Double Lake outside of Coldspring is good. It's close and more importantly, there is some greenery between the campsites! I camp to see woods not my neighbors!
If you are the type that wants a shop, and boat rentals or even a proper lake after this drought, this may not be for you. If you want to hike or bike some trails, see some critters, and just generally enjoy the woods, this is a great place!
And, unlike state parks, you don't have to pay for wood for your campfire. Just go find some. Although they do sale precut wood for the older folks!
There is also a restaurant in Coldspring that delivers meals and bags of ice to your campsite.
