UK long weekend with teenagers in April

[kvec]

Hi all
Can anyone recommend somewhere to go with teenagers in April? Looking for a long weekend and originally thought of north wales to do Zip world. Turns out my youngest isn't keen on the big ziplines yet and we have already done other activities there before.
They love watersports and any other adrenaline places and need to be kept busy at all times lol. Looked at centre parcs but that is way out of our price range in regards to activities.
I don't mind where we go apart from Scotland as too far from London.
Anyone had a successful busy long weekend with teens? What did you do? I am thinking of Cornwall too but as we can't guarantee the weather i would worry the majority of things would be beach based and a wash out.

What about Hafan y mor haven site in north wales? www.haven.com/parks/north-wales/hafan-y-mor

Plas Menai, does all kinds of sailing, canoeing, coasteering etc on Anglesey.
Climb Snowdon?
Wild water swimming?
Visit Aber falls?
Visit RAF Valley and watch the fighter jets while eating fish and chips?

Either the Alton Towers hotel or get a cottage nearby and go to the water park, it's about £20 per head to go in if not part of a hotel package. You could obviously do the main park as well but if you didn't want to there is plenty to do in the actual hotel itself.

This is a great site in a great location, if the like water sports you can surf at Hells Mouth (Porth Neigwl In Welsh)
Lovely desolate beach but tranquil too.

This place is nearby, not cheap but great fun, we went Shooting, Go Karting and did some archery

Cafe Largo in Pwllheli is fantastic with great staff too, in a nice near the beach location but also great on a rainy day
