Take Isle Royale National Park in northern Michigan or Voyageurs National Park near the Canadian border in Minnesota, for instance. These destinations see fewer than 250,000 tourists a year, combined. Both offer gorgeous fall colors, but you must bring all your gear to Isle Royale.
Farther north, fall can be unpredictable yet pristine in Denali National Park. Because it’s so far north, fall and winter can mix in Alaska. But the crowds aren’t around as tourists enjoy these subalpine forests turning a magical red and orange.
Neither park requires payment to enter, so these numbers may not be absolutely accurate. Official data says fewer than 150,000 people visit Great Basin, and only 30,000 visit the North Cascades, in spite of their easy access.
