Time travel is possible, simply by taking a short train ride from Naples. The ruins of Pompeii, unearthed in the mid-18th century, contain 2,000-year-old temples, villas and artworks buried when volcanic Mount Vesuvius blew its stack in 79 A.D. Explore the elegant House of the Vettii, the rich frescoes of the House of the Mysteries and ancient thermal baths. After immersing yourself in history, head for the modern city of Pompei (its neighbor with only one "i") to dine on tantalizing regional dishes.
