Given your comments thus far, I would recommend Wilsons. Its not world class for sure, but it is on the French Broad river, adjacent to Carrier Park (nice), and near the River Arts District, which is where the New Belgium Brewery is located. Sierra Nevada Brewery is a much see, its in Fletcher, so figure a car drive to that one.
I live west of Asheville. October is PRIME TIME, expect camping to be crowded (full). So plan ahead.
Once you start camping out a ways, I would recommend Maggie Valley. There are several campgrounds there. But you will be 30 to 40 minutes from downtown Asheville. I live in downtown Waynesville, we have several microbreweries here too. Boojums is the best. Very nice restaurant too. Microbreweries are opening up all over western NC right now. But the Asheville brewery scene tops them all.
Be sure to stop at the "Vortex", and get a donut (or two). They are very close to several microbreweries, and worth a stop. If you go, don't be surprised if you end up going back a time or two.
Wilsons is adjacent to I-240, so plan on road noise. Bear Creek Campground is your other choice. Bear Creek is pretty close in, maybe a mile from Wilsons. Neither of them gets stellar reviews.
