Hi @cmgilliatt another suggestion would be to check out San Gorgonio. It's a long hike to the summit, but you can always camp at halfway camp (not really halfway) or high camp to make it a shorter adventure for the kids. 

Another suggestion- check out the Mosquito Lakes area near Mineral King. This is in the southern Sierras, but on the western side. One of my first and most memorable backpack trips. It has some great alpine lakes, a shorter hike in, and a pretty cool drive to the trailhead too. 

Hope this helps!
