The Chocolate Hills are located in Bohol Province and is 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, spread over an area of more than 50 square km, these cone-shaped or dome-shaped hills are actually made of grass-covered limestone, that turns brown (like chocolate) during the dry season, hence the name. The domes vary in sizes from 30 to 50m high with the largest being 120m in height. They have been declared the country's third National Geological Monument and proposed for inclusion in the UNESCO World Heritage List in 2006, under the name Chocolate Hills Natural Monument.
