A Spectacular Lagoon

The most emblematic building work at San Alfonso holds the current Guinness record as the world’s largest crystalline water pool, with an extension of more than one kilometer in length, eight hectares and 250 million liters of water. Hard to imagine? We are talking about nothing less than the equivalent to 6,000 familiar 8-meters-long pools. 

Apart from its large size, the lagoon has another spectacular feature: its waters have the transparency and intense turquoise color of tropical seas. This has been made possible thanks to an advanced technology* developed by the company Crystal Lagoons, which is able to collect ocean water and keep it in perfect condition. But this is not all that it is there: during summer, the lagoon further maintains a pleasant temperature that borders 26ºC, nine degrees more than the nearby sea temperature. The success and exclusivity of this technology has enabled Crystal Lagoons to export its know-how to major international real-estate projects. 

In this way, at San Alfonso an unbelievable goal is achieved: feeling the enjoyment of the Caribbean Sea right at the Chilean central coast.
