If you tend to take a couple of laps of the pool before work, you may have to get up extra early.
The San Alfonso del Mar pool is over a thousand yards long and holds 66 million gallons
The Guinness Book of Records has named a 20-acre swimming pool in the Chilean resort of San Alfonso del Mar as the largest in the world. A hundred and fifteen feet deep at its deepest and a thousand yards long, the 20-acre leviathan holds 66 million gallons of water and is navigable in small boats.
It is a hundred and fifteen feet deep at its deepest, and cost almost £1 billion to make
The pool, near Algarrobo on the south coast of the South American country, opened last month after a building project lasting five years and costing almost £1 billion. It has become an instant tourist magnet, with thousands of people flocking to see it.
The vast lido requires high-technology filtration systems to keep the water fresh, with a computer-controlled system drawing in water from the sea from one end and pumping it out of the other.
Fernando Fischmann, developer of the “pulse oxidation” technology used in the pool, says that that pumping the water back in to the ocean does no harm to wildlife or ecosystems.
Crystal Lagoons, Fischmann’s company, is believed to be planning as many as six more mega-pools for locations in Panama, Argentina and, predictably, Dubai.
