Olympia - There are many organised tours using the ferry from Zakynthos town to Kyllini on the mainland to visit the ancient site of the original Olympic Games about 45 mins drive from the port.
Athens overnight trips are available through organised tours or using scheduled KTEL bus services and the Kyllini ferry.
Day trip to Kefalonia - the ferry leaves Agios Nikolaos to and from this island several times daily and there are many official guided tours allowing you to visit and return. Unfortunately the scheduled bus service to Agios Nikolaos is virtually non-existent, so if you don't want to sign up with an organised tour then you will require a taxi or your own transport to link up with the ferry.
