Taking a relaxing drive through the Great Smoky Mountains [1] is a great way to see its most prominent attractions. During weekends in the summer and October expect long lines of traffic on the most popular roads. Try to choose a weekday and strike out early to avoid crowds.
The mountain ascents and descents can strain your vehicle. Watch your engine temperature carefully, especially in the summer, and use a low gear when coming down the mountain. Slow-moving vehicles should use pull-outs.
Several park roads are closed in winter. If you plan to visit between November and April, call the park first to confirm closures.
As you drive through the park, you will see signs for Quiet Walkways. These trails are designed to encourage you to get out of your car and stroll for a few minutes through the forest. Some of the walkways are short—about half a mile—while others join up with longer trails. Walk as far as you like and then turn back and return to your car the way you came.
