Punakaiki is best known for its Pancake Rocks and Blowholes both of which are spectacular and a must-see when visiting the West Coast. Nature began this work of art about 30 million years ago. Over thousands of years, alternating layers of small marine creatures and sand became buried and compressed on the ocean floor. This created areas with multiple layers of hard limestone and softer sandstone. Earthquake activity then lifted the ocean floor high and dry, and those slow motion artists - the rain and the wind - began to erode the softer sandstone. The outcome is cliffs and ravines with hundreds of horizontal slices along their vertical faces, like huge stacks of pancakes.
