La Rambla is a very popular pedestrian walkway stretching .75 miles through central Barcelona from Plaça de Catalunya to the waterfront. Along the tree-lined promenade are historic buildings (such as the Gran Teatre del Liceu and Teatre Principal), restaurants, shops, markets, kiosks and crowds of people. As you approach the terminus of this famous boulevard at the Christopher Columbus Monument, stop to watch the street performers. All of them wear elaborate costumes. Many pose as statues until they spring into action after receiving a tip.
