Geological Formation of the Chocolate Hills

The Origin of the Chocolate Hills

Have you ever wondered how the Chocolate Hills in Bohol were formed? The tale of their origin is as fascinating as it is ancient. Millions of years ago, during the Late Pliocene to Early Pleistocene epochs, tectonic activities began to shape what we now know as Bohol Island. These events set the stage for the creation of around 1,200 to 1,700 hills spread over an area of more than 50 square kilometers.

Coral Reefs and Limestone Formation

Interestingly, the Chocolate Hills owe much of their existence to coral reefs! These hills started as coral deposits that solidified into limestone over millions of years. Through a process known as uplift, movements in the Earth’s crust pushed these ancient coral reefs above sea level. Additionally, when you look at these hills today, you’re essentially looking at the remnants of ancient coral formations. Isn’t that mind-blowing?

Karst Landscape of Bohol Island

Bohol Island sits atop what’s considered a karst landscape, characterized by soluble rock such as limestone. Over time, water and natural erosive processes sculpted the limestone into the iconic conical shapes we see today. This mix of geological and erosive activities resulted in the unique natural beauty of the Chocolate Hills.
