La Rambla is a street in central Barcelona. A tree-lined pedestrian street, it stretches for 1.2 km (0.75 mi) connecting the Plaça de Catalunya in its center with the Christopher Columbus Monument at Port Vell. La Rambla forms the boundary between the neighbourhoods of the Barri Gòtic to the east and the El Raval to the west.

La Rambla can be crowded, especially during the height of the tourist season. Its popularity with tourists has affected the character of the street, which has shifted in composition to pavement cafes and souvenir kiosks. It has also suffered from the attention of pickpockets. The Spanish poet Federico García Lorca once said that La Rambla was "the only street in the world which I wish would never end."

The course of La Rambla was originally a sewage-filled stream, usually dry but an important drain for the heavy rainwater flowing from the Collserola hills during spring and autumn. The tree-lined central promenade of La Rambla is crowded during the day and until late in the night. Its origins as a watercourse are reflected in the paving design, which appears to ripple like water.
