Much more than just an aquarium, this enormous space-age 'aquatic world' is divided into three pavilions containing polar, tropical and temperate ecosystems. Highlights are the shark tanks, mangrove and rainforest sections, colourful tropical reefs, seals and the icy-cold penguin display. In addition to the animals, there are numerous films and interactive displays and it's educational for both children and adults alike. It's about 3km east of the city centre; take bus 3 from place de la Liberté.
Tip: buying your ticket online for the same price allows you to skip the queues (which can be very long on wet summer days).
