The Corinth Canal, a man-made waterway cutting through the narrow Isthmus of Corinth, links the Gulf of Corinth with the Saronic Gulf in the Aegean Sea. Although completed in the late 19th century, the idea dates back to ancient times, when rulers like Periander and Julius Caesar considered its construction. It was finally realized under the guidance of Greek diplomat Ioannis Kapodistrias, with work beginning in the late 1880s.

Stretching around 6.4 kilometers in length and about 21.4 meters wide at its base, this canal is a stunning engineering feat. Its steep limestone walls, towering roughly 90 meters above the water, create a dramatic scene as ships navigate the narrow passage. Although too slim for large modern freighters, the canal hosts a mix of tourist boats, small cargo ships, and private yachts, offering travelers a unique glimpse into the area's geography and rich history.

The canal’s construction was no easy feat, marked by geological challenges and financial setbacks that caused the project to change hands several times before completion. Today, it’s more than just a shortcut, saving ships from a long journey around the Peloponnese peninsula—it’s a popular tourist attraction. Visitors are captivated by the canal’s impressive design and can even experience a thrill by bungee jumping from a bridge that spans the waterway, adding an adventurous touch to this historical marvel.
