On the Greek Islands, Rudy Maxa gets familiar with the ferries as he island-hops the Aegean. Sun-drenched, upscale, and exotic, Santorini sits on the rim of an ancient--but still active--volcano. At one end of the island, the archeological site at Akrotiri uncovers a city frozen in time by the volcano's eruption 3,600 years ago. The island of Naxos offers serenity, a low-keyed pace, and bargain accommodations. Rudy catches some R&R on trendy Mykonos, and then heads to sacred Delos--an uninhabited island covered entirely with ancient ruins--and the place where the great god, Apollo, was born. Rudy gives tips on discovering little off-the-beaten-path surprises.
