Keep your eyes peeled at La Rambla de Sant Josep — you're bound to find a great travel trinket among the stalls here. After you've had a good look at the wares, grab something to eat from one of the nearby food vendors.
Situated in Sant Cugat del Valles, this community marketplace is worth a visit. But you'll find tons more to explore in this area. Sagrada Familia, Camp Nou, and Park Guell are within close reach of La Rambla de Sant Josep.
