The winding route to Plumtree through far western Avery County on U.S. 19 East is the very definition of a road trip. It’s the kind of byway most people would take only if this out-of-the-way hamlet were the destination itself. But for fans of beer and scenic beauty, a thriving brewery and a cluster of outdoor options are enticing reasons to tour the North Toe River valley’s flower-filled fields.
