On the Aegean's eastern edge, the Dodecanese present perfect Greek vistas of whitewashed walls, turquoise blue skies and seas. Island-hopping by ferry, hydrofoil or catamaran is a splendid way to get into the leisurely pace. Once docked, you'll find many of these twelve idyllic islands are easily explored on foot. Don't miss Rhodes' Acropolis, the ruins of ancient Kamiros and Valley of the Butterflies or the Askepion ruins on Kos. Tiny Patmos is known for the cave of St John of the Apocalypse.
