Crystal Lagoon is the largest pool in the world. It is found in San Alfonso del Mar resort, Chile. It is the largest pool in the world according to the Guinness Book of Records, with no less than eight hectares (1 hectare ~ 2.4 acres) of clear water and perfect sand, all on one kilometer long (.65 miles).
As a huge fan of pools, I personally think this is so cool! What do you guys think about this? Let us know in your comments!
