At first glance, you might assume that bigger parks draw bigger crowds — but the data tells a very different story. Great Smoky Mountains, for instance, covers just 2,114 km² yet welcomed over 14 million visitors in 2021, making it the most visited park by a massive margin. Meanwhile, Wrangell–St. Elias in Alaska spans a staggering 33,682 km² — larger than some entire countries — yet saw fewer than 51,000 visitors that same year. Location and accessibility appear to be far stronger drivers of visitation than size. Parks in the continental U.S., especially those near major population centers or along popular road trip routes, consistently outperform their remote Alaskan counterparts regardless of how spectacular or vast they are. Age also plays a subtle role: many of the oldest parks, like Yellowstone (1872) and Yosemite (1890), remain among the most visited, likely because decades of cultural presence and developed infrastructure keep them at the top of travelers' bucket lists.
