Great Smoky Mountains National Park, unlike some other national parks across the United States, doesn't charge for admission. It legally can't.

President Donald Trump's Making America Beautiful Again order will change park fees and the reservation system.

Trump’s order instructs Interior Secretary Doug Burgum to “develop a strategy” to increase entrance and pass fees at national parks for non-U.S. residents. This includes hiking up the price of the America the Beautiful Pass, which covers entrance and day-use fees at all federally managed recreation sites, for international visitors.
