Seeing wildlife in a national park is one of the most memorable parts of any trip. Unlike zoos or preserves, national parks allow animals to live and move freely in their natural habitats. With the right timing, locations, and expectations, some parks offer incredibly reliable wildlife encounters.
From massive herds of bison to wild horses and tropical fish-filled coral reefs, these national parks stand out as the best places in the U.S. to see wildlife responsibly and up close.
