The best time to visit the Smoky Mountain Park and enjoy the fall foliage is during the fall season from September to November. The weather in Tennessee can change with a snap of your fingers though, so even if these months are typically dry, pack rain gear just in case. To enjoy the view of the actual mountains, come during the winter season as the lack of foliage makes viewing the mountain ranges much easier. Tennessee is the most beautiful in the spring, so if you want to experience the best of festivals and the state’s flowers and vegetation, come between March through May.
