Kapurpurawan Rock Formation is another must-see attraction in Ilocos Norte. It is a natural wonder formed by the forces of wind and water over thousands of years. The white limestone rocks stand out against the blue sky and the turquoise waters of the West Philippine Sea. You can take a leisurely walk around the rock formation and marvel at its unique shapes and textures. The area is also a great spot for photography, especially during sunrise or sunset when the golden light enhances the beauty of the rocks.
