You'll be picked up from your accommodation in central Barcelona early in the morning and head to Passeig de Gracia, one of the city's main boulevards. Walk on the street's intricately paved stonework, designed by the legendary Antoni Gaudi. Shop at one of the many boutiques that line the boulevard, and admire the striking facades of the modernist buildings while listening to your guide's commentary. Snap photos of architectural masterpieces like La Pedrera, Casa Batllo, and Casa Lleo.

You'll also see the Eixample, designed by Ildefons Cerda. Pass the Hospital de Sant Pau as you make your way to La Sagrada Familia. Learn about the different parts of the building, their symbolism and the designer that created them. Continue to the Ciutat Vella neighborhood. Stop at Arc de Triomf and the Parc de la Ciutadella, an old fortress that is now a city park. Admire the Castle of the Three Dragons or the Grief, a sculpture by the lake before walking down La Rambla to the new World Trade Center.

Afterward, climb Montjuic for spectacular panoramic views. See the facilities from the 1992 Olympics, Palau Sant Jordi, and the "urban-ism" designed for the International Exhibition of 1929. Before getting dropped back off at your lodgings, explore the Gothic Quarter with your group and guide.
