The Chocolate Hills is an unusual geological formation in Bohol, Philippines. It is composed of around 1,268 perfectly cone-shaped hills of about the same size, 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. It is featured in the provincial flag and seal to symbolize the abundance of natural attraction in the province. It is in the Philippine Tourism Authority's list of tourist destinations in the Philippines; it has been declared the country's 3rd National Geological Monument and proposed for inclusion in the UNESCO World Heritage List.
The Chocolate Hills and the area around it have relatively flat to rolling topography with elevation ranges from 100 to 500 metres (330 to 1,600 ft) above sea level. Higher karstic hills dominate the landscape inland then turning almost uniformly and naturally molded in Carmen.
Three legends explain the formation of the Chocolate Hills. The first tells the story of two feuding giants who hurled rocks, boulders and sand at each other. The fighting lasted for days, and exhausted the two giants. In their exhaustion, they forgot about their feud and became friends, but when they left they forgot to clean up the mess they had made during their battle, hence the Chocolate Hills.
A more romantic legend tells of a giant named Arogo who was extremely powerful and youthful. Arogo fell in love with Aloya who was a simple mortal. Aloya's death caused Arogo much pain and misery, and in his sorrow he could not stop crying. When his tears dried the Chocolate Hills were formed.
The third legend tells of a town being plagued by a giant carabao, who ate all of their crops. Finally having had enough, the townsfolk took all of their spoiled food and placed it in such a way that the carabao would not miss it. Sure enough, the carabao ate it, but his stomach couldn't handle the spoiled food, so he defecated, leaving behind him a mound of feces, until he had emptied his stomach of the food. The feces then dried, forming the Chocolate Hills.
