For family friendly I can think of a few I've done:
Cascade is the first one that most think to do, and its a 46er...gets pretty crowded...think it took us 2hrs each way when we did it a few years back. Great view though.
Mt Jo has a nice view and isn't very long. I've only done it in winter.
Owls Head super easy maybe 45 mins. Great view. (Trail might be closed on weekends now I heard?)
Just did Baxter two weeks ago, about an hour each way, very easy, and great view.
Skiing is not a sport, it is a way of life.
