Aquarium de Paris
An aquarium and cinema may seem like a strange combination, but the two coexist nicely in this attractive space beneath the Trocadéro gardens. In addition to 10,000 fish and a giant tank of small sharks, it promises puppet and magic shows, along with workshops for children in animation, art, and dance (these are offered in French, but the staff speaks English). There are also kid-oriented films showing on one big screen and, for the grown-ups, feature films playing on a second. Book tickets online to avoid lines.
