You may have seen this floating around the internet, pardon the pun. I thought it was fairly impressive and so decided to include it here almost word for word. So, my thanks to the original author.
If you like doing laps in the swimming pool, you might want to stock up on the energy drinks before diving into this one. It is more than 1,000 yards long, covers 20 acres, had a 115ft deep end and holds 66 million gallons of water.
The Guinness Book of Records named the vast pool beside the sea in Chile as the biggest in the world by ‘area’.
If you fancy splashing out on one of your own – and you have the space to accommodate it – then beware: This one took five years to build, cost nearly 1billion and the annual maintenance bill will be 2million.
The man-made saltwater lagoon has been attracting huge crowds to the San Alfonso del Mar resort at Algarrobo, on Chile ‘s southern coast, since it opened last month.
Its turquoise waters are so crystal clear that you can see the bottom even in the deep end.
It dwarfs the world’s second biggest pool, the Orthlieb – nicknamed the Big Splash – in Morocco , which is a mere 150 yards long and 100 yards wide. An Olympic size pool measures some 50 yards by 25 yards.

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.’

All I can say is WOW!

You would be forgiven for thinking you were in Miami or Dubai, while you floated along on your blow-up mattress from one end to the other. I wonder if that is real grass or astro-turf?
