Silky, powder-white sand seems to get all the attention these days—but what good is perfect sand without crystal-clear water to match? Check out the full list here:
  1. Bonito, Brazil

    Thanks to the high concentration of underground limestone—which acts as a natural filter—the rivers surrounding the Brazilian municipality of Bonito are exceptionally clear and vividly blue. (So blue that the region has been dubbed “Caribe do Centro-Oeste,” the Caribbean of the Central-West). Rio da Prata is one of the most dramatically blue rivers in the region, and is popular with snorkelers thanks to its water clarity and plentiful marine life. Photo Courtesy: Alamy
  2. Lampedusa, Sicily, Italy

    Lampedusa is the largest and most stunning of the Italian Pelagie islands in the Mediterranean Sea, and so far south that it’s actually closer to Tunisia than mainland Italy. All of those are very valid reasons to pay a visit—but what you’re really here for is that famous water: shimmering, crystalline, and electric-blue. Rabbit Beach is the island’s most popular swimming spot, offering blissful shallows to splash around in, framed by gently sloping limestone cliffs. Photo Courtesy: Getty
  3. Maldives

    A roundup of the world’s bluest waters would be incomplete without the Maldives, home of turquoise-blue waters so vibrant they seem surreal. In fact, Maldivian waters are so translucent, it often appears as if the boats sailing around the islands are floating in mid-air. Photo Courtesy: Getty
  4. Navagio Bay, Zakynthos, Greece

    It seems as if all the Greek islands are framed by that killer shade of emerald blue, but there’s something about the waters at Navagio Bay on the tiny island of Zakynthos that makes your heart skip a beat. Perhaps its the sheer seclusion and protected location (it’s sheltered on either side by soaring cliffs) that keeps its aquamarine waters so perfect and pure. Photo Courtesy: Getty
  5. Exuma, Bahamas

    The waters that surround Exuma's 365 islands are so supernaturally blue and clear it feels as if you’re in an infinity pool, whether you’re swimming alongside adorable piglets on Big Major Cay or wading in the calm shallows of Small Hope Bay. Beautiful hue aside, Bahamian waters are calm and warm all year round—rarely dipping below 72 degrees Fahrenheit—which means you can swim comfortably even in the cooler winter months (December through February).
