Acheron river

The Acheron River, one of the most mystical rivers in the Balkans, is located in the Epirus region in northwestern Greece and is known for its exceptionally cold, clear water that springs from the Tomaros mountain massif in the region of Souli. In ancient times, it was considered one of the mythical crossings to the underworld, surrounded by stories about Hades and the souls that cross the boundary of the worlds. Today, it represents a blend of scientific and mythological interest—a unique ecosystem in a dramatic canyon.
