Aquarium de Paris

Aquarium de Paris — also known as Cinéaqua — is an underground aquarium built into the rock beneath the Trocadéro gardens, making it one of the most atmospherically situated aquariums anywhere. Its location means the approach through the tunnels of the Trocadéro hill already feels like an adventure before the first tank is reached. The collection includes over 10,000 sea creatures across 500 species, with the highlights being the walk-through shark and ray tunnel, the jellyfish room with its hypnotic bioluminescent displays, and the 360-degree ocean tank that surrounds visitors completely in underwater blue.

Children respond to the immersive elements immediately — the shark tunnel in particular produces a mix of awe and nervous excitement that becomes a talking point for the rest of the trip. The aquarium also houses a cinema that screens nature documentaries and animated ocean films on a loop, giving parents a quiet sit-down option mid-visit. Multiple touch pools allow children to handle starfish, sea cucumbers, and anemones under staff supervision.

A dedicated children's zone includes cartoon-character installations and interactive screens. The on-site restaurant has a glass wall looking directly into one of the large tanks — eating while fish swim past is a reliably memorable experience. The Trocadéro location puts the aquarium directly between the Eiffel Tower and the Palais de Chaillot, making it an easy addition to a Trocadéro morning.
