The Chocolate Hills Natural Geological Monument is an unusual geological formation in Bohol Province, Philippines. 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 Chocolate Hills form a rolling terrain of haycock hills – mounds of a generally conical and almost symmetrical shape. 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. 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.
