I cannot explain how to make someone like something. If you're trying to "convert" someone, that might be part of the problem right there. Keep offering, don't be forceful, maybe they'll come around with time. Maybe not.
So far, I'm fortunate to have kids that genuinely enjoy backpacking and camping and actually ask me to take them. Obviously, it's partly because I take them. But beyond that, I can't say if it's to my credit, luck, or both. They are who they are.
They're only 8 and 10 years old now; quite easily impressed by dad still. I certainly hope it stays this way, but we still have a long road ahead of us. Boyfriends, girlfriends, teenage years, peers, etc...It's going to be a lot of competition for sure.
I suppose it's every parent's fear that they will not be like us. But I think it would be a parent's greatest folly to try and force them to.
As I watch mine grow, seeing different personality traits come forth, I have to be accepting of the fact that they might not like what I like...Hell, they could potentially grow up and vote Republican.
What can we do but share and expose them to what we love? If it doesn't take, we must meet them where they are and (gasp!) accept the possibility that we may have to try and find enjoyment in what THEY like to do if we're to maintain a relationship.
