Most visited national parks? Depends on who you ask

What are the top ten national parks in the United States by visits? That depends on whose statistics you go by. The American Recreation Coalition recently published a top ten list, based on statistics provided by social network giant, Facebook. The Facebook stats are based on users who reported "check-ins" to national parks on its network site.

Now compare the social network stats to those provided by the National Park Service (NPS). In this case, the numbers are based on the actual number of visits made to the parks in 2013.

No doubt our readers have their own national park favorites.
