Levkas (Lefkadha), located some 80 km south of Corfu, can be reached by ship while making your way in or out of Greece and In combination with other Ionian Islands. But Levkas enjoys a unique distinction: it can also be reached directly by vehicles over the causeway that links the island to the mainland opposite the northeast tip. This causeway, incidentally, highlights an argument that has long divided the experts: that is, has Lavkas always been a true island or was it once simply an extension of the mainland? This question then comes down to whether the isthmus now here has always been here; some insist that it has been and point to signs of a canal that the early colonists from Corinth dug here and a bridge that the Romans then built. Others believe that the isthmus has been built up in more recent centuries by the accumulation of sand and silt – so that Levkas has to be regarded as a true island.
