Located in the heart of the island of Bohol in the Philippines, the Chocolate Hills—in the right season—might remind you of Charlie and the Chocolate Factory. This geological formation, composed of over 1,200 perfectly cone-shaped hills, has long been a source of intrigue and fascination for travellers.
Aptly named after the colour they take on during the dry season, these geological wonders transform into a stunning shade of chocolate brown—a rather surreal sight.

The Geological History and Phenomenon
The formation of the Chocolate Hills dates back millions of years to the late Pliocene to the early Pleistocene epoch. These natural wonders were created through a complex process of uplift and erosion. Scientists believe the hills were originally underwater limestone deposits that emerged due to tectonic movements and the upward thrust of the Earth's crust.
Following their emergence, weathering and erosion sculpted the limestone formations into the cone-shaped hills we see today. The persistent action of rainwater eroded the soft limestone over time, resulting in these unusual and symmetrical mounds. As the rainwater washed away the surface soil and vegetation, the exposed limestone rocks turned brown during the dry season, giving rise to the name "Chocolate Hills."
Similar Hills Around the World
While the Chocolate Hills of Bohol are undoubtedly unique, similar strange hills can be found in various parts of the world. For instance, the Biri Rock Formations in the Philippines and the Tsingy de Bemaraha in Madagascar share similarities with the Chocolate Hills. Both feature dramatic limestone landscapes shaped by erosion over the ages, presenting a spectacle that captivates the imagination.
When to Visit
The Chocolate Hills are open to visitors year-round, but the best time to witness their striking chocolate hue is during the dry season, which typically lasts from late November to April. Travellers from all corners of the globe venture to Bohol to witness this natural marvel up close.
The Philippine government has taken great care in preserving and protecting this natural treasure. Accessible viewing points and well-maintained walking trails ensure that tourists can enjoy the Chocolate Hills's beauty while minimising the fragile ecosystem's impact.
How to Reach
Bohol is easily accessible by air, with several daily flights connecting the island to the major cities of the Philippines, including Manila and Cebu. The Bohol-Panglao International Airport serves as the primary gateway to the island, providing travellers with a convenient starting point for their journey to the Chocolate Hills and other attractions in the region.
