With regards to the Smokies being a national park and being “free”, well…. it was. As of March 2023 you are now required to have a parking pass if you plan on parking anywhere in the park for longer than 15 minutes. 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 at any visitor center. (i.e. Sugarlands etc..) Display of physical parking tags in each vehicle is required. Digital representations are not accepted. 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. The money acquired through these parking passes will be used to maintain the park in a variety of ways But hey.. Spring time is upon us once again! Thank you for the very informative video.
