Discover more than 8,000 sea creatures from 4 ocean habitats at the Oceanário de Lisboa with a pre-booked entrance ticket. Immerse yourself in the North Atlantic, Antarctic, Temperate Pacific, and Tropical Indian Ocean.

Join the 28 million visitors from 182 countries that have visited the Oceanario in Lisbon since it opened in 1998, making it one of the most popular things to do in Lisbon. Located on the grounds of the Expo 98 site, it is the largest indoor aquarium in Europe. Your entrance ticket allows you access to all permanent and temporary exhibitions. Celebrate life on earth through stunning displays of more than 8,000 creatures from 500 species and learn about the complexity of the world’s oceans. Divided into 4 separate bodies of water - representing the North Atlantic, Antarctic, Temperate Pacific, and Tropical Indian Ocean - large acrylic panels cleverly divide each from a central aquarium to create the impression that all living creatures roam in one single mass of salt water!
