Pompeii is a Roman town frozen in time, thanks to a devastating eruption of Mount Vesuvius in 79 AD. Explore houses from modest to majestic; see Roman shops, baths and brothels; or apply your high-school Latin to the graffiti that's still visible on some of the walls. End your visit at the Villa of the Mysteries, and try to interpret its amazing, bizarre frescoes—scholars have debated their meaning for years.

Stretching along the southern side of Italy's Sorrentine Peninsula, the Amalfi coast dazzles with its mysterious grottos, craggy cliffs and shimmering bays. Grab a seat on the sea side of a regional bus to soak up views on the fabled route from artsy Positano to Amalfi. Ravello offers some respite from the crowds, plus the stunning Villa Cimbrone, which overlooks the Bay of Salerno. The winding streets of Sorrento's historic district are filled with craftspeople. Capri is only a hydrofoil or ferry ride away.

Romantic Naples, two hours south of Rome, is the largest city in southern Italy. It has some of the world's best opera and theatre houses and is often called an open-air museum, due to its many historic statues and monuments. Join families on the promenade as the sun sets on the Bay of Naples. View finds from Pompeii and Herculaneum, destroyed by Mount Vesuvius in 79 A.D., at the Museo Archeologico Nazionale or revel in the art and architecture of Museo Cappella Sansevero, built in the late 1500s.

One visit to the Yorkshire Dales and it’s easy to understand why the unspoiled countryside is the setting of so many novels. Must-see sights among the land’s lush woodlands and expansive moors include Hardraw Force (the longest single-drop waterfall in the North), Gordale Scar, and well-known hill range, the Three Peaks. Less adventurous visitors can rest easy, walking through the manicured lawns of Parcevall Hall Gardens or appreciating Skipton Castle’s medieval architecture. Although some prefer to take in the land’s wild beauty by foot or horse, the most popular way is via one of the park’s famed cycling routes.

Called Sørlandet, Norway's South Coast is known for its rocky coastline, its whitewashed houses and its idyllic archipelago. This warmest area in the country draws many resdents for a summer holiday. Kristiansand, the biggest city here and fifth-largest in all of Norway, has many lovely beaches, a very good zoo (Norway's most visited attraction) and a number of historic buildings. These date from the period of the city's 17th-century founding and are located in Posebyen, the old town area.
