Vous Pouvez Nager Ici, Mais Vous Ne Devriez Vraiment Pas Le Faire

Sympa

Il existe des endroits dans le monde qui semblent vous inviter à faire trempette, mais vous ne devriez vraiment jamais le faire ! Jacob's Well, au Texas, est une source naturelle fascinante, claire et accueillante, mais elle abrite des grottes sous-marines dangereuses qui peuvent vous aspirer plus vite que vous ne pouvez dire « plongeon ». La plage d'Hanakapiai à Hawaï est comme un paradis sur terre, avec ses sables dorés et ses vagues turquoise, mais les courants d'arrachement sont de petits diables sournois, prêts à entraîner les nageurs imprudents au large. L'île Fraser, au large de la côte australienne, est un pays de rêve avec ses plages immaculées, mais les eaux y grouillent de méduses qui vous infligeront une piqûre que vous n'oublierez pas. C'est comme si Mère Nature nous rappelait que la beauté peut venir avec morsure, ou dans ce cas, une gorgée.

00:00Are you ready to dive into the most dangerous waters of the planet?

00:05I'm kidding. Of course, put away your swimming gear and believe me, it is much safer to observe them from a distance.

00:13Some waters are infested with sharks, others are full of acid, and honestly, I don't know what's worse.

00:20Maybe the ones that are so deep and scary that many divers never come back.

00:25It's up to you to choose your worst nightmares.

00:29If you have already visited Texas in the summer, you know how overwhelming the heat can be,

00:34and jumping into an icy water without hesitation can seem seductive.

00:38The Jacob's Well, with its bright colors and its almost supernatural atmosphere, seems to be the perfect place for it.

00:45Discovered by the first colonists in the middle of the 19th century,

00:48this boiling hole of water up to 1.5 billion meters high was considered a good source of drinking water.

00:55The well has an average depth of 36 meters and is reputed to be the second largest cave entirely submerged in Texas.

01:03The fresh water of this well attracts the audacious who dive there from a ditch nearby.

01:09Personally, I would go there. And you?

01:13Some divers go down to 30 meters and make a path through the passages of the underwater cave.

01:19And everyone says it's not a healthy walk.

01:22Several people have never returned from the well, which is why it is said to be one of the most dangerous diving sites in the world.

01:30The underwater passages become so narrow in some places that you risk getting stuck with all your equipment.

01:37Another problem is the extreme depth of the cave.

01:40Even at the surface, the danger is present.

01:43Its diameter is only 3.6 meters, and the surrounding rocks increase the risk of injury by diving.

01:49If, despite all this, you still want to try the adventure, know that a special authorization is also required.

01:57Let's talk a little about the beach of Anacapiai in Hawaii, which embodies the image of the paradise beach,

02:03but should have its photo in the dictionary to accompany the definition of danger.

02:08If you decide to visit it, you will notice a wooden panel listing the number of divers who have never surfaced.

02:16You will see more than 80 brands, and this figure is not official.

02:20So they could have more.

02:22The main danger lies here in extremely powerful rip currents, coming out of an unpredictable swell.

02:29The absence of reefs in this area allows the current to flow smoothly.

02:34If you are adventurous and decide to go into the water,

02:38know that if you are caught in a rip current, the closest shore will be about 10 km away,

02:45which will considerably reduce your chances of survival.

02:48In addition, the beach is so isolated that there are no rescuers nearby,

02:52which means that you will be alone in front of the ocean.

02:55And it is he who has a strong chance of winning.

02:58This is why Anacapiai is not recommended even to the most experienced swimmers and surfers.

03:03Fortunately, Hawaii is full of beautiful beaches, and you will certainly find an alternative for your escape.

03:10Kogari, or Fraser Island, if you are rather old game, is famous for its fauna and breathtaking landscapes.

03:17But before you venture to the largest sand island in the world, it is crucial that we talk about safety.

03:24The island is populated by dingoes, nothing to do with the charming Labrador of your neighbor.

03:29These animals are unpredictable and potentially dangerous to humans if provoked.

03:35Never feed them, do not interact with them, and keep your food and your belongings on you to avoid attracting their attention.

03:42Believe me, it's better.

03:44The next threat are the snakes hidden in the tall grass.

03:48Walkers must stay on the marked trails and be particularly careful at night.

03:53The island also houses some particularly venomous spiders.

03:57And if you think you can escape this fauna by swimming, you are wrong.

04:02Large white sharks and bulldog sharks patrol the waters.

04:06You can meet them as soon as the water exceeds the level of your knees.

04:11In addition, the currents are particularly powerful here, and the ocean conditions can change quickly,

04:18sometimes giving the impression of being calmer than they really are.

04:22There is no rescuer to help you in the event of a problem, and you swim at your own risk.

04:28And if you count on your phone to call for help, know that the network coverage is very limited in this area.

04:34The weather on the shore can also change without warning, bringing sudden storms, violent winds and temperature variations.

04:44Our next destination of the day is the Blue Lagoon.

04:47But don't get carried away.

04:49This is not a magnificent spa in Iceland, but its British version.

04:54Swimming here is like diving in javelin water.

04:57Isn't that your favorite hobby?

05:00Neither am I.

05:01Authorities continue to issue warnings to dissuade people from swimming there.

05:05This ancient limestone quarry in Harpur Hill is probably one of the most dangerous waters in the country.

05:11These tropical waters of a striking blue have a very high alkaline pH due to the dissolution of limestone.

05:18Despite this, thousands of people go there in hot weather.

05:22Your skin, your eyes and your stomach will not thank you for this visit.

05:28You could also suffer a thermal shock due to the temperature of the water,

05:32where you bump into one of the many objects that have been thrown over the years,

05:36car wrecks with household waste.

05:39In March 2020, the situation became so worrying that the waters of the Blue Lagoon were even tinted in black to dissuade potential swimmers.

05:49In August 2014, residents of the region discovered a lake in the middle of the Tunisian desert.

05:55With the intense heat that reigns there, it would be understandable that you would want to throw yourself there immediately.

06:02This new water plan was nicknamed the Mysterious Lake and has indeed become a great enigma.

06:08Hundreds of people came to swim in this clear and fresh water.

06:12But a few days later, the lake turned dark green.

06:18The fishermen continued to swim despite everything.

06:21When scientists and geologists arrived, they noticed that this lake was full of stagnant water.

06:27It was not fed by underground watercourses or by the rains.

06:31This is how the water became muddy and crusty.

06:34The lake contained algae and many dangerous bacteria for the human body.

06:39Researchers have also discovered that the soil of this region contained deposits of phosphate.

06:45This substance can decompose, making the water even more toxic.

06:50But even this did not discourage people from swimming in the lake in the middle of the desert.

06:56Its origin remains mysterious.

06:59Some experts think that heavy rains could have filled a depression in the ground.

07:04A more widespread theory suggests that an earthquake would have created the lake.

07:09Seismic activity would have torn the earth's crust above a phreatic map,

07:14allowing underground sources to fill the crack.

07:19In theory, the lake could be emptied as suddenly as it appeared,

07:23so hurry if you want to see it.

07:28Have you ever thought of taking a bath in an old diamond mine?

07:32I do not advise you to try, especially if we are talking about the Big Hole of Kimberley in South Africa.

07:39150 years ago, a flat hilltop was here.

07:43Then, the news spread that big diamonds had been found in the region,

07:48and thousands of people loaded with shovels and picks rushed to the site.

07:53It became the largest excavation dug by hand in the world, and also one of the deepest.

08:00The mine quickly developed, but water infiltrated the pit, and the rocky walls became unstable.

08:06Underground mining with tunnels and wells proved too expensive,

08:11and the mine finally closed after extracting about 2,700 kilograms of diamonds.

08:20Today, the old mine is filled with about 40 meters of water.

08:24This bath here is extremely dangerous, because you do not see the bottom and the walls of the lake are steep.

08:30It would therefore be wiser to embark on your diamond hunting adventure elsewhere.
