If you want to take a dip in the world’s largest swimming pool, you’ll have to travel to San Alfonso del Mar resort in Algarrobo, on Chile’s southern coast. Acknowledged by the Guinness Book of World Records as the world’s largest swimming pool, the man-made saltwater lagoon has been attracting huge crowds since it opened. It is 1,013 meters long, covers an area of 20 acres, had a deepest end of 115 feet and holds 66 million gallons of water. The world’s largest swimming pool took five years to build, costing nearly $2 billion and an annual maintenance bill of $4 million.

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. Its turquoise waters are so crystal clear that you can see the bottom even in the deep end. 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.”
