Try making a splash in the world's largest swimming pool... it's 1,000 yards long

If you like doing laps in the swimming pool,

you might want to stock up on the energy

drinks before diving in to 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.

Yesterday the Guinness

Book of Records named the vast pool beside

the sea in Chile as the biggest in the world.

But 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 Olympicsize

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."
