It would be hard to beat Blanchard Springs Recreation Area in Ozark NF. Good fishing, super campsites, a cave to explore, great hiking, Fall colors (maybe) - I could go on. Take a look at the Ozark NF's web pages on our website. I would also suggest a visit to Mountain View and the Folk Park/Museum there and a trip into Fifty-six for a piece of pie there. You can miss the place as it is the only eatery in town.
Sam's Throne campground was pretty outstanding, too, especially if you are a tent camping rock climbers.
Maybe there is more to do in NW Arkansas but Ozark NF kept me busy. Click on one of the icons upper left on this page for Ozark NF campground descriptions.
