Meet the San Alfonso del Mar resort in Chile, it features the world?s largest luxury swimming pool!

Awarded the Guinness World Record for largest outdoor pool in the world, the San Alfonso?s most popular amenity stretches almost 20 acres and holds up to 250 million litres of water!

Thanks to green technology, the water gets pumped from the Pacific Ocean and is then filtered and treated to get rid of all of the salt. The result is a transparent and beautifully turquoise coloured body of water.
