve, Portugal.

Coastal cliffs in the Algarve are made of limestone, which is easily influenced by wind and water, resulting in the formation of such amazing caves.
