Where the Rambla ends the water begins: the old port that the 1992 Olympics turned into yachts and timber walks — holding Barcelona's Aquarium with its famous 80m shark tunnel and the floating Maremagnum mall. The aquarium ranks among Europe's best for families; the old iron port cable car (1931) links Barceloneta and Montjuïc with rare views; sunset on the boardwalks closes the Rambla day naturally.
