Ilocos Coastal Plain
This is a narrow strip of land facing the west Philippine sea (formerly called china sea) at the western side of northern Luzon. The mountain systems and hills lie close to the sea. Sand dunes, which are hills or ridges of sand piled up by the wind, are characteristics features of the sandy coastal plain.
Central Cordillera
This is a mountain region stretching from Kalinga to Benguet. Its highest point is 3000 meters above sea level.
Cagayan Valley
This lies between the central cordillera and the Sierra Madre mountains. This valley is drained by the Cagayan river.
Eastern Cordillera, also called the Sierra Mountains
This is the longest mountain system of the country at the eastern side of Luzon facing the Pacific ocean. It covers the provinces of Cagayan, Isabela, Nueva Viscaya, Nueva Ecija, Aurora, and Quezon. Its highest point is 2000 meters sea level.
