The Chocolate Hills is a geological formation in Bohol Province, Philippines. There are at least 1,260 hills but there may be as many as 1,776 hills spread over an area of more than 50 square kilometres (20 sq mi). They are covered in green grass that turns brown (like chocolate) during the dry season, hence the name.
The Chocolate Hills is a famous tourist attraction of Bohol. They are featured in the provincial flag and seal to symbolize the abundance of natural attractions in the province. They are in the Philippine Tourism Authority's list of tourist destinations in the Philippines; they have been declared the country's third National Geological Monument and proposed for inclusion in the UNESCO World Heritage List.
During the dry season, the grass-covered hills dry up and turn chocolate brown. This transforms the area into seemingly endless rows of "chocolate kisses". The branded confection is the inspiration behind the name, Chocolate Hills.
The vegetation of the Chocolate Hills is dominated by grass species such as Imperata cylindrica and Saccharum spontaneum. Several Compositae and ferns also grow on them. In between the hills, the flat lands are cultivated with rice and other cash crops. However, the natural vegetation on the Chocolate Hills is now threatened by quarrying activities.
The most famous and signature tourist attraction of Bohol, it is a prime tourist destination in the Philippines. The national government has chosen the Chocolate Hills as one of its "flagship tourist destinations".
Of the 1,247 hills, two have been developed into resorts for tourism. The original resort is located in Carmen, Bohol located in Barangay Buenos Aires, only a few minutes drive from downtown Carmen. The resort in Carmen is called Chocolate Hills Complex. The more recent one in Sagbayan is called Sagbayan Peak.
