Chocolate Hills of Bohol Philippines

The Chocolate Hills are located on the Island of Bohol. They are over 1,200 hills, covering over 50 km² and get their name because the grass which covers the hills turns brown during the dry season. The hills are almost all conical in shape and made of limestone. Many people have believed that they were human creations. Geologists are not entirely sure how they were created. Theories include erosion of limestone, volcanic uplift, and accretion of limestone around basalt fragments from a volcanic eruption. The government of the Philippines has declared it one of their flagship tourist destinations. The Chocolate Hills are so central to the people of Bohol, they appear on the flag of the province.
