The Corinth Canal connects the Gulf of Corinth in the Ionian Sea with the Saronic Gulf in the Aegean Sea.
It cuts through the narrow Isthmus of Corinth and separates the Peloponnese (a peninsular region in southern Greece) from the Greek mainland.
It is at sea level and has no locks. It is 4 miles long and 80 feet wide making it impassable for many modern ships.
Our photos show how close our ship was to the sides of the canal.
