What did you do when teenagers no longer want to camp?

I agree with the advice to take them to see or do things they want to do or see.
As a teenager, I can recall that the only thing I complained about was that Dad always wanted to go to the backside of the beyond. no people(boys)no activities and nothing to do but look for wildlife by day and the stars at night. borrrring :)
nowadays, I like to get as far away from people as I can get.
