4Las Ramblas
This is one of the busiest tourist spots in Barcelona. It is a pedestrian-friendly thoroughfare located in the very heart of the city. It’s busy both day and night.
During the day you can purchase souvenirs from one of the many stands, enjoy the music of buskers, watch other street performers, buy artwork from one of the local artists, and then kick back with a bite to eat at one of the numerous alfresco cafes. After sunset, you can cruise the local nightclubs and bars found there.
