Cagayan is the Regional Seat of the Cagayan Valley Region.
Tuguegarao City, the capital, is the seat of commerce and trade and center for learning. The province has 73 percent of the region's potential fishing area.
Known as the spelunker's, trekker's, and gamefisher's paradise rolled into one, Cagayan provides a never-ending adventure with ecotourism in the forefront of its offering. Both foreign and local tourists continue to explore its caves, engage in gamefishing expeditions, trek its mighty mountains and retreat to its centuries-old churches.
Present day chroniclers say that the name was derived from the word "tagay," a kind of plant that grows abundantly in the northern part of the province. Thus, "Catagayan" which means a place where the tagay grows abundantly was shortened to "Cagayan," the present name of the province.
