Where would you go with three 17 yr olds in Wales?

Hi, never ever been to Wales, looking for a week in Aug. There seems to be a lot of s/catering options but where to go? Boys would like a sandy beach, I would like walking distance of nice cafes/shops/dh would like nice gardens to visit and dd would love art galleries! Mixed bag! TIA. x

Wow...........thank you! So tonight is going to be serious search for accommodation, brilliant info thank you so much :)

A friend was telling me today she is going to Snowdon to do a mile long zipwire and a visit to a cave which has trampoline nets strung up inside it. Reckon thatd be right up a 17yps street!

I think that attraction was mentioned a few pages back and we've now added it to our itinerary in the summer.
