Don't backpack too far and too long a time. Bring lots of snacks that the kids like. Don't let them carry too much weight. Find a good fishing spot (worked for both my boy and girl). Bring games for at nite. The hard part for me was the backpacking part. I have shots of my daughter at 8 years old giving me the stink-eye in the rain as we are closing the gap on a 1000ft elevation gain. She had a great time once we got there but getting there was rough.
