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.

Paella is a Valencian rice dish with ancient roots that originated in its modern form in the mid-19th century near Albufera lagoon on the east coast of Spain.

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. At the top of Güell Park, another of Gaudí's masterpieces, is a terraced area where you get a wonderful view of the park and Barcelona City. The vibrant colors of the tiles are breathtaking. Then step back to the past with a journey up to Montjuïc (Hill of the Jews), a fortress built atop an ancient Jewish cemetery. This was the site of numerous battles to control Barcelona, and also the location of the 1992 Olympics.

Get a taste of Spain's cultural, political and economic center with a tour led by a licensed local guide. See Madrid's mix of traditional and modern as you visit the Royal Palace, an 18th-century masterpiece. The enormous Baroque palace currently has more rooms (2,800) than any other European palace, but it was originally supposed to be four times as large. The palace is dripping with porcelain, jeweled clocks, amazing ceiling frescoes—the most magnificent, in the Throne Room, was done by the Venetian artist Tiepolo when he was in his seventies. Next take a look at the Neoclassical architecture of the Prado Museum and the Puerta de Alcalá triumphal arch, built to honor Carlos III’s entry into Spain.

Tapas purportedly originated when bartenders set a small plate ("tapa") over patrons' glasses of sherry and wine to keep the flies out. The bartenders started 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.

Race across the country in Spain’s fastest train, the high-tech AVE, which can reach speeds of over 180 miles per hour.

See the twisted alleyways and cobbled streets of Seville with the help of a licensed, local guide. Your first visit will be to the Barrio de Santa Cruz, formerly the old Jewish quarter of the 17th-century. Now, lovingly restored, these properties are among the city’s more exquisite and expensive. Next you will enter the high, fortified wall of the Alcázar, a palace built by a Christian king named ‘Pedro the Cruel’. Now it is the official residence of the king and queen of Spain. End the day with a visit to Columbus’ gravesite.

Charming white-washed houses and ochre-colored palaces with ornate façades. Jasmine-covered balconies and luxuriant parks. Jean Cocteau listed Seville (along with Peking and Venice) as one of the three most magical cities in the world. Santa Teresa proclaimed its beauty was the work of the devil. Decide for yourself as you stroll the streets with your Tour Director. Climb to the top of the Giralda Tower, the greatest symbol of the city. It was once the minaret of Seville’s greatest mosque, built between 1184 and 1196. Later, Christians destroyed the mosque but couldn’t bear to tear down the tower, so they incorporated it into their new cathedral.

Originating from gypsy music and dance in Southern Spain, flamenco dancing has become a Spanish institution. Dancers use intricate footwork and elaborate arm gestures to convey the mood of the music, which can range from lamentation to celebration. Learn about the history of Flamenco, watch dancers perform and give it a whirl yourself!

Granada sits on three gentle hills, which are dwarfed on a clear day by the majestic snowcapped peaks of the Sierra Nevada. Atop one of these hills sits the imposing but delicate Alhambra palace. Golden pink hues give this sprawling renaissance gateway an otherworldly aura. One of the best rewards of climbing up to see it is the view of the city mixed in with orchards, tobacco fields and poplar groves.
