Yeah, it was nice to see our area in a feature article there.
NG Ozarks Article I haven't hiked much of the trail at all but I have bushwhacked areas that it runs through.
Here are some good maps that show the at least parts of the trail:
OHT Maps and Waypoints The last two maps on that page show the Richland Creek, Stack Rock, and Wollum at the Buffalo River areas. I've bushwhacked around this area quite a bit. The Stack Rock section of the trail runs through an area that has the highest concentration of Bears in Arkansas and probably the entire Ozarks area.
Just .8 miles upstream from where the trail starts/ends at the Wollum Ford on the Buffalo River is one of the finest swimming holes in the world. That'd be a great place to spend the last night and day of hike. It's accessible by car, but you probably will be there alone if it's the middle of the week in the Spring.
The Hurricane Creek to Fairview section is probably pretty nice. It runs along the creek and up into and around a holler. You'd probably have decent access to water and judging by the topomap there are probably some great "SSS's" (Super Scenic Spots) there.
Get Tim's Ozark Highlands Trail Guidebook. He'll tell you where the best "SSS's" are and his trail descriptions are as good as gold.
You might look into the Buffalo River Trail too. I think it and the OHT run together in spots and just about anywhere in the Buffalo River National Park is worth being. There are probably some spots on the OHT that I personally wouldn't go to. Not that they aren't worth hiking at all, it's just that I think there are better places to spend my free time.
You could easily spend weeks right around Hemmed-in-Hollow. The two highest waterfalls in the area are there. Granny Henderson's cabin, Snead Creek, Fishtrap Hollow, Rocky Bottoms, and miles and miles of trails. And you can set-up camp just about anywhere you like.
If I were to recommend a trail system to explore the Ozarks to my friends here it would be those trails near Hemmed-in-Hollow. I don't think any backpacker here would be disappointed.
