San Alfonso del Mar is a resort located in the central coast of Chile, frequently noted because of its 1,000-meter long, 19-acre outdoor pool, which holds a Guinness world record. The resort’s large pool utilizes a technology developed by the Chilean company Crystal Lagoons, which uses water pumped from the Pacific Ocean, that is then filtered and treated for supply to the pool.
