Chocolate Hills

The unique karst landscape is composed of smooth, uniformly shaped conical isolated hills that cover a vast area (14,435 ha) in the central portion of the island. The site was once a platform of thick widespread buildup of coral reefs that thrived during the Pliocene, approximately 2-5 million years ago and later to form a sedimentary formation. Soon, this limestone formation was raised above the sea level and fractured. Rainwater, streams and groundwater dissolved the limestone, gradually forming the present landscape of cone karst.
