It is unknown how many chocolate hills there are. It is known that at the bare minimum there are 1268 hills but some estimates put this number as high as 1776.The hills are not huge; the highest one barely reaches 120 meters in height. Even so, most hills are between 30 and 50 meters. The conical Chocolate hills are scattered within a fifty square kilometer area.

 

 

Mystery still surrounds how the Chocolate Hills were formed. One of the more popular local legends is that long ago, two giants fought for days, hurling earth and stones at one another, until they fell exhausted, friends once more, into each other's arms.

 

However geologists have differing views about how these hills were formed. One plausible theory is that they are weathered formations of a marine limestone lying on top of an impenetrable clay base.

 

At the end of the dry season, the famous hills earn their name when the grass turns from green to brown. At all times, they retain a uniform look as, curiously, no trees or clumps of shrubs will grow on them.
