The biggest swimming pool in the world
Located at the San Alfonso del Mar holiday complex, Chile, the swimming pool, designed by Crystal Lagoon steals the limelight from the Pacific Ocean. Measuring 1,013 metres in length, and three metres deep, it has been acknowledged by the Guinness Book of Records as the biggest swimming pool in the world. The intense turquoise of its water is achieved through a pressurised oxygen system, which purifies it while using hardly any chemical products.
