Visiting Nausicaá in Boulogne-sur-Mer: an unforgettable experience
Fancy uncovering the secrets and mysteries of the ocean?
Then a visit to Nausicaá should hit the spot! Between the largely ecology-focused exhibitions and watching marine species such as sharks, penguins and a range of tropical fish, Nausicaá is the perfect place for a wonderful family outing.
Planning to spend one or several days on the Opal Coast? Perfect. To satisfy that urge to get away from it all, nothing beats a walk along the Wimereux seafront or at Cap Blanc-Nez. A few kilometres away, a visit to Nausicaá in Boulogne-sur-Mer will carry you into the heart of the vast marine world.
Lovely aquarium, I went with a friend and her grandad, who had to do the route in a wheelchair, and it went really well. The lifts were clearly signposted. The staff were friendly and helpful.
I was also impressed by the new immersive experience.
I really do recommend this aquarium, which, despite some past issues, keeps trying to reinvent itself and bring in new things.
Fantastic! Amazing. An extraordinary day awaits… Young and old, captivated and delighted. The price is justified given the quality of the tanks.
A relaxing experience, with beautifully crafted soundscapes
I'd happily come back every year
Great, very informative, beautiful tanks. Not many people as it was a Monday…👍 so perfect for taking it all in at a relaxed pace.
The restaurant is exemplary!! Homemade food I think — I hesitated, worried I'd end up in some industrial cafeteria, but I was completely wrong!
And the staff were simply as kind as we're sadly no longer used to. I had a wonderful day.
The health protocol, with clear signage, was well respected, with hand gel regularly available along the route.
One small downside: the number of visitors that day felt excessive for the health protocol in place, it was genuinely quite stifling in some spots…
The gift shop is nice and there's something for everyone, young and old…
I'd recommend this visit on quieter days…
It's a cool, enjoyable place to do once with kids.
That said, we expected to see more 🦈 and bigger aquarium tunnels.
That said, it's still a good visit and a good day out.
As for the meal, it's a bit pricey, but the food quality was there, so it's fine — it's not outrageously expensive either.
The gift shop is nice, could be improved.

Nausicaá is more than just an aquarium: it's a key player in the fight for the environment.
Between raising awareness and protecting the marine world
Want to raise your children's awareness of ocean issues and, more broadly, environmental topics? Then don't miss the exhibitions and events run by the Opal Coast's sea centre! These might include feeding time at the tropical lagoon, a virtual show on climate change, or sea lion training sessions.
Visiting the complex as a family? To guide children throughout their visit, Nausicaá has designed an educational booklet aimed at teaching them about the major themes of the sea in a fun way.
The youngest visitors get to step into the shoes of an animal keeper, with a range of games designed for them. Interested in the children's booklet? You'll find it at the Nausicaá shop.
Additional activities run by the national sea centre
For an even more fascinating experience, you can also sign up for activities run by the national sea centre: Behind the Scenes at Nausicaá. Yes, really! If you'd like, the heart of the ocean can be fully opened up to you. For a whole hour, you'll be able to watch the aquarists at work and discover the aquarium's stores and the kitchens dedicated to feeding the fish.
The "coastal investigation" activity. Fancy ending your day with an outdoor activity? The seashore is full of mysteries. Accompanied by a science educator, your mission is to solve them. The activity takes place on the beach at Boulogne-sur-Mer, then in a science lab.
