With all that there is to see in the Peloponnese, few people stop to visit the archaeological site of ancient Corinth. Even us, who passed alongside hundreds of times, we had never gave it a chance… Not only it is worth to be seen, but it is also a great overnight stop for those who are going to or coming back from Athens.
The archaeological site [37.90637,22.87955] is surrounded by the village and the various tourist shops. Open from 8am to 3pm, and in summer until later, the entrance to the site and museum costs € 6 (reduced € 3). The site covers a fairly large area and to visit it takes a couple of hours, also including the museum. The temple of Poseidon is in good condition and the location under the castle of Corinth impressive.
On the left the free municipal parking where we stopped to sleep [37.90751,22.87991], quiet and practically next to the archaeological site.
For those who prefer, close by there is also the friendly Corinth camper stop, as an option.
