San Alfonso del Mar, a luxury resort in Chile, boasts the largest swimming pool in the world, and we’re not just talking “it can fit the whole family and then some” big. The Crystal Lagoon is so big, you can literally sail a boat from one end to the other. Yeah, that big.
The saltwater pool contains 66 million (!) gallons of crystal-clear, filtered seawater and is 3,323 feet long. That’s equivalent to lining up 20 Olympic-size pools in a row. But be careful if you wander into the deep end; while you might be able to see all the way to the bottom, at its deepest, the pool floor is 115 feet down.
