A proposal to build a mountain bike trail network at Great Smoky Mountains National Park is being floated, one that could build nearly 13 miles of trail within a section of the Foothills Parkway transportation corridor that has not been developed.
Mountain bike enthusiasts long pushed to see more trails in national parks opened to their sport, but concerns over conflicts between mountain bikers and hikers have largely blocked those efforts.
