19 bluest waters in the world

The most popular colour in the world is blue, so it’s no surprise that people flock to the turquoise beaches of the Caribbean or the sapphire hot baths of Iceland. Many factors affect the exact colour of water—sediment and nutrients can make it appear murky, while nearby coral reefs can keep water clear—but the tint comes from blue wavelengths of light absorbed from the sun.

If you’re looking to take in some cool shades while lounging in the surf, here are some destinations worth a trip.
