The Chocolate Hills are a group of unusually shaped hills located in the middle of the island of Bohol in Philippines. The Chocolate Hills are thought to have been formed as uplifted marine limestone was cracked by tectonic movements and then weathered away by water and wind. More than 1,300 individual hills cover more than 50 square kilometres and range from 30 to 90 metres in height.This extraordinary landscape is unique to this small island.
