With 35 aquariums and 11,000 animals from 450 species Aquarium Barcelona is a fantastic destination for any mini-Jacques Cousteaus in your family. It consists of 21 large aquariums, a spectacular Oceanarium, a children's area and Planeta Aqua, an entire floor dedicated to our vast, salty, watery oceans.
