Best known for tourist spots such as Vigan City, the Paoay Church, Urbiztondo Beach, and the Hundred Islands National Park. Of these four attractions, Vigan City and the Paoay Church have been recognized as UNESCO World Heritage Sites.

As a region consisting of four provinces, the locals speak in different languages depending on where they live. However, the most popular languages are Ilocano, Pangasinan, and Tagalog.

Another important aspect of the region is religion as it has contributed heavily to the culture and even architecture of Ilocos. The majority of the residents subscribe to the Roman Catholic faith like most of the Filipino population. This is largely seen through the various churches built in the provinces, such as the historic Paoay Church in Ilocos Norte.
