The Corinth Canal cuts through the Isthmus of Corinth, turning the Peloponnese into an island as it separates the region from the Greek mainland. Inaugurated in 1893, the canal is a little over six kilometres long and enables merchant vessels and passenger to avoid a long 400-km detour around the peninsula. The two sides of the canal reach a height of approximately fifty metres. From the exterior decks, don’t miss this unique opportunity to watch the ship as it navigates along the narrow strip of water encased between tall, ochre cliffs. What an experience!
