Chocolate Hills
Visayas Region
The Chocolate Hills are a remarkable natural geological formation located in the province of Bohol in the Philippines. This landscape consists of at least 1,260 to possibly 1,776 nearly symmetrical, conical hills spread over more than 50 square kilometers. The hills are covered with green grass that turns chocolate-brown during the dry season, giving the formation its iconic name. These dome-shaped mounds range from 30 to 50 meters in height, with some reaching up to 120 meters. The hills are composed of marine limestone dating back to the Late Pliocene to Early Pleistocene epochs and contain abundant marine fossils. Their formation is attributed to a combination of limestone dissolution by rainfall and groundwater, as well as erosion following tectonic uplift, classifying them as conical karst or cockpit karst formations. The Chocolate Hills are a symbol of Bohol's natural heritage, featured on the provincial flag and seal. Two main viewing points, the Chocolate Hills Complex in Carmen and Sagbayan Peak, provide panoramic vistas of this extraordinary landscape. The area is protected as a National Geological Monument and is proposed for UNESCO World Heritage status. Despite various myths about their origin, scientific evidence supports the karst formation process without volcanic activity involvement. The hills' natural vegetation is dominated by grasses and ferns, though quarrying poses a threat to their preservation.

History
The Chocolate Hills' geological formation dates back to the Late Pliocene to Early Pleistocene periods, formed through natural processes involving limestone dissolution and erosion after tectonic uplift.
Recognized for their unique characteristics and scientific importance, they were declared a National Geological Monument in 1988.
Further protection was established in 1997 under a presidential proclamation, designating the hills and surrounding areas as a natural monument to preserve their beauty and prevent exploitation.
Over time, the site has become a significant symbol of Bohol's natural heritage and a major tourist attraction.
