If there’s one thing you really shouldn’t miss during your stay, it’s the Cité de la Mer, a one-of-a-kind leisure and discovery park. You can discover three breathtaking areas.
The aquarium
Dive into “The Ocean of the Future” and discover 17 aquariums filled with a multitude of fish. The Abyssal Aquarium is the deepest aquarium in Europe. Evolve and share moments of wonder thanks to a fun trail.

Le Redoutable
Le Redoutable is the first nuclear-powered ballistic missile submarine (SNLE) built in France. With an audioguide, enter this 128m-long giant and discover all the secrets it holds: from the engine room to the command post, via the cafeteria and crew cabins, you won’t be disappointed!

Titanic exhibition
Extend your visit with the Titanic exhibition. On April 10, 1912, the Titanic called into Cherbourg’s large artificial harbor. Step back in time as you enter the baggage room and discover objects found at the bottom of the North Atlantic Ocean. During this exceptional visit, you’ll experience the final moments leading up to the sinking, as well as the investigation – an exhibition rich in emotion.
