1Lefkas (Lefkada)
This Greek island in the Ionian Sea is one of the few islands in Greece you can actually drive to — it’s connected to mainland Greece by a causeway. Even though it’s technically not a freestanding island, it’s just as breathtaking as its island neighbors, with white-sand beaches and charming Greek villages. One of the island’s most iconic beaches is Porto Katsiki, backed by an enormous, awe-inspiring cliff.
