A highlight of the aquarium is the Planeta Aqua (Water Planet) exhibit, which features animals, such as the crowd-favorite penguins, that have adapted to changing climates over time. There are also mini aquariums set up throughout the building to allow visitors to appreciate the amazing small details of the ocean's flora and fauna that tend to get lost in the bigger tanks.
The Barcelona Aquarium is located on Port Vell. Find shops, restaurants and other entertainment at the Maremagnum complex as well as beautiful views of the marina and beach. This location is also at the base of La Rambla, so it's a good starting point for a walk up the famous pedestrian avenue.
