Firstly we will start by crossing the highway and stop at the Canal (Isthmus) of Corinth. The Isthmus of Corinth is a narrow strip of land that connects mainland Greece to Peloponnese,
while the canal drilled across it connects the Saronic with the Corinthian Gulf, thus connecting the Aegean Sea with the Ionian Sea. The length of of the Isthmus is about 6 kilometers and the narrowest point is where the Corinth Canal has been drilled (1880 to 1893).
