Going to Knoxville TN and taking the drive over to the Smokey mountains. I know the mountains are huge and can be accessed from other states.

Looking for the best trail/hike that’s accessible from Tennessee. I’ve never hiked either so I don’t know what to expect. We are renting a car and wanted to drive a trail and then maybe walk some of the waterfall/ river areas. It’s only a day trip so we want to see the most during our time there

Can we get tickets there? I know you can online but I don’t have the rental license plate to print in advance
