The Bohol Province of Phillipines is home a true natural wonder, popularly known as Chocolate Hills. The name may sound delicious, but this name is given due to the unique color and shape of the hills found in the region.
Chocolate Hills are groups hills spread across an area of around 50 square kilometer. These are perfectly shaped domes of short height, the highest being around 400 feet and the average is at 160 feet. It is hard to believe that these are natural structures but not man made landscape. The hills are beautifully covered with green grass during the rainy season and during dry season the grass get a brown color. These brown color hills look like cookies of chocolate and hence the name.
There is no unanimous geological explanation on these wonderful hills. The most widely accepted theory explains these conical karst hills as formations created ages ago by the uplift of coral deposits and the action of rain water and erosion. A recent theory explains that an ancient sub-oceanic volcano self-destructed and chunks of it were dispersed over the region.
The vegetation of the Chocolate Hills are is unique, covered with various hard grass species, ferns and compositae. It is also home to the unique primate species Tarsier. Unfortunately the flora and fauna of the Chocolate Hills are recently threatened by local querying.
