Cagle Recreation Area is one of my favorite places to camp.  It's just an hour north of Houston and in a beautiful, peaceful wooded setting.  Although you're not far from the city, you feel like you're out in the middle of nowhere.  The campsites are mostly level, well kept, and there's ample shade.  All are full hookups I believe.  There aren't too many waterfront sites, but if you book early enough you may be lucky enough to get one.  Even if your campsite isn't on the water, many have great views of the beautiful lake.  There is a boat ramp.  Sites have fire pits and are large enough to provide lots of privacy.  Bath houses are sparkly clean and nice.
