One of Poland’s most beautiful cities, Gdansk, on the Baltic Sea, has played major roles in history, especially in the 20th-century. It was the 1939 flash point of World War II, and then in 1980, the birthplace of the Solidarnosc labor movement, ushering the end of Communist domination in Eastern Europe. Gdansk’s Old Town, painstakingly reconstructed to its Hanseatic League glory after being leveled in World War II, is a highlight. The 14th-century Town Hall houses the city’s historical museum.

As the oldest resort town on the French Riviera, Hyeres has been entertaining France’s aristocracy for centuries, and its medieval old town—perched on a hilltop overlooking the coastal islands and salt marshes—maintains an air of elegance.

The beaches that stretch along Kudasi's Aegean coastline are as diverse in terrain as they are in ambiance. Ladies’ Beach, thusly named because it was once a for women only, is packed with nightclubs, souvenir vendors, restaurants and, of course, sunbathers and swimmers. Grass-lined Gold Beach is well-manicured and peaceful. Ride a horse from there to Long Beach, a playground of beach bars, pool tables and water sports.

Once known for smog, traffic and tacky architecture, Athens is a city reformed thanks to fortunes brought by the 2004 Summer Olympics. Spotless parks and streets, an ultra-modern metro, new motorways, an accessible airport and all signs in perfect English make the city easily negotiable. Meriting more than a stopover en route to the islands, sophisticated Athens sites include many pillars of Western history, from the Acropolis to the Temple of Olympian Zeus, as well as treasures in the National Archaeological Museum.

In the chic, sun-drenched Costa del Sol town of Marbella, hints of its former Moorish occupation mingle with modern-day resort amenities. Bask on the sands of famous La Fontanilla beach or ricochet among the area's family-oriented water, wildlife and theme parks. Experience the Andalusian charm of the historic quarter, filled with whitewashed buildings, remnants of a ninth-century Arab fortress and fragrant orange trees. End a relaxing day with a dish of the cold almond soup ajoblanco and some of the region's excellent dessert wine.
