Port Vell, Port Olimpic and Barceloneta Beach
Barcelona's port is Catalonia's largest port. The Port Vell (the old port) is one of the three zones of the port which comprises two marinas/yacht harbors, a fishing port and station for ferries. In the central area the port houses a multiplex cinema, IMAX, Europe's largest aquarium and Maremagnum - shopping mall and nightlife complex - the only commercial mall in the city that can open on Sundays and public holidays.
Barceloneta Beach
Another maritime area which characterizes Barcelona's waterfront is Barceloneta beach. The Barceloneta beach is the most distinguished and well-known beach in Barcelona. There are more than 1100 metres of beach to enjoy activities in the sea and on the beach. The beach is ideal for a day of leisure, but expect large crowds on Saturdays when locals show up. There is lots of bars and restaurants nearby. The negative side are lots of cigarettes and bottles in sand. Due to large crowd you should be careful and pay attention to a pickpockets.
Port Olimpic (Olympic Marina)
Barcelona’s Olympic Marina is one of the city’s most popular leisure areas. Located opposite the Olympic Village, it was built in 1991 during the redevelopment of this area of Barcelona. Port Olympic is very happening and lively place to be in Barcelona both during day and night. The restaurants are generally good but pretty expensive. Many pubs, bars and terraces facing the port will give you an opportunity to experience Barcelona's night life.
