Lefkada and Kefalonia are two of the seven main islands of Greece in the Ionian Sea, west of the mainland. Lefkada is technically no longer an island, as it's now connected to the mainland via a causeway. Kefalonia, the better-known of the two, lies to its southwest. In this outstanding drone video, you'll get an aerial view of some beautiful spots on the two islands, both of which bear the marks of centuries of Venetian rule. Kefalonia's Myrtos beach and Melissani Lake; and Lefkada's Cape Doukato, Kathisma, and Porto Katsiki.
