response: Yeah, but one thing to note is that 7 national parks are paired with national preserves, which are areas with differing levels of protection.
original_response: Same! Seven national parks (including six in Alaska) are paired with a national preserve and those are really pretty
history: I want to buy a pass and visit all the national parks in the US. That sounds interesting, which of the 59 national parks would you want to visit? I didnt realize they were so many. Do you know which park is the most visited? Unfortunately, I do not know but I can tell you that Yellowstone was the first one signed into law by President Grant in 1872. Have you visited any of the parks? Ive only been to the Grand Canyon. I haven't visited any but would you be interested to know that the National Park Service was created by the Organic Act of 1916? Who signed that act into law? I'm not really sure but many current national parks had been previously protected as national monuments. I think its great to protect these  sites especially from big business.
knowledge: Seven national parks (including six in Alaska) are paired with a national preserve, areas with different levels of protection that are administered together but considered separate units and whose areas are not included in the figures below.
