Guessing you want to stay closer to the TX border if possible. Sam Houston State park is in the Lake Charles area. Good fishing all around. Tenting is something i gave up many years ago though. I need a shower, bed and AC for my camping experience to be enjoyable now days.

Course I do have to go there some time this month for a wilderness search and rescue training school with an overnight survival senario included.

Bring plenty of off and thermocells.
