I am not familiar with anything within a couple hours of Memphis. There are many places about 200 miles. So if you have more time... here are a few ideas
Eminence, MO - Jacks Fork and Current Rivers , National Scenic riverways (Alley Spring NPS, Current River SP or the new MO State Park Echo Bluff campgrounds--kayaking, caves, fishing, springs
Yellville, AR - Buffalo National River (go early in summer for flow)Buffalo Point campground NPS- kayaking, fishing
Lake Ouachita, AR - State park, beautiful very clean and deep lake
Near Russellville, AR -Petit Jean SP, Mount Magazine SP beautiful area
Bull Shoals, AR - Bull Shoals SP below the dam, trout, also the lake
Southern IL - Garden of the Gods, 12 primitive sites, Giant City SP, Ferne Clyffe, lots of hiking trails, rocks. Cave in Rock and campground, free ferry nearby to KY to an Amish town to explore.
