Many including the Romans had dreamed since antiquity to open a canal in the sea that cuts between the Greek mainland and the Peloponnese. Both Ancient Greek and Roman notables, including Nero, tried and failed, until many centuries later in 1893, the Greek state finally managed to complete the feat after many false starts mired by economic woes. Today the narrow canal is impressive to visit, and anyone on the way from Athens to the Peloponnese can stop and admire this challenging marvel of engineering, which has also become a popular point for bungee jumping.

This is first attraction you'll come across before entering the Peloponnese and heading to the remains of Ancient Corinth. The archeological site is intriguing, with the remaining columns of the Temple of Apollo towering over the other ruins. The site is also home to the small Archeological Museum of Corinth which is home to several marble statues and Roman-era mosaics. You can have a bite at the small village right outside the site in one of several little restaurants and procure a few souvenirs from the shops.

A short drive away on top of an impressive mountain rock that reaches 575 meters above sea level lies the castle of Acrocorinth, which saw the likes of the Byzantines, Franks, Ottomans and Venetians pass through its walls, representing one of the most important – and impressive – medieval castles in Greece.

If you're into nature, you can also drive to the Environment Museum of Stymphalia, set on the lake by the same name. In mythology, the lake's hungry man-eating birds with bronze beaks, infamously known as Stymphalian birds and known to be pets of the goddess Artemis, were finally defeated by Hercules.
