With 63 U.S. national parks spanning a variety of ecosystems, the U.S. National Park System offers seemingly endless opportunities for outdoor adventure. Yet most visitors tend to gravitate toward our most iconic and well-known ones. In 2022, 52 percent of all recreational visits to a national park were to the 10 most visited: Great Smoky Mountains, Grand Canyon, Zion, Rocky Mountain, Acadia, Yosemite, Yellowstone, Joshua Tree, Cuyahoga Valley, and Glacier National Parks. (In 2021, the top 10 parks accounted for 55 percent of all visits.)

While each of those are popular for good reason, there are many others that are underrated and under-visited—whether because they’re less well-known, more far-flung, or simply overshadowed by other, more famous, nearby parks. As we head into warmer months and start thinking about ways to get outside, consider adding one of these 10 underrated U.S. national parks to your must-visit list for 2023.
