I will go to Epirus on December, so I will return with more postcards!!
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, an altitude that ranges from 450 m to 1.600 m and a width from 400 m to some meters 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. [wikipedia]
