The Vikos Gorge (Greek: Φαράγγι του Βίκου) is a gorge in the Pindus Mountains of northern Greece. It lies on the southern slopes of Mount Tymfi, with a length of about 20 km, depth ranging from 120 to 490 m and a width ranging from 400 m only a few metres at its narrowest part. Vikos is listed as the deepest gorge in the world by the Guinness Book of Records among others. This follows a somewhat arbitrary definition of a gorge that excludes deeper features such as Colca Canyon because of their greater width:depth ratio The gorge is found in the core zone of the Vikos–Aoös National Park, in the Zagori region. It begins between the villages of Monodendri and Koukouli and ends near the village of Vikos (or Vitsiko). The gorge collects the waters of a number of small rivers and leads them into the Voidomatis River which forms in the gorge. The major part of Voidomatis is only seasonal, and is permanent only at the lowest part of the gorge. Vikos is also a site of major scientific interest, because it is in almost virgin condition, it is a haven for endangered species and contains many and varied ecosystems.
