- There's nothing more
relaxing or refreshing than taking a dip in the
pool on a scorching hot day, but not all pools have
the same azure appeal. Around the world some total psychopaths have built their baths
teetering on the edge of cliffs, perched on the very tops of skyscrapers, and even dug them deep underground. And with that, it's time
to grab your water wings, take a deep breath, and say your prayers as we dive into some of the
most terrifying swimming pools around the world. (wind whooshing) House of Horror. In the quiet hilltop town
of Montalcino, Italy, there lies a big empty house
made from an imposing facade of old stone. If you dared to step inside, you'd find a swath of cold gray rock, and eerily plain marble features, like a bleak scene plucked
out of a horror film. Venturing even further in,
you'd eventually discover a mysterious unmarked door. And it's behind this door
down an ominous set of stairs that this strange isolated
body of water lies in wait. To me, this long underground
pool is the very definition of claustrophobia. There's no natural light, only an eerie artificial glow
from beneath the surface, making the narrow tunnel like room more like an underwater
crypt than a relaxing pool. Fortunately, this isn't the
layer of anything sinister, rather it's the work of
architects Pignattai and Vossaert, and lighting designer Davide Groppi, who worked hard to recover and restore this once abandoned house. Supposedly, below lighting
is designed to invite and welcome people into
different parts of the home, but who is it supposed to be
inviting to exactly? Vampires? (wind whooshing) Chilling Chernobyl. When the reactor in
Chernobyl's Nuclear Power Plant famously exploded back in 1986, deadly radioactive fallout
was flung for miles across Ukraine, from Russia,
and even as far as Canada. Considered the worst
nuclear disaster in history, the area surrounding Chernobyl
was immediately evacuated, but the levels of radioactive
contamination were so fatal that for the most part, the area's been left abandoned ever since. This pool in the nearby
town of Pripyat, however, remained open for 12
years after the disaster. But why would anyone hang around in such dangerous conditions for a swim? Well, Pripyat, wasn't
completely abandoned. A team of heroic people
called liquidators, were tasked with decontaminating
the town at severe risk to their own health. They worked long hard hours
doing their very best, to limit the damage caused
by the huge nuclear blast. So, can you really blame them for wanting to take a relaxing dip in the
pool at the end of the day? Following a health inspection in 1988, the pool was shut down for good. And today, it sits in
spooky silence as a sad and scary reminder of the
once bustling community that lived there. But after the site was
declared safe in 2011, it became something of a dark alternative tourist attraction. No, I doubt these
tourists will be bringing their bathing suits along anytime soon. (wind whooshing) Dipping with the Devil. Before you can reach this
petrifying pool in South Africa, you'll need to traverse a
treacherous rock strewn path until you come across running water. Then, you'll know you've
reached to the River Zambezi. From here, simply jump
in and swim down current towards the massive
crashing Victoria Falls and try not to think
about what would happen if you fell off the edge. Though, that might be hard
because the location of this pool is right on the precipice
of the waterfall. The strangely calm area
of water is separated from the shocking 328 foot drop below, by a thin lip of rock that's
been slowly eroded away over thousands of years. So it's no surprise that
this place has become known as the Devil's Pool. And not that that stops
thrill seeking tourists from jumping in without
a care in the world. Personally, I'd be too worried about that lip of rock breaking off
and sending me plummeting down with it. And considering more than
100 million gallons of water rocket over the falls every minute. It's just a matter of time
before that lip goes hurdling over the edge as well. I don't think I'd want to
be posing for a selfie there when that happened. (wind whooshing) Shivers in Shanghai. If you're scared of heights, you might want to avoid the
Modern Holiday Inn in Shanghai, which boasts a swimming
pool that is definitely not for the faint of heart. On the 24th floor of
the towering building, the pool juts out from the side and hangs over the streets below, which are a dizzying 230 feet down. And if you thought that was scary, it's also got a glass bottom. So the people below can watch
you as you desperately try to swim back to safety, or is
that just what I'd be doing? Of course the pool really is safe, but it sure doesn't look like it. The design is cantilevered, which means it's made
from a single long beam, that's only supported at one end. And while this sounds like a
disaster waiting to happen, it's actually a strong structure, and is often used in bridges. But even with this knowledge, I still don't fancy stepping foot in it. (wind whooshing) Nerve-wracking Nemo. If somebody mentions the name Nemo to you, you probably start thinking of
a friendly talking clownfish, not a terrifying waterfield trench, that looks like it descends
into the darkest depths of hell. So this diving facility called it Nemo-33. Doesn't actually lead to Satan, but it does drop down a
death defying 113 feet. That's about as deep as a
10 storey building is high. Divers come to Nemo-33
because it lets them practice their deep water diving skills, without having to make
a long trip out to sea. the relatively shallow upper
pool features a circular pit that if you're not too scared, you can follow all the way down into the inky blackness
below, and at the very bottom, there's simulated caves
and underwater tunnels that sound like a
claustrophobe's worst nightmare. But what does it feel like
to be more than 100 feet below the surface of the water? Well, at that daunting depth, you have about four times more
pressure pushing down on you than you'd usually have on land. This restricts the amount of
air your lungs can breathe in as they're squeezed by the immense weight of all the water above you,
it could be easy to panic. However, with the right amount
of training and experience, it's still a safe diving
depth for most people. Though, it's probably a
good idea to start out in the shallow section first. I mean, you don't wanna throw yourself in at the deep end. (wind whooshing) Tallest Terror. The skyline of the
lavish city of Singapore, is a glittering collection
of truly spectacular sights, but it's the Marina Bay Sands Hotel, that boasts one of the most impressive and widest attractions around. Sitting proudly on the rooftop, this infinity pool once held the record for being the highest
swimming pool in the world. At a jaw dropping 650 feet high, the pool is perched on the 57th floor, giving swimmers the most
amazing view of the city below. What's more, it stretches almost 500 feet, from one side of the $6
billion hotel to the other. That's almost three Olympic
swimming pools in length. However, as impressive
as this structure is, it's also terrifying. Because this once record breaking pool, doesn't have any rails, or at least not any in
the traditional sense. There is a protective ditch
running around the edge of the pool, but looking over the small
barrier at the cityscape below, still sends a shiver up my spine. Unlike the height wasn't daunting enough, these hotel guests are
swimming up so high, that they occasionally witness lightning from their pool top perch. (crowd exclaiming) If that's not assigned
to get out of the pool, then I don't know what is. (wind whooshing) Horrifying Hubertus. At Hotel Hubertus in Italy, visitors can choose to enjoy
a relaxing sauna experience, a workout in the gym, or a swim in one of the most terrifying
pools in the world. The 84 foot long marvel
juts out from the very top of the hotel, leaving it levitated around 40 feet in the air. Compared to Shanghai's sky high pool, this is hardly off the ground. So this design isn't all that scary, nor at least it wouldn't be, if only it weren't entirely supported by what looks like a few lone tree trunks. And just to remind swimmers
that their fate hangs in the balance of these trees, there's a glass panel in the bottom so that they can look down
at the cold hard ground, 40 feet below. Fortunately the trunks
are actually encasing strong steel columns. So they only look dangerous. But if you went up there
without knowing that, the feeling that four spindly wooden poles are all that stand in the way of you becoming a flattened man
cake would not be pleasant. So fancy testing the
limits of your bravery. Well, for a whopping $400 a night, you too can slip on a pair of Speedos, and investigate whether
those beams are strong enough to support all the holiday
pounds you've put on. (wind whooshing) Water Fall. Chilling in the pool can
be one of many highlights of a vacation, but what occurred with one particular pool at a beachfront condo in Brazil, one night in April, 2021,
was far from relaxing. Just before 10:00 PM, residents
of the Parador building heard a big bang, and
rushing to their windows, they were met with a terrifying sight. It turned out the 75 foot
long pool on the rooftop of the building, had collapsed sending thousands of gallons of water crashing onto the car
park below. Crazy, right? Luckily, nobody was hurt and
all 270 guests were evacuated from the building, and rehoused for free. But some of those people
had used the pool mere hours before the floor gave way. Maybe you're braver than I
am but if pools collapsing is something I now need to worry about, I might give up swimming altogether. (wind whooshing) The Dirt Sea of China. Despite its name, China's Dead Sea Resort is far from lifeless. Back in 2013, the country
was hit by a heat wave so extreme, that Shanghai
experienced hottest July, in 140 years. And in Daying County, temperatures soared above
100 degrees Fahrenheit. This led to thousands of
locals flocking to the resort, in desperate need of
a cool refreshing dip. Giant inflatables in hand,
adults and children alike, all jumped into the crowded indoor pool, and before long, the
situation was overflowing quite literally. Despite an impressive
capacity of 10,000 people, the pool was overwhelmed by
the sheer number of hot humans, who totaled about 15,000 before admissions were finally disallowed. Oh God, just think of this smell. And oh no, that taste. There's no way that pool
was filled with just water after the influx of
sweltering, sweaty people, and nevermind the hygiene though, it's a miracle everybody
escaped with their lives. With that level of overcrowding, if you slipped under the surface, there's a chance you
might never come back up. I don't know about you, but drowning in a sticky sea of other people's body fluid is, that's pretty low on my bucket list. (wind whooshing) Poolside Poltergeist. Resting in Long Beach Harbour, California, lies a ship that in its
heyday was bigger, faster, and more powerful than the Titanic. This is the Queen Mary, a colossal cruise ship
built way back in 1936, with an impressive history
as a World War II vessel. Although, it was this war time involvement that led to it being the site of at least 49 daunting deaths. And even though the ship was
retired more than 50 years ago, it's far from quiet today, docked up as a tourist attraction, as many as 150 spirits,
supposedly lurk on the ship, and the First-Class swimming
pool is one of the hotspots for the ghastly ghouls. It's long been devoid of any water, but that doesn't seem to put them off. Visitors to the ship
claim they've seen women in 1930s style bathing suits, wandering around the poolside. As well as a young girl,
clutching onto a teddy bear. What's more? The sounds of
splashing have been heard echoing around the dark chamber. Wait, does that mean
you can get ghost water? Ah, well, I wouldn't be
sticking around to find out as this place is undeniably creepy whether you believe in phantoms or not. So I can safely say this
is one swimming pool you wouldn't catch me dead in. (wind whooshing) Caged in the Cove. Do you like the idea of being
locked in a tank underwater encircled by huge hungry crocodiles? Well, if you do, Crocosaurus
Cove in Australia can arrange it for you. Visitors to the reptile
park relish in the terror of its main attraction enticingly
called the Cage of Death. The cage itself is an acrylic
tank that you climb inside before the super kind
park staff lock you in. Then you're lowered into a pool
with the colossal crocodile. Just in time to watch the
16 foot beast rip and tear its latest meal to shreds. So you can observe as the
crocodile begrudgingly eats the meat it's been given, all the while eyeing the
much tastier morsel floating in the cage nearby. Thankfully, there have never
been any major incidents at the park, but about 10 years ago, the cage did break, and two
people were left stuck inside. Luckily, staff responded fast, and got them out without any harm. Phew! It's a good job
they acted so snappily. (wind whooshing) Serious Sinkhole. Although it's not a man-made pool, this massive mysterious
circle of water off the coast of Belize in Central America, has attracted daring divers for years. At almost 1000 feet across
and over 400 feet deep, it's the world's biggest sinkhole, and has been imaginatively
named The Great Blue Hole. Sinkholes are caused by a
collapse in the surface layer of rock often due to erosion. When the rock collapses, it can unveil underground
and underwater caverns. Here, the sinkhole descends so deep, that sunlight from above
can't reach the inky blackness at the bottom, but that's not the scariest
thing about this giant hell hole because there are hundreds,
if not thousands of sharks, that patrol this area too. Thankfully, the sharks
only swim where it's light. So you probably wouldn't
get a jaws style surprise if you decided to venture
into the darkness. But scientists have discovered
something far more unsettling than sharks down there in the gloom. Using sonar technology, they mapped the entire
underwater pit and found tracks at the very bottom that, get
this, they can't identify. So something has been
lurking on the pitch black of the ocean floor, and we
have no idea what it is. Could the Great Blue Hole be the layer of some legendary sea
monster, like The Kraken? Or maybe Godzilla? What do you reckon? Let me know what you
think's lurking down below in the comments. (wind whooshing) Texan Tall Pool. 500 feet above the busy
streets of Houston, Texas, people can swim in a pool that's far away from all the hustle and bustle down below. It actually sounds quite
relaxing if you ignore the fact that the bottom of the
pool is completely clear, and juts out from the 42nd floor of the residential Market Square Tower, the transparent base is
curved with no hard edges, and makes it seem as if you're
really floating in the sky. I was sure this brave man was
about to fall straight off the edge. (water roaring) (exclaiming) I felt my stomach
churn just watching that, but although it looks like you
could fall through the floor at any moment, it's made from eight
inch thick acrylic glass. So the chances of an accident
happening are incredibly slim. Acrylic glass is stronger
than normal glass, and transmits light at a
similar wavelength to water. That's why the view
through the pool's bottom is crystal clear. So I'd be more worried about suffering a wardrobe malfunction and
flashing my birthday suit to the whole world. (wind whooshing) Panoramic Terror. Imagine a swimming pool
so gut wrenchingly high that you could see the whole
of London city glittering like a toy town below you. Now, imagine this pool
makes up the entire rooftop of a skyscraper with transparent walls, and 360 degree views of the city. So you're getting an idea
of the hair raising concept that's in store for England's
capital in the next few years. While this insane infinity pool is only in the planning stage, if built, it would be the
first ever of its kind, and it's planned to
tower over the cityscape at a whopping 656 feet high, a whole 66 feet taller than
the neighboring Gherkin tower. Much like the Market Square Tower's pool, the whole thing will be
made from acrylic glass, both of the walls and the bottom. So it'll look like you're
floating high above the city with nothing in between you,
and a 55 storey fall, yikes! But hold on a moment,
just how are swimmers meant to get in and out of
this sky high swimming pool? According to the designers Compass Pools, at certain intervals, a tube
encasing a spiral staircase, will rise up from the pool
floor using hydraulics, coming to rest very slightly
above the water's surface. A special pump will empty the
staircase tube of the water that rests inside it
while the pool's in use, depositing it back in
storage, and enabling swimmers to safely enter and exit
the pool via this staircase, which connects the pool
to the floor below. This design couldn't get
any crazier if it tried. What'll they add next? A water slide on an adjacent building, maybe a diving board off the edge. What do you think? Let me know down in the comments. (wind whooshing) Predators at the Pool. Across the baking-hot plains
of Tanzania in East Africa, a plethora of dangerous animals wander the rolling wilderness. From enormous elephants to roaring lions, it's a risky place to explore on your own, and knowing that, would
you be brave enough to hang out in a pool
that directly overlooks one of the animal's
favorite watering holes without any kind of protection? Well, the Four Seasons Safari Lodge inside Serengeti National
Park, has just such a pool, a mere 25 feet away from
a spot the elephants love, with no fences or barriers of any kind. The pool is so close that if
it weren't for the difference in color, it would be
hard to tell where it ends and the watering hole begins. Considering crocodiles lurk in the waters of the Serengeti though, I'd be worried about getting too close. Moreover, although rare,
leopards and lions, prowl the area too
searching for fresh meat, and nothing ruins a day in the pool quite like being eaten alive. (wind whooshing) Precarious Pulpit. A huge 2000 foot tall cliff, a bone breaking plummet into
the freezing cold waters below, and nothing to stop you
hurdling off the edge to your icy doom. Does that sound like a good
place to build a swimming pool? I don't think so either, but the people who designed
this next monstrosity are confident in their vision. Pulpit Rock in Southern
Norway is a tourist attraction in its own right, where people flock just to
take in the amazing views, of the surrounding Lysefjord. But back in 2019, architectural
studio, Hariya Atak, proposed transforming the
rock face from this, to this. The structure bolted into
the cliff face itself, is actually a five star hotel, complete with several snazzy balconies, that are guaranteed to give
a great view of the area. The crowning jewel though, is the long thin strip of pool
jutting out at the bottom, or the world's most
death-defying water feature, depending on how you look at it. The entire oblong structure is planed to be completely see-through, giving a heart wrenching
view of the chasm below, to anyone brave enough to swim in it. Just picture yourself doing
a forward stroke over this. Thankfully, this design
is still just a concept. Otherwise I'd be saying no way to Norway. (wind whooshing) Written and Red. If you love reading books
outside in the sunshine, then the Library Resort
on the island of Koh Samui in Thailand, might just
be your dream getaway. With a distinctly literary theme, smaller guest rooms are called Pages, with the larger suites called Chapters. But the resort also
hosts a more malevolent looking attraction. I mean, it looks like someone
had a really gruesome accident in this pool, and I'm not
talking about eating in it. Fortunately, the blood red
color is just a creepily, clever illusion, an intricate
pattern of orange, yellow, and red mosaic tiles, adorn the
inside of the swimming pool, making the water within
seem like it's been tinged to blood red. The illusion only works
because the depth of the pool is just right. All water has a slightly blue tint to it, so despite the tiles, the pool would actually
appear blue like any other, if it were much, much deeper. Well, as much as I understand that, I'm still not sure what this
bright red color has to do with the library theme. I mean, nothing I've read so far has, "Oh, up there it is, it's very clever." (wind whooshing) Scary Sky Pool. Ah, London, the city of
Big Ben, Buckingham Palace, and a super scary, transparent sky pool. Hold on what? This attraction
only opened in 2021 and is a joint venture by
engineers, aquarium designers, and even architects, who worked
on the Sydney Opera House, that explains the sleek modern look. But as inviting as the water is, it's the view through the bottom
that people come here for, the clear acrylic floor
gives swimmers a perfect view of the 100 foot drop below them. And with clear sides too, the breadth of the view is unparalleled. Of course, it's not for everyone. Particularly, people
who suffer from vertigo or common sense. But as long as there are no
more than 19 people in it at a time, it's designers
claim it's just as safe as being on the ground. Hold on, does that mean
if 20 people go in, the whole thing will come
crashing down to earth in a big splash of water and swimsuits? I know it rains a lot in Britain, but that would really surprise
anyone unfortunate enough to be standing underneath. (wind whooshing) Heaven and Hell in Hawaii. The next time you plan a vacation, I don't recommend heading
over to Kipu Falls, on the Hawaiian island of Kauai. This small tranquil looking waterfall, was a popular tourist trap for years. Nowadays though the area
has been blocked off because it leads to a
natural pool so dangerous, it's been nicknamed The Pool of Death. The small cove can be reached
if you jump from the falls at the right spot, and in good weather, it looks like an idyllic
place to go for a bathe. 10 foot tall walls of
volcanic rocks around it, and block the powerful ocean
waves for the most part. On good days, the pool is calm, but on bad days, when seas are rough, waves can reach humongous
heights of 15 feet, and come crashing violently
over the volcanic walls. In seconds, the cove can
turn from heaven to hell for anyone unlucky enough
to be caught within. Luckily these kids were okay, but the current can very
quickly pull you under the water onto the jagged rocks, and
back out into the ocean, which is extremely choppy
and dangerous in this area. So this is one terrifying pool I can't recommend even to
the thrill seekers out there. I mean, if it's named The Pool of Death, it's probably a good idea
to stay away from it, but whatever you do, don't stay away from my channel too long, or you'll miss all the exciting content I've got lined up for you. And that's all for now though, so leave a comment down below, letting me know which of these pools, you'd most and least
like to take a dip in, and thanks for watching
