Looks like 5-6 camp grounds around the lake or close by. Also not too far away from the Diamond Fields at Murfreesboro. All just off I30 heading for Texarkana.
I personally liked camping farther up north starting at the Arkansas River where the rocky high country of Arkansas and Missouri are at.
I tell you what - Arkansas is sure loaded down with good fishing holes. I believe you go in any direction for 30 minutes and be in a great fishing hole you have never been in before haha...
I was stationed at Little Rock AFB for four years in the early 60s and we did the Radio Comms for the Misslle Silos back then... Work all day and then fish our way back to base haha... Everyone of our Af trucks had fishing gear in them behind the seats hehe...
I need to head down that way myself and see what it all looks like now. Have done a many of cross road trips over the years thru the south part of Arkansas making runs between Montgomery Al and Wichita Falls TX...
