2015's Top 27 Clearest Waters

Bonito, Mato Grosso do Sul in Brazil

Due to the large quantity of limestone in the ground, the water of these rivers runs through a natural filter and impurities fall to the bottom of the river. This makes the Bonito rivers the clearest and most transparent in the world.  Things don't get anymore pristine and relaxing than this.

Aitutaki in Cook Islands

This place looks like something that came out of a movie.  Perhaps it was the inspiration for the Brooke Shields starrer, "The Blue Lagoon?"  Without a doubt, this is the most gorgeous Polynesian lagoon on the planet!
