Firewood Regulations: Beginning March 1, 2015 only heat-treated firewood that is bundled and certified by the United States Department of Agriculture (USDA) or a state agency may be brought into the park. Campers may also collect dead and down wood found in the park for campfires. Certified heat-treated firewood is packaged and clearly marked with a state or federal seal. Heat-treated wood is available from a growing list of private businesses in communities around the park. Concessioners at Cades Cove, Smokemont, and Elkmont will provide heat-treated wood for sale during their operating season (typically March through October at Smokemont and Elkmont and through December at Cades Cove). Visit http://firewoodscout.org for a map of local stores and businesses that sell certified firewood. Additional information about this regulation.
