Aquarium Barcelona

The largest Mediterranean aquarium in Europe, located in the Port Vell harbor. In addition to 11,000 marine animals from 450 species, the main attraction is the Oceanarium — an 80-meter underwater tunnel through which sharks, rays, and enormous fish swim past you. Interactive zones for children (Explora!), a 3D cinema, and educational programs with feeders make it a top family outing in the city. Ideal to combine with a stroll through Port Vell and the nearby La Rambla. Accessible by metro at Drassanes or Barceloneta stations.
