We enjoyed camping at Double Lake.  The campsites are huge and well kept.  I believe all have full hookups.  We had a lakefront site which had a private little path to the lake.  The shore was good for fishing.  There is a trail which goes around the whole lake, and it was such a nice hike we did it several times.  The woods are beautiful and bath houses are clean and well supplied.  There are plenty of shady sites, which makes this a great campground for summer in Texas.  There is a swimming area but we didn't get in the water.  We will definitely camp here again.
