Currently, there are 63 national parks in the U.S., alongside countless more national monuments, national recreation areas, national seashores, and national historic sites overseen by the National Park Service (NPS). These protected spaces represent some of the most important natural and cultural landscapes in the country.
The NPS recently released its latest annual visitation data which will help us (and you) decide where to plan your next hike, whether you’re looking for a communal vibe, or a more secluded and isolated experience.
With almost 13 million visits last year, the Great Smoky Mountains remain undefeated when it comes to the most visitors of any national park. But other, no less spectacular parks see a fraction of those numbers. If you want to head off the beaten path, here are 21 of the least visited NPS service sites in the U.S.
