The old-growth forest of Fraktos, situated in the northeastern part of the Prefecture of Dramas in northern Greece under the highest summit of central Rhodope Mountains with an altitude of 1,953 meters, is the only Virgin Forest in the country and among the most unique in Europe.The Fraktos Forest had been declared a military zone for years and grew following only the rules of nature due to the fact that no humans had intervened. The human presence was limited to such a degree that the forest ecosystem was unaffected for at least 500 years.

The woodland was registered as a virgin forest in 1979 and a year later was declared protected monument of nature.

The Fraktos Forest fauna is home to 100 species of birds and 32 species of mammals including all rare animal species in Greece and Europe.
