What can we do in northern france with teens?

[Saveourholiday9]

We are going to northern France for a few days this week and the weather forecast looks terrible. We’re staying with family in a rural area with patchy wifi and have 5 secondary age children to keep entertained. We will have cars and happy to drive to suitable activities.

Original plans were a day at Le Touquet beach and another day at Parc Bagatelle (would still like to try this). Does anyone have any recommendations for indoor activities which will keep the teens happy in this area please?

Not indoor activities but my kids were all history tragics at high school age and visiting the war cemeteries was a highlight of more than one holiday. Raincoats and hot chocolate after? Obviously not everyone’s idea of fun.

There’s an amazing aquarium called Nausicaa in Boulogne sur Mer. Apparently it’s the biggest in Europe.
There’s also an indoor swimming pool/waterpark with flumes etc… called Belle Dune Aquaclub

Just remembered that Lille has a big indoor karting track.

@Fivemoreminutes1 thank you for your help, unfortunately they’re not likely to enjoy the historical sites, but go karting is worth a look!

nausicaa aquarium is amazing. Well worth a day out. Le Touquet town is really nice as is the beach. Depending where in Northern France you are going there are lots of lovely things to do / see. The Normandy landing beaches are really interesting and my teens even enjoyed the odd museum there. Saint Aubin sur Mer is my favourite place.
