It is the second-largest administrative region in the Philippines by land area. The land sits in a wide valley between big mountain ranges. To the west, you will find the Cordillera mountains. To the east, the Sierra Madre mountains stretch out. The Caraballo Mountains sit to the south of the valley.

To the north, the region meets the Luzon Strait.

A very important feature of this place is the Cagayan River. This river is the longest and largest in the whole country. It starts in the Caraballo Mountains and flows through the valley. The water eventually ends its journey at a place called Aparri.

The region is made of five different provinces. These are Batanes, Cagayan, Isabela, Nueva Vizcaya, and Quirino. Two of these provinces, Quirino and Nueva Vizcaya, are landlocked. This means they are surrounded by land and have no coast. These areas are often very rugged with many trees and hills.

The history of this land involves many different groups of people. Long ago, the first people here were known as the Atta or Negritos. Later, other groups like the Ibanags and Itawes arrived. During the Spanish era, the area was much larger than it is now. It was once called Provincia de Cagayan. The Spanish used the Ibanag language to help people communicate. Over time, many other groups moved here too. These included Ilocanos, Tagalogs, and even people from China and India.

Many things have shaped how the region works today. In the past, many Ilocano people moved here to grow tobacco. Tobacco is still a very important part of the local economy. The region also has four main cities. These are Cauayan, Ilagan, Santiago, and Tuguegarao. Tuguegarao is the largest city and serves as the regional center.

A literacy survey in 2019 showed that 93% of citizens can read and write. This makes the region 5th out of the 17 regions in the Philippines.

Life in the valley can change with the weather. In November 2020, a big storm called Typhoon Ulysses hit the area. This caused the Magat Dam to release a lot of water. The extra water flowed into the Cagayan River and caused big floods.

These floods affected many people in Cagayan and Isabela. The region also faced the COVID-19 pandemic starting in March 2020. The first case was found in the city of Tuguegarao. Even with these challenges, the people of the valley continue to live and work in this unique landscape.
