The Chocolate Hills is an unusual geological formation in Bohol province, Philippines. There are at least 1,260 hills but there may be as much 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 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 have been declared the country’s third National Geological Monument and proposed for inclusion in the UNESCO World Heritage List.
The Chocolate Hills form a rolling terrain of haycock hills – mounds of a generally conical and almost symmetrical shape. Estimated to be from 1,268 to about 1,776 individual mounds, these cone-shaped or dome-shaped hills are actually made of grass-covered limestone. The domes vary in sizes from 30 to 50 metres (98 to 160 ft) high with the largest being 120 metres (390 ft) in height. Bohol’s “main attraction”, these unique mound-shaped hills are scattered by the hundreds throughout the towns of Carmen, Batuan and Sagbayan in Bohol.
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.
