Travel past the rocky coves of the Saronic Gulf to Isthmia where you board a motorlaunch for a transit of the Corinth Canal. This 19th-century engineering marvel cuts through sheer rock, dividing the narrow causeway that links the Peloponnesus with the Greek mainland. Carved into a massive rock, the 76-foot wide and 26-foot deep canal dramatically separates the Peloponnese from the rest of mainland Greece. Before the Corinth Canal was constructed, ships had to sail all the way around the Peloponnese, adding 185 nautical miles and several extra days to the journey. A fantastic photo opportunity can be had 200 feet above water, from the center of the bridge that spans its banks. Then embark a motorlaunch in Isthmia for an exciting 45 minute cruise through the canal which dramatically separates mainland Greece from the Peloponnese thus creating the largest man-made island in Europe.
