Arkansas has a number of great hikes. I'd stay out of the woods here between mid May and late September unless you're just into dozens of tick bites.
Outside of the Butterfield, Ouachita Trail, and Ozark Highland Trail there is the Weddington Trail, Caney Creek/Buckeye Trail, and Eagle Rock loop in the western part of Arkansas.
Hobbs State Park is rocking if you bring your guns!
Enjoy our woods and get to know a hill billy. You wont regret it.
I'm also a big fan of Palo Duro just south of Amarillo, TX.
