I would certainly consider heading to Brevard area and camping. Tons of trails to ride in the area, you can camp at Davidson River campground and you’ll be close to DuPont, Pisgah, and Bent Creek. The nice thing is there is plenty to do for the family in the immediate area with hiking, shopping, and Asheville is only 15-20 minutes away. Search here on Singletracks as there are a number of articles about the area and trails.
