Old logging trails are now ATV trails. Some water crossings, but DO NOT stay in water any longer than necessary. Greenies are trying to shut down the riding due to "water quality" issues.
Otherwise, fabulous miles of trails. Local law allows for riding on county roads. You can use these to go to a local waterfall to cool off.
The trail up a mountain side to a viewpoint is very challenging, with some rock crawling involved. Novices beware.
Local rv campground by same name (Wolf Pen Gap Campground) has cabins and rv camping, just an easy ride from one of the trail heads. They also sell gas.
