San Alfonso del Mar is a resort located in Algarrobo, Chile frequently noted because of its 1,000-meter long, 19-acre outdoor pool, which holds a Guinness world record[1] as the largest in the world. 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.

Roughly equivalent to about 6,000 standard backyard pools, it took 5 years to build and cost nearly USD 2 billion and the annual maintenance is USD 4 million. Watch the video to feel what it’s like on the world largest pool. Check out the pictures below.
