There are 63 officially designated United States National Parks. Each question below lists two of these parks along with a third location that is not a U.S. National Park. See if you can identify the imposter for each question.
The "Imposters" could be state parks, national parks in other countries, or just random locations.
Be careful: Some of these locations have received other designations from the United States National Park Service (such as National Monument, National River, National Historical Site, National Parkway, etc.), but are not considered one of the 63 U.S. National Parks.
