The Cagayan River, also known as the Rio Grande de Cagayan, is the longest and largest river in the Philippine archipelago. It originates in the Caraballo Mountains and flows north for approximately 505 kilometers, draining a massive basin of about 27,753 square kilometers. The river traverses the vast Cagayan Valley, a fertile agricultural region situated between the Sierra Madre and Cordillera Central mountain ranges. Its extensive watershed supports the livelihoods of millions, primarily through agriculture, with rice, corn, and tobacco being major crops. The river is also a vital source for fishing. Its powerful current and tendency to flood during the typhoon season present both opportunities and challenges for the region. The Cagayan River and its numerous tributaries create a complex and dynamic river system that has shaped the landscape and culture of Northern Luzon.
