The Chocolate Hills are an unusual geological formation that is one of the most important sights of the Philippine island of Bohol. In total, the formation includes 1268 almost perfectly hemispherical or conical hills of about the same height and dimensions, spread over an area of more than 50 km². They are all covered only with green grass, which turns brown during the dry season and gives the hills their name. As the most famous tourist attraction of Bohol, the Chocolate Hills are depicted on both the flag and the seal of the island province and generally represent the natural attractions that Bohol has to offer. They are on the one hand on the official list of tourist destinations in the Philippines, the Philippine Tourism Authority’s List, and have also been named the country’s third National Geological Monument. They are also proposed for inclusion in the UNESCO World Heritage List. Wikipedia
