The National Park Service logged more than 323 million recreation visits across its 406 units in 2025, according to the agency’s own 2025 visitation report — but that total is wildly lopsided. Great Smoky Mountains alone drew 11.53 million visits, and an analysis of the same NPS visitation data by Forbes found it pulled in roughly 1,480 times more traffic than Kobuk Valley National Park’s 7,786 visits, the least of any unit in the system. Zion, Yellowstone, Grand Canyon and Yosemite round out the rest of the “big five,” each drawing between 4.2 and 5 million visits of their own. That leaves a huge gap between the handful of parks everyone plans a trip around and the rest of the system, where several parks offer scenery just as dramatic with a fraction of the parking-lot competition.
North Cascades National Park, Washington
With just 46,925 visits in 2025, per Forbes’ analysis of the NPS visitation data, North Cascades is one of the least-visited parks in the Lower 48 despite sitting a few hours from Seattle. The park holds hundreds of glaciers — more than any other park outside Alaska — and jagged, alpine peaks that rival the Tetons in drama without anything close to the crowds. Its remoteness comes from having almost no through-roads deep into the park itself, which keeps casual traffic out and rewards travelers willing to hike in rather than drive up to a viewpoint.
Isle Royale National Park, Michigan
Isle Royale logged 29,091 visits in all of 2025, per the same Forbes analysis of NPS data — fewer people in a year than the Smokies see most single days — because it’s an island in Lake Superior reachable only by boat or seaplane and closed entirely from late fall through spring. That isolation is the entire draw: no cars anywhere on the island, wolf and moose populations that have been studied continuously since 1958, and a backcountry silence that’s almost impossible to find in a park accessible by road.
Congaree National Park, South Carolina
Congaree protects the largest intact expanse of old-growth bottomland hardwood forest left in the United States, with some of the tallest trees in the eastern half of the country rising out of a floodplain forest that floods on purpose several times a year, replenishing the ecosystem. A raised boardwalk loop lets visitors walk through the champion-tree canopy without needing backcountry skills, making it one of the most accessible “genuinely wild” experiences in the entire park system — and it sits less than a half-hour from Columbia, South Carolina.
Great Basin National Park, Nevada
Great Basin is home to bristlecone pines more than 4,000 years old — among the oldest living organisms on Earth — along with Lehman Caves and some of the darkest night skies certified anywhere in the Lower 48. Its remote location in eastern Nevada, hours from the nearest interstate, keeps visitation low year-round, which means the marble passages of Lehman Caves and the summit trail up 13,065-foot Wheeler Peak rarely require a reservation or a crowd-dodging strategy. It’s also one of the few International Dark Sky Parks where a Milky Way view is essentially guaranteed on any clear, moonless night, no special timing or luck required.
Why the gap exists, and why it’s worth closing
The parks that dominate visitation numbers tend to share one trait beyond scenery: easy highway access and name recognition built over a century of postcards and road trip itineraries. The parks below them on the visitation list aren’t lesser — Isle Royale’s isolation and Congaree’s floodplain ecosystem are the reasons those parks exist as protected units in the first place, not obstacles to visiting them. Planning around one of these instead of the default big-five circuit trades a little extra logistics — a ferry schedule, a longer drive from the interstate — for the kind of solitude that used to be the whole point of a national park before the crowds caught up to the ones with parking lots big enough to hold them. None of these four require permits, lotteries or specialized gear beyond what any road trip already packs — just a willingness to look one or two names past the ones everyone else already has circled.
