Sierra Madre

The Sierra Madre is the longest mountain range in the Philippines. Running in the north-south direction from the provinces of Cagayan to the north and Quezon to the south, the mountains form the eastern backbone of Luzon Island, the largest island of the archipelago. It is bordered by the Pacific Ocean to the east. The Pacific coast of Luzon along the Sierra Madre is less developed as the lofty and continuous mountains forms a bold and an almost inaccessible shore, exposed to the full force of the northeast monsoon and the waves of the Pacific Ocean. Some of communities east of the mountain range and along the coast are so remote they are only accessible by plane or boat.The country's largest protected area, the Northern Sierra Madre Natural Park, is situated at the northern part of the range in the province of Isabela.GeographyThe Sierra Madre is the longest mountain range in the Philippines. In the north, the range starts in the province of Cagayan and ends in the south in the province of Quezon. In the province of Nueva Vizcaya, the Caraballo Mountains connect Sierra Madre Mountain range with the Cordillera Central range.
