The Corinth Canal has been a long anticipated dream for the Greeks, who struggled to come up with a way to separate Peloponnese from the rest of the mainland ever since antiquity. Due to the high cost and the lack of means back in the days, the dream of Corinth Canal was abandoned till 1830, when Greece became independent again and could start making plans for financial prosperity. 
Finally, the Corinth Canal was built in 1893 and made it possible for the narrow Isthmus of Corinth to separate Peloponnese from the Greek mainland. The Gulf of Corinth is connected with the Saronic Gulf in this very spot. However, the narrowness of the site makes it impossible for large ships to pass through it without risking damage. So the canal has not been used as much as it had been expected. In fact, nowadays there is significant traffic in the canal but mostly by tourists. 

It is worth noting that the Corinth Canal is only 6.4 kilometers long and 21.4 meters wide, whereas the excavations have been made at sea level. This explains why there are no locks there on site, but it also explains why larger ships cannot use the canal. 
Anyone interested in watching this engineering spectacle from up close is welcome to access the Corinth Canal and get on board. Seeing these strips of land divided as you are afloat makes your heart tingle. Alternatively, admiring the canal from above and taking pictures is equally breathtaking. And for the fearless ones who want to live life to extreme, there are bungee jumping facilities on site!
