To ask where to take ND teens on holiday

[ADHDgirl]

So I’m looking to book a summer holiday next year, I’ve never taken my daughters 13&14 abroad before and I’d really like to do this next year. One has ADHD & the other LD/adhd, they both need a lot of stimulation and a lot to do, but I’d also like to be able to soak up some culture? I’ve never been abroad and so I was wondering if anyone had any suggestions I could look into.

How about Barcelona? It's a beautiful city and there's plenty of culture. It's also by the sea so there's a beach. You can hire bikes and there are two cable cars with amazing views across the city.
The food is fabulous too.
There's so much more to say about it, but I love it. I've been twice and would go back again.
