Choosing what to do when visiting a national park is not an easy task. There are just so many options! While most travelers just drive in, take some pictures at the lookouts, and might stay one to two nights in the park, we recommend exploring each national park on a deeper level. Learn about the geologic or natural history of the area or experience unique outdoor activities in the park. To be qualified as a national park by the National Park Service, only 3% of the entire park area could be used for infrastructure, such as highways, trails, campsites, visitor centers, lodges etc., while the other 97% are protected areas. There are at least over 100 things we could list when visiting a national park, however, we will only highlight the absolute must-do’s.
