Lefkada to Glicki Acheron River Gorge, Greece

This route bring you back in time, and nearly into Hades, if you're not careful. The Necromanteion (Oracle of the Dead) was an ancient Greek temple of necromancy devoted to Hades and Persephone. According to tradition, it was located on the banks of the Acheron river in Epirus, near the ancient city of Ephyra. This site was believed by devotees to be the door to Hades, the realm of the dead. The site is at the meeting point of the Acheron, Pyriphlegethon and Cocytus rivers, believed to flow through and water the kingdom of Hades. The Vikos Gorge, one of the deepest in the world, forms the centerpiece of the Vikos–Aoös National Park, known for its scenic beauty.
