One of the top tourist attractions in the Philippines, The Chocolate Hills are unusual geological formations that consists of at least 1,268 individual mounds scattered throughout the interior of the island of Bohol.
The almost symmetrical and same-sized formations range from 98 to 164 feet (30 to 50 meters) high and are covered in green grass. During the dry season the grass turns brow, hence the name.
There is no consensus on how these giant mole hills were formed. One theory holds that the Chocolate Hills are the weathered rock formations of a kind of marine limestone on top of an impermeable layer of clay.
