Dan River is a 29.4 mile moderately trafficked point-to-point trail located near Walnut Cove, North Carolina that features a river and is rated as moderate. The trail is primarily used for nature trips, canoeing, and whitewater kayaking and is best used from March until October.
I've down the dan from up above danbury down to pinehall which isn't the whole thing but it is really nice. past danbury it is pretty smooth except for one or two spots. there is a book called "the dan river book" that gives good description and maps of the trail all the way to South Boston, VA.
