What to expect on Brannon Mountain – Potato Knob Mountain loop from Brown Mountain

Planning your visit

Given the remoteness of many Appalachian gravel routes, including this one, be prepared for areas with no cell service. It's highly advisable to carry a water filter, a fully charged GPS device with the route preloaded, and a waterproof map as a backup. For the varied and often rugged surfaces, a gravel bike with large tires (42mm or wider) or a rigid bikepacking bike is recommended, along with low gearing to tackle the steep ascents.
