The Great Smoky Mountains is in the Appalachian Mountains and is America's most visited National Park. In large part due to the highly varied elevations in the park, there is a wide range of plant and animal species. There are over 800 miles of trails, and a large section of the Appalachian Trail in the park as well as 80 historic structures. There is no fee to enter the park, but camping is charged on a nightly basis and parking costs money if you plan on leaving your car for more than 15 min. Three tag durations are available for purchase for all vehicle sizes and types: Daily - $5 Weekly - $15 Annual - $40 Parking tags are not replaceable, refundable, transferable, or upgradable. Each tag is valid for a single vehicle and must include a license plate number matching the vehicle in which it is displayed. Parking tags are available for purchase both online and onsite. Display of physical parking tags in each vehicle is required. Digital representations are not accepted. Parking tags are not location-specific. A parking tag is required to park anywhere within the boundaries of the Smokies. Parking tags are not required for motorists who pass through the area or who park for less than 15 minutes.
