Sierra de Samaná hills

The Cordillera Septentrional is a mountain range that runs parallel to the north coast of the Dominican Republic, with extensions to the northwest as Tortuga island in Haiti, and to the southeast through lowlands to where it rises as the Sierra de Samaná on the Samaná Peninsula.

The Sierra de Samaná stretches along the Samaná peninsula, over a length of 60 kilometers. The peninsula's highest points are: La Meseta at 650 meters, Las Cañitas at 546 meters and Pan de Azúcar at 493 meters.

This mountain range contains deposits of marble and lignite, but only the marble has been mined.
