The Jim Bales Cabin on the Roaring Fork Motor Nature Trail. Robert Crootof photo. Great Smoky Mountains National Park holds one of the best collections of log buildings in the eastern United States. Over 90 historic structures—houses, barns, outbuildings, churches, schools, and grist mills—have been preserved or rehabilitated in the park. The best places to see them are at Cades Cove, Cataloochee, Oconaluftee, and along the Roaring Fork Motor Nature Trail. Self-guiding auto tour booklets are available at each place to enhance your visit.
