Road trip from Barcelona to Switzerland and Cloud - Stop recommendations?

Hi meloners! 🍉

We are going to drive around center Europe and I was wondering if there are cool places we should 100% stop by. Our current itinerary looks like:

• Alicante

• Barcelona

• Marseille

• Alpiness Coliving (Les Hauderes)

• Cloud Citadel

• Barcelona
  

Also, if someone wants to join us, just let me know 🤗

Thanks!
