5. Corfu, the other island Jeff visited, is at the north end of Greece and far more lush in its appearance. It's "almost tropical," says Jeff. The island is particularly popular with U.K. expats, given that Corfu was a 19th-century British protectorate. Because of that, you'll find English spoken here, as well as British medical professionals. International communities thrive. Outdoorsy types have not only the beaches, coves, and mountains to explore, there's the Corfu Trail that winds through the island for 138 miles and is untouched by any hint of mass tourism. © Jeff Opdyke/IL
