The Buffalo National River in northeast Arkansas was the first National River. The river runs for 135 miles and is one of the few remaining undammed rivers in the lower 48 states. When paddling the river you'll pass by some steep canyon walls. There are a number of developed as well as primitive areas to camp. We stayed at the Steel Creek Campground which had a large open field for tent camping. It was surrounded by a groove of trees that ran along the river. There's plenty of space for tent camping and some space for hammock camping, but all the sites are available on a first come first served basis.There are some great hiking trails in the area, but the real attraction is the river and the opportunity to paddle it. In the small town of Ponca (pop.13) there is an outfitter/gas station where you can get equipped and arrange shuttle service for a drop-off and pick-up paddle trip. When hiking around the area you'll often hike in the surrounding mountains which overlook the river. It lends perspective to see the topography up close and personal while paddling the river as well as from a distant while hiking in the mountains.
