The Chocolate Hills (Cebuano: Mga Bungtod sa Tsokolate, Tagalog: Mga Tsokolateng Burol) are a geological formation in the Bohol province of the Philippines. There are at least 1,260 hills, but there may be as many as 1,776 hills spread over an area of more than 50 square kilometers (20 sq mi). They are covered in green grass that turns brown during the dry season, hence the name.
