The Biggest Pool In The World

If you've ever thought your apartment pool was a bit cramped, imagine trying to do laps in a body of water so massive that it makes your local YMCA look like a dog bowl. We're talking about the biggest pool in the world, and it's so outrageously huge that it practically has its own weather system. Water wings and pool noodles have never looked so laughably inadequate.

Meet the Colossus: San Alfonso del Mar

The reigning champion of colossal pools sits in Algarrobo, Chile, at a luxury resort called San Alfonso del Mar. This absolute beast stretches an incredible 3,016 feet long, which is roughly three times as long as the Eiffel Tower laid on its side — because someone clearly felt that wasn't weird enough. The pool holds approximately 66 million gallons of water, which is honestly enough to hydrate a small country if they were really, really thirsty.

To put that in perspective, it's the equivalent of roughly 9,000 bathtubs worth of water, give or take a few hundred. A single day's worth of water in this pool could bankrupt the average household for the next four centuries. Your water bill would need its own water bill.

But Wait — It Gets Weirder

Here's the kicker: the pool doesn't even use chlorinated water. It's filled with filtered seawater pumped directly from the Pacific Ocean, because apparently, regular pool water just wasn't fancy enough for this level of showboating. Imagine the logistics — engineers basically built a private ocean and said, "Yeah, let's just make that a pool."

The pump system that feeds this aquatic megamonster runs constantly, circulating water from the sea at a rate of about 17,000 pounds per minute. That's like a small car's worth of water sloshing in every single second, all day, every day. The plumbing alone probably deserves its own postal code.

Why Would Anyone Build This Thing?

The genius — and let's be generous with that word — behind the pool is engineer Chilean Fernando Fischmann, who thought, "You know what people really want? A swimming experience that comes with the psychological uncertainty of drowning." Kidding, but only sort of. Fischmann's real gamble was that wealthy tourists would pay top dollar for the luxury of swimming in what is essentially a controlled, private beach.

Fischmann created a company called Crystal Lagoons, which now licenses this technology around the world. So technically, this massive pool in Chile was just the prototype, the Facebook of swimming pools. You're welcome, humanity.

The Benefits (and the Expense)

The pool offers beach-like experiences right next to resort hotels, which means you get ocean vibes without the jellyfish, riptides, or random seagull deciding your sandwich belongs to it. About 80% is required compared to a natural body of water, apparently, though "less maintenance" is relative when you're talking about a pool bigger than most neighborhoods. Someone still has to skim the leaves, and honestly, we feel sorry for that person.

Construction costs for pools like this run into the millions of dollars, which makes sense when you're essentially building a small inland sea. However, Fischmann's technology is surprisingly energy-efficient for its size, consuming only about 2% that a traditional pool of comparable scale would require. So it's an absurdly large pool that's only slightly absurd on the energy bill — we'll take it.
