Stretching from Plaça Cataluyna to Port Vell, this one-mile-long pedestrian boulevard is a must for visitors to Barcelona and is one of the city's most popular destinations. As you walk under the shade of plane trees, you'll pass street performers, human statues, florists, gelaterías, and candy stalls, all while smelling the cooking aroma of crema catalana and gofres.

With its roots dating back almost 1000 years, La Boqueria is a market of over 200 stands huddled under a distinctive glass roof. Here, you'll find vendors selling fruits, vegetables, meats, fish, and olive products. Purchase a fruit smoothie as you enter, then peruse the stalls as the bustling of the market surrounds you. It's a sensation for the senses, whether you buy anything or not.

Containing its famous mosaic lizard—seen on postcards around the Globe—Park Güell is a fantasy land come true. Opened in 1926 as a collaboration between entrepreneur Eusebi Güell and architect Antoni Gaudí, this whimsical space contains mosaic-covered fountains, buildings, sculptures, and colonnades, all built in the iconic Gaudí style. You can even visit Gaudí's House-Museum, where he lived for twenty years.
