There are 63 National Parks of the 430+ units in the National Park Service (NPS) system and they are among the best places to watch wildlife. As with all of our Top 10 lists, this is a ranking of our favorite parks and not necessarily a true reflection of biodiversity or the likelihood of spotting the animals listed. Note: brown bears and grizzly bears are the same species, so we stuck with the Alaskan name. We have published a travel guidebook to the 63 parks with much more information about where to go to see wildlife (available on Amazon).
