In spite of their general remoteness, most southern spruce-fir forests are accessible via federal and state highways. The Blue Ridge Parkway passes through the spruce-fir regions in the Plott Balsams, the Great Balsams, the Black Mountains (N.C. State Highway 128 connects the parkway to Mount Mitchell), Grandfather Mountain, and Mount Rogers. In the Great Smoky Mountains National Park, U.S. Route 441 climbs to Newfound Gap amidst the Great Smokies spruce-fir stand, where it intersects the Clingmans Dome Road. The Roan Mountain spruce-fir stand is accessed via state highway—designated as Highway 143 in Tennessee and Highway 261 in North Carolina—and a paved road accesses the gap between Roan High Knob and Roan High Bluff, where there is a large rhododendron garden.
