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.

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. 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.

Adjust your eyes to some of the most perfect paintings by prehistoric man. (So perfect that even archaeologists wondered whether early man was capable of such a feat.) With nearly one hundred pictures of signs and animals such as bison, deer, horses and bulls decorating the walls and ceilings, it’s been given the name “The Sistene Chapel of Quaternary Art.” Because body heat and breath can damage the artwork, entry to the caves is restricted to 9,000 visitors per year. But don’t worry. A replica of the cave, true to the original, is open for all.

Visit Spain's first National Park situated between the regions of Asturias, Cantabria and León, in the heart of the Cantabrian Mountains, in northern Spain. Its history goes back to 1918, when don Pedro Pidal, Marquis of Villaviciosa, promoted the law to create the Montaña de Covadonga National Park, which was named Picos de Europa National Park on 30 May 1995. This natural area was awarded the UNESCO Biosphere Reserve designation in 2002.

Though one of Spain’s most popular resorts, San Sebastián is not just beaches. With your Tour Director you’ll visit the old quarter, centered around Plaza de la Constitución (known to locals as “La Consti”). Look for the numbers on the balconies around the square – the plaza was once used for bullfighting, and those balconies were rented as private boxes for spectators. The nearby Saint Vincent church, built in the 1500s, is the city’s oldest standing monument.

Dedicated to sculptor, Eduardo Chillida, Chillida Leku feels less like a museum and more like an artist’s sanctuary, just as Eduardo himself envisioned. Take in the warm Spanish sun as you stroll along grassy plains and through rich woodland dotted with Chillida’s enormous abstract artwork. (Feel free to touch!) Then cozy up inside the farmhouse filled with smaller works made from granite, terracotta, wood and paper.
