San Alfonso del Mar resort in Algarrobo, Chile, has the largest swimming pool in the world. It’s 3,324 ft (1,015 m) long and has a total area of 19.8 acres (8 hectares). The pool holds 66 million gallons (250 million liters) of water, as much as 6,000 normal pools. Incredible!

erm so how much power does it take to run this thing? not to mention the (ecologically) horrendous treatments the pool water is subjected to. The beautiful colour of the ocean next to it makes this whole thing look wasteful to the point of decadence.
Actually, the water in that pool is from the ocean next to it, it has a sistem of pipes that takes the water of the ocean and puts it in the pool, so they don’t use any kinf of treatment. (it even tastes salty, i’ve been there) =)
Really sorry for my english, i’m chilean and it’s pretty hard to talk in a foreign language. ahaha
Take Care!!
You speak perfectly, better than most people who have English as their first language.
no
MIKE ME AN U GOT PROBLEMS SON
Alright why don’t you just kill some kittens while youre at the task of shitting in peoples punch bowls. STFU people like you ruin everything good in life.
oh shut up.
NO COMMENTS?! Thats ridiculous i wanna go
I’m considering putting one of these in my backyard.

Right next to the ocean. A brilliant waste of money. Idiots.
it’s not actually… some people prefer not to swim in the ocean.
And the hotel is huge. I’m sure it takes hundreds of people to help clean the pool.
personally i can’t stand the waves or the sand near me and salt water tastes awful to me.
i much prefer chlorine.
I agree! I prefer a pool over an ocean any day. It’s nice to look at but I have no desire to get in it.
Whales can ejaculate hundreds of gallons of sperm (like 300 to 500 gallons) at a time! ….you other people can enjoy your salty water, personally I’d rather be covered in chlorine (^_^)
I agree with Alison.
I like swimming pools better than beaches.
DO NOT SWIM IN THE OCEAN! if you don’t believe me, check the tide line after the tide goes out. disgusting.
The ocean in Chile is realy cold, with the hubolt current that passes through here…didn’t your mom ever tell think before you speak?
first sorry my english!
i swam in this pool time ago and i went for summer in algarrobo, that beach (called miraflores) is really dangerous! basically you want to swim there… you are dead! the place has some other beaches there but very (VERY!!) far away
The ocean meeting Chile is cold and not very nice to swim in. The pool can stay.
It’s sad sometimes, when people can’t look beyond their righteous environmentally charged opinions, and see a marvel of engineering for what it is.
Ainslie, Im sure the power requirements are nowhere near what you are imagining. Its a tropical location (no need to heat the pool), and the ocean is right there, so its highly likely that it is a saltwater pool, vastly reducing maintenance and need for chemicals.
A marvel of engineering? I see no sign off a slide, wave pool or ‘lazy river’. Boo. Boo to your ‘marvel’. It’s just a big pool. An awesomely big pool.
You’re completely right. To design watertight container capable of holding, cleaning (especially with lower the cleaning/maintenance requirements of a salt-water pool), and of course, not falling apart under the tremendous weight of, 66 million gallons (roughly half a billion pounds) is a trivial task. Any idiot could come up with a structural system that covers 20 acres. And of course his idiot brother could easily design 20 acres of *watertight* pool. No marvel here.
Yes it is easy when you use European and American engineers!
If you’d bothered to use wikipedia or google, you could have discovered that it was designed and built by Crystal Lagoons, a Chilean company that is now building similar pools all over the world.
Here’s a way to throw the money that I just do not understand.
Greetings
Chile’s monster pool uses a computer- controlled suction and filtration system to keep fresh seawater in permanent circulation, drawing it in from the ocean at one end and pumping it out at the other.
The sun warms the water to 26c, nine degrees warmer than the adjoining sea.
Chilean biochemist Fernando Fischmann, whose Crystal Lagoons Corporation designed the pool, said advanced engineering meant his company could build “an impressive artificial paradise” even in inhospitable areas.
“As long as we have access to unlimited seawater, we can make it work, and it causes no damage to the ocean.”
Maintenance costs amount to 0.2% of the constructions costs. Not bad, actually. Next time before you give your opinion,
use Google.

Thank you, Frank! Isn’t it amazing what just a few minutes of research can show us?
This is pointless. The ocean is right there! I absolutely do not understand this..
The water is realy cold, cause of the humbolt current that passes thorugh here…nerd
unless they have jellyfish and sharks in the pool then its not a waste of money to me
not to mention the (obvious) fact that sometimes the ocean will be colder than you want it to be and you can heat a pool
You can also heat the ocean! Let’s do that instead! Its called global warming!
I feel bad for whoever has to clean this thing…
I wonder how they have lifeguards patrolling this monster, jet skis?
I am laughing fairly hard at the lack of reading comprehension from some of the people responding to this article. Some aught to check out the posts before tossing your $0.02 in…just my 2 cents
just thought i’d point out that it was 0.02 PERcent not cents. hah. awkward…
yeah by $0.02 he meant 2 cents (on purpose) not 0.02%. he then uses the same expression but verbally so no, it’s not awkward
The water of the pool comes from the ocean. and that beach is really dangerous, if you want to suicide you just found the perfect place to do it. Also are others beaches in that place that are safe, but the water is REALLY cold and the sea is full of algae, what makes it very disgusting
So, I love how everyone is saying “no one is intelligent in this thread,” and then throwing out random facts.
First of all: It’s the Humboldt stream. yes, with an m and a d. not that spelling matters on the internet, but if you are going to try to sound like you know more than everyone else posting, then make sure what you are saying is accurate.
second of all: Algarrobo, Chile is not a tropical location… Probably the only location that would be considered “tropical” in Chile would be Easter Island. Not even northern-most Chile is considered “tropical” – a hot desert climate at best.
Which still leads to the biggest question as to why such a big pool? As previous people have stated, it doesn’t have water that is much warmer than the ocean water itself. the only use is for people who are scared of the ocean/don’t like waves/prefer “cleaner” water.
I do think the engineering of it is remarkable, but it’s still a decent question to ask for many people – considering so many people visit Chile to see it’s beautiful ocean, surf the waves, etc. It’s just an interesting thing to think about. Obviously it also has to do with tourist attractions, as it IS Algarrobo…
As somebody above noted, the pool is said to be 9 degrees warmer than the nearby ocean water. That seem much warmer to me but ymmv.
These comments are so stupid, I work in a chlorinated pool, and let me tell you, chlorine fucking sucks. The ocean can be gross sometimes but at least it’s all natural and doesn’t fuck up your skin like chlorine.
do you have to stay at the resort to use the pool or can anyone use it?
From what I remember when I went, it’s not even a resort per se. It’s apartments. My friend and I had to pretend we were interested in purchasing a place and go to an open house to be allowed to go walk inside the grounds.
I swear, the stupidity of some of the morons that sit behind a computer and make idiotic comments instead of appreciating things will never cease to amaze me. Get out and travel. Live life. Enjoy the pictures. Sometimes it makes me ashamed to live amongst so many asshats.
No one cares about your unintelligent, negative opinions. Now get back in your basement where you belong.
Do you want us to get back in the basement or get out and travel?
Barry dude, careful…you might have just qualified yourself as a moron just by validating this string!

I would bet that the pool is very functional. The air conditioning for those near-by buildings have a lot of heat to dump and I bet that the pool is it. The concept has been used more than once. It appears to work very well.
Such a waste for a big pool. They should have added sections to it like water slides or wave pools. And I too would feel bad if ever I were assigned to clean this up.
As there was almost no one in the pool, I guess it’s safe to assume only the very wealthy can afford to swim there.
awsome
Im from Chile and someone some day told me that the pool doesnt have any clorine and in stead of this the water is sea water with more salt (actualy tastes saltier).
*someone told me that in a “high people conversation”, i dont know if is true but i believe it is.
Madness, complete and utter madness. Get rid of the ocean keep the pool.
Right. Now someone tell me why this is necessary, lol.
the hotel my uncle own it he’s rich the pool that looking like the sea with blue water

To tell the truth, I thought the pic’s were photo-shopped until I read the comments.
So far I got, the world biggest pool, is right next to the world biggest ocean and it’s got the worlds smallest attendance. Where are the people? I’ve been in a 4 foot round kiddy pool that’s had more people in it. Oh! and the ocean is chilly, the pool is chilly, and it in a country called Chile. Am I missing anything besides the people?
