100% of Wildlife Management Areas in the state of Arkansas require a Hunting license or WMA camping permit purchased though Arkansas Game and Fish.
WMA Regulations are very easy to find on the AGFC website.
Know the seasons and be courteous. There is pretty much at least one open hunting season from September each year through the following May.
There is only a handful of sites spread throughout the WMA and you can only camp in those designated by the game and fish.
This isn’t the national forest, you can’t just pull off and camp anywhere you please.
