Chocolate Hills

The Chocolate Hills (Cebuano: Mga Bungtod sa Tsokolate, Filipino: Mga Tsokolateng Burol, or Mga Burol na Tsokolate) are a geological formation in the Philippine province of Bohol. There is a minimum of 1,260 hills and possibly up to 1,776, spread over an area of more than 50 square kilometers (20 sq mi). They are covered in green grass that turns a chocolate-brown during the dry season, hence the name.

These conical hills are geomorphological features called cockpit karst, which were created by a combination of the dissolution of limestone by rainfall, surface water, and groundwater, and their subaerial erosion by streams after they had been uplifted above sea level and fractured by tectonic processes.
