Ilocos Region occupies the narrow plain between the Cordillera Central mountain range and the South China Sea. It also occupies the northern portion of the Central Luzon plain, to the northeast of the Zambales Mountains.
Lingayen Gulf is the most notable body of water in the region and it contains a number of islands, including the Hundred Islands National Park. To the north of the region is Luzon Strait.
Hundred Islands national park Located in the Lingayen Gulf in Pangasinan, the watery park is dotted by 123 small, pristine islands. Three islands have been developed for tourists.
Vigan colonial houses Vigan City is famous for its cobblestone streets and Spanish-style houses, an architectural remnant of its colonial past. The Mestizo District displays mansions typical of the era. They were owned by prominent Ilocano-Chinese merchant families of that time, hence mestizo or "mixed race."
Ancient churches The region is dotted by old Catholic churches built by natives for the Spanish. Famous churches can be found in Vigan City, once the seat of the Bishop of Nueva Segovia, and in Manaoag, Pangasinan.
