We are staying in Leptokarya and would like to see Thessaloniki. We will have a car but we would like to avoid driving in Thessaloniki. We would like to do the hop on and off bus tour that begins at the White Tower. What is the best way to get the White Tower? Would it be easiest to take the train from Leptokarya to Thessaloniki, then a bus to White Tower? Or, drive and park on the outskirts, take a bus in?
