North Caicos is the second-largest island in the Turks and Caicos Islands (after Middle Caicos). To the west, the Caicos Cays (the closest is Parrot Cay) link to Providenciales. To the east, it is separated from Middle Caicos by Juniper Hole, a narrow passage that can accommodate only small boats. A 1-mile causeway connects North Caicos to Middle Caicos.
