Go in the fall or early spring - bring strong repellent
We were eaten alive. It is to be expected that you will attract mosquitoes, but this was extreme. Nothing we did short of covering our bodies in toxic chemicals would stop them. Even then they surrounded us. We also came home with fleas, also not the end of the world, but unpleasant.
The park itself is must see for fans of the forests of East Texas. The lake is so intriguing and the history is very interesting. It is a heavily populated and used lake... I wouldn't describe it as a peaceful area. I could also do without the partisan political imagery surrounding the park. The park is large enough and the campsites are embedding into the woods.
Campsites are thankfully spread out and when were there it was maybe 35-40% capacity. Lots of privacy. Be sure to stop during the day and listen, you'll hear trees and birds.
Park is situated among lake towns, but during the day and morning it is very quiet. evening and nights are much louder. The trails need some updating.
Amenities used:

Be smart and come prepared and you'll be wowed.
