There is confusion about the specific list being reported, with some outlets discussing the most photographed or visited national parks in the US, while others mention state park campgrounds, popular attractions, or beautiful hikes around the world. Some sources appear to be referencing data from the park service or other organizations, but the focus and scope of the lists vary. The original story claims to identify the 10 most photographed national parks in the US, but other outlets have different criteria and geographic areas in mind.
