Cagayan Valley

Cagayan Valley (Filipino: Lambak ng Cagayan, Ibanag: Tana' nak Cagayan, Ilokano: Tanap ti Cagayan, Itawis: Tanap yo Cagayan, Malaueg: Ga-dang yo Cagayan) (designated as Region II or Region 02) is an administrative region in the Philippines located in the northeastern portion of Luzon. It is composed of five provinces: Batanes, Cagayan, Isabela, Nueva Vizcaya, and Quirino. The region has four cities: industrial center Cauayan, its regional center Tuguegarao, its primary growth center and investment hub Ilagan and its premier city Santiago.

Most of the region lies in a large valley in northeastern Luzon, between the Cordilleras and the Sierra Madre mountain ranges. The eponymous Cagayan River, the country's longest, runs through its center and flows out from its source in the Caraballo Mountains in the south to the Luzon Strait in the north, in the town of Aparri, Cagayan. The Babuyan and Batanes island groups that lie in the Luzon Strait belong to the region.

Cagayan Valley is the second largest region of the Philippines in terms of land area.

Cagayan

Cagayan (/kɑːɡəˈjɑːn/ kah-gə-YAHN) is a province of the Philippines in the Cagayan Valley region in the northeast of Luzon Island, and includes the Babuyan Islands to the north. The province borders Ilocos Norte and Apayao to the west, and Kalinga and Isabela to the south. Its capital is Tuguegarao.

Cagayan was one of the early provincias that existed during the Spanish Colonial Period. Called La Provincia de Cagayan, its borders essentially covered the entire Cagayan Valley, which included the present provinces of Isabela, Quirino, Nueva Vizcaya, Batanes and portions of Kalinga and Apayao. The former capital was Nueva Segovia, which also served as the seat of the Diocese of Nueva Segovia. Today, only 9,002.70 square kilometers remain of the former vastness of the province. The entire region, however, is still referred to as Cagayan Valley. In 2013, Cagayan was host to the 27th (Survivor: Blood vs. Water) and 28th (Survivor: Cagayan) seasons of the reality television series Survivor (U.S. TV series).
