Along its path it converges with other streams originating from the banks of Tymfi or the Vikos Gorge.

[citation needed] The Voidomatis has been characterized as one of the cleanest rivers in Europe as it does not face any environmental issues.

It crosses one of the most beautiful natural locations in Greece and has been part of the Vikos–Aoös National Park since 1973.

Archaeological excavations were undertaken at Kleidi Cave just above the Voidomatis by a British team between 1983 and 1986.

The excavations revealed the cave that contained artefacts, stone tools, faunal remains and other fossils, that were dated back to the Palaeolithic and the Epigravettian culture between 20,000 and 12,000 years ago.
