Chalk Sound is a beautiful natural lagoon located on the southwest of Providenciales, an island belonging to the Turks and Caicos Islands, a British Overseas Territory in the North Atlantic Ocean. The waters of this 3-mile long lagoon is sparkling blue and studded with countless tiny rocky islands. While shallow bays with turquoise water are not unheard of but Chalk Sound is almost totally landlocked, which makes its dazzling electric-blue color all the more unbelievable. The water here is clean and algae free. Chalk Sound’s National Park status prevents the use of motorized watercraft in these waters which helps to maintain the pristine nature of the place.
