This quintessential city walk delivers high energy, bold theatricality, and design heritage. Just because something is a tourist trap doesn't mean that it can't be fun. If you want to soak up the incredible energy of this most dynamic of European cities with all its color, vitality, noise and smells, you really need to dive right into this drag of market stalls. Its collection of kiosks, shops, cafes and general al fresco mayhem running from the iconic Placa de Catalunya down to the sea is not to be missed. Barcelona's Rambla was originally a watercourse, a sandy arroyo called rmel (Arabic for "sand"). Today seasonal runoff has been replaced by a flood of humanity. No wonder Federico Garcia Lorca called this the only street in the world he wished would never end: the show of humanity rages relentlessly - mimes, acrobats, jugglers, musicians, puppeteers, portraitists, break-dancers, rappers, and rockers stretched out beneath the canopy of plane trees. A pedestrian runway between two traffic lanes, the Rambla remains an essential Barcelona event. The crowds seethe and dawdle. Couples sit at cafe tables no bigger than tea trays while nimble-footed waiters dodge traffic. Peddlers, kiosk owners, parrots, and parakeets along the Rambla dels Ocells (Rambla of the Birds) create a cacophony of birdsong and catcalls that clamors over the din of taxis and motorbikes. Here, in busy Barcelona, the Rambla is permanently filled with squads of revelers, often more animated at 3 AM than at 3 PM.
