Paris, the Cote d'Azur and Barcelona

This city was made for walking. Stroll grand boulevards with sweeping views of the city, pristine parks with trees planted in perfect rows, and narrow streets crowded with vendors selling flowers, pastries and cheese. Then head to the Île de la Cité, a small island in the Seine, to see Notre Dame Cathedral. Look up at the great stone buttresses, grotesque gargoyles, and massive stained-glass windows.

Visit one of the original college towns. Since the Sorbonne’s founding in the 1100s, the Left Bank has attracted not only intellectuals but also the cafés, bookstores, and cinemas that tend to accompany them. It’s also attracted its fair share of famous residents – a plaque marks one of Hemingway’s apartments on rue du Cardinal-Lemoine, and the imposing neoclassical Panthéon holds the tombs of Voltaire, Rousseau, Victor Hugo, and Marie Curie.

The world's largest art museum, the Louvre is housed in a medieval fortress-turned-castle so grand it's worth a tour itself. You walk through the 71-foot glass pyramid designed by I.M. Pei and added in 1989, and step into another world-one with carved ceilings, deep-set windows, and so many architectural details, you could spend a week just admiring the rooms. But check out the art on the walls. The Mona Lisa is here, as well as the Venus de Milo and Winged Victory (the headless statue, circa 200 BC, discovered at Samothrace). The Louvre has seven different departments of paintings, prints, drawings, sculptures and antiquities. Don't miss the Egyptian collection, complete with creepy sarcophagi, or the collection of Greek ceramics, one of the largest in the world. (Please note the Louvre is closed on Tuesdays.)

What's that huge white arch at the end of the Champs-Élysées? The Arc de Triomphe, commissioned by Napoleon in 1806 after his victory at Austerlitz. Your licensed local guide will elaborate on this, and other Parisian landmarks. See some of the most famous sites, including the ornate, 19th-century Opera, the Presidential residence, the ultra-chic shops of the Rue du Faubourg St-Honoré, and the gardens of the Tuileries. You'll pass the Place de la Concorde, where in the center you’ll find the Obelisk of Luxor, a gift from Egypt in 1836, and the Place Vendôme, a huge square surrounded by 17th-century buildings. Spot chic locals (and tons of tourists) strolling the Champs-Élysées. Look up at the iron girders of the Eiffel Tower, built for the 1889 World's Fair to commemorate the centenary of the French Revolution. See Les Invalides (a refuge for war wounded), the École Militaire (Napoleon's alma mater), and the Conciergerie (the prison where Marie Antoinette was kept during the French Revolution).

The ultimate palace, Versailles was built by Louis VIX, and housed the royal family and its groveling court from 1582, when the Sun King moved in, to the French Revolution. Everything in Versailles is worth a look, from the 250-foot-long Hall of Mirrors, with themed salons-"war" and "peace"-on either side, to Marie Antoinette's faux country hamlet. When being a queen became too much to bear, she would pretend to be a commoner, tending her sheep and wearing peasant clothes. (Please note Versailles is closed on Mondays.)

See the city from the water on an hour-long cruise along the River Seine. The Seine cuts right through Paris, dividing the city in half. See the Eiffel tower rising up on the Left Bank, the walls of the Louvre on the Right Bank. A guide will point out other monuments and architectural marvels as you pass, many of which are illuminated by clear white light at night.

On the Mediterranean coast, five miles from the Italian border, lies the tiny, glittering independent state of Monaco. Ruled by the Grimaldi family since the 13th century, Monaco is the epitome of French Riviera glamour. Your Tour Director will lead you on this brief adventure. See the casino that Charles III opened in the 1850s to avert financial straits; needless to say, his plan worked--so well, in fact, that Monaco is a nearly tax-free state. Drop in on Prince Rainier (OK, see his house, the Palais du Prince), and visit a parfumerie in nearby Eze, where rich scents are made from local flowers such as jasmine, rose, and lavender.

The Côte d'Azur's largest city spills down the hillsides to pebble beaches that line the shore. Your Tour Director will show you around the narrow pedestrian streets and tiny squares of "Le Vieux Nice" (Old Town), which is sprinkled with old palaces and mansions. Stroll down the Promenade des Anglais, which runs parallel to the water. Backed by Nice's grand hotels, the Promenade was built in the 19th century for the British who flocked here en masse.

Lush lavender fields, olive groves, terra-cotta roofs, and ochre walls lit by golden sunlight...your Tour Director will guide you through the splendor that is Provence. Explore legacies of the Roman Empire like the Pont du Gard aqueduct, a sophisticated work of engineering that is intact after more than 2,000 years, and visit the Nîmes amphitheater. Built by the Romans nearly 2,000 years ago, it was once the site of gory gladiator and animal combat, and is still used today for performances and bullfights (some things never change). Also see the medieval ruins of Baux-de-Provence.

Imagine a perfect jewel of a Mediterranean village, bright boats bobbing on azure water and pastel houses providing shade from a lollipop sun. You’re in Collioure. Hidden between the Pyrenees and the sea, this laidback town has combined the best of Spanish and French resort cultures to become the perfect relaxation spot (and a former favorite of both Matisse and Picasso).

Tapas purportedly originated when bartenders set a small plate ("tapa") over patrons' glasses of sherry and wine to keep the flies out. The bartenders starting piling the plate with cold cuts, olives, or salad, and the bite-size snack was born. (We're unsure how they kept the flies out of the cold-cuts... maybe that's how the sandwich was invented?) Over time these working-class snacks have become more elaborate, with each region adding its own specialties and cooking techniques to create unique tastes and combinations.

See brilliant Barcelona, a city of graceful Gothic churches, wrought-iron balconies and wide, grand avenues filled with outdoor cafés. Throughout the city, daringly innovative buildings sit side-by-side with the medieval past. A licensed, local guide will show you some of the high points of this architectural showcase. First stop: the pointy spires of the La Sagrada Familia (Church of the Holy Family), a half-finished church complex that became the obsession of Barcelona's famously eccentric architectural genius, Antoni Gaudí. Continue to the Spanish Village, where you'll view replicas of famous buildings and sights from every region of Spain. Then step back to the past with a journey up to Montjuïc (Hill of the Jews). See the fortress built atop an ancient Jewish cemetery. Site of numerous battles to control Barcelona, this hill was also the location of the 1992 Olympics.

Flowers, pedestrian boulevards, and decorative pavement make Barcelona a great walking city, and your Tour Director will show you where to stroll. See the Mercat de la Boquería, where the bright colors of fruits and vegetables, spices, fresh seafood and meat -- not to mention about a hundred different types of cheese -- vie for space in the market stalls. In the city center you'll see the Monument a Colom, a towering statue of Christopher Columbus. Gaze at the city stretched out before you, the mountains in the distance, and the Mediterranean Sea at your back. Then it's on to the best walk in the city, Las Ramblas, a mile-long pedestrian street that offers up the carnival of urban Barcelona. Have your palm read or browse through the strip's famous open-air shops. Enough walking for one day? Pull up a chair, order a café con leche, and watch the parade of street performers from your seat.
