The Chalk Sound National Park is a beautiful natural lagoon located southwest of Providenciales. This national park is known for its shallow, brilliant turquoise water and hundreds of small rocky islands.
Although Chalk Sound is nearly landlocked, a winding channel connects it to the ocean and the Caicos Banks south of Providenciales.
Powered watercraft are not permitted on Chalk Sound due to its protected status as a national park. Most visitors come to see the southern side of the island for sightseeing or as a kayaking and paddle boarding destination.
Chalk Sound’s water is clear and free of algae. The incredible turquoise hues are caused by the refraction of sunlight off the area’s fine limestone sand and particles.
Chalk Sound is also the name of the Chalk Sound residential area.
