Turks & Caicos: : Chalk Sound National Park
If you are not sure what “turquoise” color is like – you need to visit this little national park (and if you can’t spell “turquoise” you have bigger issues). This is really just a small lagoon, 3 miles long, studded with tiny uninhabited islets. But the color is insane – bright and fluorescent turquoise! The park only protects the lagoon’s water, the shore is covered with housing. So it’s almost impossible to get a good picture or even approach without some minor private property trespassing.
