At over a kilometre long and covering 8 hectares, THIS MONSTER POOL at the San Alfonso Del Mar Resort in Chile is truly a site to behold.  It took 5 years to build at a cost of about $1.8 Billion, and costs over $3 Million per year to maintain.  The “deep end” is over 30 metres, and it holds 250 million litres of water.The pool uses a computer controlled suction and filtration system, drawing in from the ocean at one end and pumping it out the other.  The sun warms the water to 26 degrees celsius, 9 degrees warmer than the adjoining ocean.

Anyone up for some laps?
