If your family is in to primitive camping, there are a number of sites on Big Run Rd. outside of Blackwell that can be reserved free of charge from the DCNR. We went up one weekend during the rattlesnake roundup in Morris when all of the campgrounds in the area were pretty well booked and there wasn't a soul in sight. I personally can't stand going camping just to be surrounded by people, I can do that in the suburbs. Rattlesnake rock is right down the road which has a pretty awesome swimming hole, and you might just find a few rattlers. If you're planning on going up yet this year it might be pretty tough doing any sort of kayaking/tubing unless you target the downstream areas, which are a little less wildernessy. Lots of dirt roads to go for a drive, catch some vistas along the way. I haven't been up in a few years but can't wait to get back when the littlest is a little less little.
