The eastern two-thirds of a divided island
The Dominican Republic occupies roughly the eastern two-thirds of Hispaniola, the second largest island in the Caribbean. It shares a 376-kilometer border with Haiti to the west. The Cordillera Central runs through the center of the country, containing Pico Duarte at 3,098 meters, the highest point in the entire Caribbean. That mountainous interior gives way to fertile valleys, coastal plains, and a tourism-oriented eastern coastline.
