I have No idea with public transport. We had a car rented.

Sorry, I am not sure. However we viewed the boats passing through the canal from the road & bridge above the canal.

The boat goes from the eastern end of the canal and costs €25 each for the return trip and it's cracking! It's also right next to one of the submersible bridges. I got lost at one stage and I stopped and asked the way, it worked too! You drive down to the quayside and there is loads of parking.

There are many companies that offer the tour, look for them here in tripadvisor or google

There is loads of parking on the right just as you have driven over the bridge with Athens behind you

It appears that a bus marked "Stathmos Korinthou" passes by on highway 8. You should keep checking, as I am not certain

My reply would be the same as a previous one. Go to Ancient Corinth, ask at one of the taverna's for directions, it is very close about 15 min.

Good day again, Ursula. From the material we studied in Greece and notes we brought back home, there are a few sources which we suspect will be helpful. Trip Advisors does not allow the inclusion of specific URLs, but you might search Google for any or all of these. EnjoyCorinthia, Inspirock, or Azamara Club Cruises. If none of them are right up your alley, they are most likely able to point you in the right direction. We both wish your and your group a wonderful experience. If you feel we might be of further help, please do not hesitate to send us a message from our profile page.

For some asinine reason, Trip Advisor will not allow a URL to be posted in an answer. I'm sorry, but it's their rule, and none of my own. Search Google, Yahoo, whoever, for "Greece Corinth Canal Boat Tour". You will love the experience.

My płynęliśmy jachtem, szukaj wycieczki kanał koryncki na tripadvidor, przy wybrzeżu od zatoki saronskiej stał też wycieczkowy statek
